Decrease in fuel mileage

[MAZDA Kitten]

So consistenly before I was getting anywhere from 340-360 at half tank

Now I am consistenly seeing 300 on the nose at half tank

I dont idle the car (only a minute or two on really cold days), driving habits havent changed... nothing

I am think maybe the air filter? I have a K&N and it hasnt been cleaned since like the spring :blush

[Chuckie]

would you like to trade with my 430 a tank?

[justin]

I am think maybe the air filter? I have a K&N and it hasnt been cleaned since like the spring :blush

That might be your culprit. Your engine is working hard to bring more air in, and b/c the filter is dirty, its getting tougher. So your using up more fuel to do the same job.

Clean the filter, see what happens. I'd be willing to bet your mileage goes back up again.

[Flagrum_3]

Alon with the filter you might want to check your tires... With the up and down temperature changes recently you could have lost some air in your tires.

Sounds like your car is actually starting to sucumb to the fuel milage the rest of us have!!!

Clean the filter, oil change, tire pressure.

Good idea...
Havent thought about that
What should be PSI for winter driving? 30-35?

I just googled this and turns out on some other car forums people are experiencing a drop in gas mileage due to winter blend gas

We'll see; I'm gonna pick up a K&N filter cleaning kit and check tire pressure and go from there

Thanks guys http://images.zeroforum.com/smile/emthup.gif

[Effin Itai]

My car is also a big fat pig! Yes, I'm getting bad fuel economy also. City driving and winter cold weather is always the culprit.

[aznkid.com]

i can't relate with my mazda 3 because i've only had it for less than a week but my accord get about 600-625 to the tank in the summer, while only getting about 475-500 in the winter

[bRANDO]

what about the change in tire size from summers to steelies? some of us dont have a big change, but what about those of you runni 18"s drop to 16"s?

I believe it should be 32psi, thats where I set mine as close as possible anyways.

I believe everyone should notice a increase in fuel consumption in the winter for many reasons, ...engine runs in rich setting longer (cold starts), ...tire slippage (slick roads), slush and shit on the underbody etc, etc;...the fact your still getting 300 to half tank is pretty good I would say, I'm lucky to hit 250 at half, mind you my present tank is 280k still haven't touched center...yee ah!.

Let us know the outcome.

[Fuman]

350km a tank...
i get 250 if im lucky...

[The Dude]

I usually get about 300km at the half tank mark. The most I have got at half tank is 325km. My winter tires are 205/50/17 at 35 psi...

[Hazy]

Getting 340-360 at half a tank is really good. I do 80% city driving and 20% hwy. I only get about 200-250 at half.

[majic]

keep this thread on topic of decreasing mileage in winter..

there are too many 'how far can you go on a tank' threads already..

finally MK is getting 'shitty' mileage ;)

[JPAV8S4U]

LMAO! damn... I drive mainly highway.... on cruise control (yes that helps with mileage) at 100kmh...... and I get 500 in the winter per tank... 600 summer. I dont if I ever got over 700 like MK.... jealousy

[Wild Weasel]

heh. And people make fun of me for driving 110! :)

Hmmmmm maybe I should edit :D HEY!!! Everyone look at Wild Weasel!!! (jeff runs away and edits)

no, they are making fun of you bc you drive a sunflower ;)

:pop

[MAZDA Kitten]

Lmaooooooooooooooooooooooo

[EvilEric]

What's your mileage now that you cleaned the filter? How did the cleaning take you to do?

[majic]

i doubt she can tell you after a DAY of driving.. give it a few tank fulls (a month) and you'll know

[mazda lover]

I get about 250KM to a half a tank, according to the gas gauge. Get an average of about 30MPG, sometimes more if all highway. Car not driven in winter so don't know if I would get lower mileage/
2.3 Auto. 2005

[majic]

there's no way that you can get 30mpg hitting half tank at 250km.. 300km i can understand.. 250km .. NO way.. for me, ~280km @ half tank ~ 8.8L/100km ~ 26mpg

[Flagrum_3]

Sorry but, 8.8L/100km = 32.3 mpg ...so its quite possible to get 30mpg with 250km @ half tank.

No it doesn't. You're using Canadian-window-sticker-scam hokey math. Using a proper US gallon (which is how we should be comparing numbers if we're talking in MPG) then Magic is right. It's around 26 mpg.

[Wild Weasel]

Actually... on that note... when the car's trip computer gizmo does the math... I wonder what gallon it uses?

[majic]

wow.. weasel agrees with me :loco :hawt

in google (http://www.google.ca/search?q=8.8L%2F100km+in+mpg&ie=utf-8&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a) i trust :D

[Wild Weasel]

Keep in mind that Flagrum is correct if you're doing the calculation using British gallons. This is how it's done on Canadian window stickers to make all the cars look like they're getting better mileage than they really are, when compared to US literature.

That's why I'm wondering what the little computer thing is using on the Canadian cars when reading out in MPG. I guess I'll find out once I get my car and can compare what it says to what I calculate.

[majic]

i understand that part, but if you compare a US spec 3 and a canadian spec 3, it would only make SENSE to compare apples to apples and the US gallon conversion allows you to do that (although i just checked US website and the highway fuel consumption numbers there are off by 2-3 gal).. how often do we compare/talk about CAN cars side by side european/asian ones?

[Wild Weasel]

I agree with you 100% on that. I think the Canadian window stickers are a complete scam, meant to mislead consumers.

[JPAV8S4U]

Personally, I wonder what the computer uses for the signal..... Is it using some sort of "in line" transmitter? is it using a ref from gas pedal position (Ill bet on that one)..... or is it using some sort of flow valve? If the car is using gas pedal position and not an in line or flow valve solution, then the number will be horribly incorrect as they do not and will not account for outside temperature and current atmospheric pressures. During some days, this could prove to make the actual reading almost useless.... Do I sound like a pilot?

[Wild Weasel]

The ECU knows the fuel pressure and how often the injectors are cycling, right?

I don't know if it's doing so, but it could use that to determine fuel usage at any given time and then just use the speed to make the on-the-fly calculations.

[JPAV8S4U]

I don't know if it's doing so, but it could use that to determine fuel usage at any given time and then just use the speed to make the on-the-fly calculations.

Once again.... if the ECU is reading fuel pressure, then the number will be off thanx to dif temps and pressures outside the cars system. As far as speed numbers are concerned, that is a huge weak link in the system as difference rims/tire combos will throw that off as well. The ECU also know throttle position... hence why I think the system is a simple one and only uses that input. By taking multiple inputs into the calculation, it really complicates the system and starts to make it expensive. I highly doubt mazda is using multiple inputs to come up with the numbers you see. I think it is a gizmo.... a simple one.

[Wild Weasel]

Well there's no getting around the wheel/tire issue when it comes to calculating mileage. If people put on the wrong size, then there's no way the car can know that short of having a GPS antenna to figure out how fast it's going. All it knows is how fast the wheels are turning, right?

Liquid fuel density isn't really going to change to a huge extent with temperature changes. I don't think that will have a big impact if it's using pressure and injector cycles to determine fuel usage.

[Flagrum_3]

No it doesn't. You're using Canadian-window-sticker-scam hokey math. Using a proper US gallon (which is how we should be comparing numbers if we're talking in MPG) then Magic is right. It's around 26 mpg.

Sorry but your also wrong! There is no window sticker scam its "Proper Canadian measurements" 1 Canadian gallon = 4.55 l ...the Americans use a smaller gallon which is I believe 3.89 liters or something like that.In Canada we use Metric and measurements are derived from the British Imperial system.

So if you were to grab a fuel consumption guide from the Ministry of Transportation which states all vehicles fuel consumption, its "IN Canadian Measurements"

The window scam you are thinking about is the fact that when companies fuel test thier vehicles it is under ideal conditions; sitting on a dyno no hills, no wind resistance no turns, running at 90kph steady etc; etc;...in the states they have altered their test to be more accurate and the average difference is approx 2 mpg American.The Canadian government is now talking about changing the system also.

This is why we use L/100km. It's metric, and it's unambiguous. You're talking about Canada using the metric system at the same time you're arguing about how something is measured that uses miles. It doesn't make any sense. The only reason to list a figure for MPG at all is to compare the numbers to literature from the US. People see the L/100km figures and don't know how to compare that to the numbers they read on the Internet from American media. Of course, when they're given the "Canadian" mpg figures, most people don't understand that they also can't be compared to American literature. So... they compare them... and lo and behold, they think the car they looked at in the dealer lot is more fuel efficient than anything else in its class.

It's misleading and it's a scam.

Can you even buy gas measured in British gallons anywhere in the world?

As I said, the proper "Canadian" metric measurement is L/100km's.

This is different, and not so much a scam as it is a completely outdated way of measuring this. It's misleading, but so long as everyone is forced to play by the same rules, at least you can compare models and get an idea of which is better. Everyone should know by now that you shouldn't expect to get the mileage it shows on the stickers.

You still don't get it...yes metric is in L/100km's but if people are not smart enough by now to realize our gallon is larger than the Americans its nobody's fault but thiers...Its not misleading at all (Its called ignorance).

Oh by the way everytime you buy gas in Canada you might not be buying in British gallons, but our liters are measured in the British system.So how would you be able to accurately compare your gas mileage whilst filling up in Canadian measured liters to American specs if you don't do some conversion.

I have been figuring out my mileage for decades now and am not confused. I average 32mpg with my 3 and thats a Canadian gallon not American.You want it in American drop it by 1/5 which by the way equals 25.6 mpg...its simple, not confusing and definitly not a scam....more like an uneducated public.

i think people REALIZE it but why do weird ass math to get to mpg rating ANYWAY?

for arguments sake, you drive 500km and fill 40L the L/100km conversion is SIMPLE (divide L by km travelled and x by 100) 40/500 * 100 = 8L/100km DONE

we drive in kilometers not miles, so to get an mpg conversion there are additional steps involved

500km / 1.609 = 311miles
40L / 4.55 = 8.8 gal UK
40L / 3.785 = 10.6 gal US

311 / 8.8 = 35.3 mpg UK
311 / 10.6 = 29.3 mpg US

sure you can just use the conversion factor of 282/x and 235/x respectively (but then again who knows about THOSE), where x is mpg or l/100km but why? the only plausible answer is to compare it to the fuel economy of the cars to the south of us!!!

of course car dealers in Canada will show off the UK ratings.. hell, if you ask a joe shmoe to pick a truck that could haul 3159lbs or 1492kg, which would they pick? i BET you they'd go for the one advertised in pounds yet they would be picking the inferior one (if the hauling capacity was the deal maker)

consider two cars that do 10L/100km and 12L/100km, if a UK system is used, the mpgs are as follows 28.2 and 23.5 (visually 5mpg difference, actually 4.7mpg) but if a US system is used then 23.5 and 19.6 (visually 3-4mpg, most people will round up the 19.6 to 20 and the 23.5 will most often get dropped to 23 when in fact it's a 3.9mpg difference) THAT isn't as big as 5mpg!!! anyway..



Oh by the way everytime you buy gas in Canada you might not be buying in British gallons, but our liters are measured in the British system.So how would you be able to accurately compare your gas mileage whilst filling up in Canadian measured liters to American specs if you don't do some conversion.


do you THINK and do calculations in miles and in gallons? if so, great for you but i assure you most people do NOT. when you see a sign for an exit "yonge street 3km" do you think.. boy, that's like just less than 2 miles and then convert back to your odometer reading, which is in KM??? :loco

yes, if you're driving 100kph (60mph for arguments sake) you will be going a mile a minute (cool) but go 120kph and you'll be doing 2km/minute (much cooler b/c all the signs are in kms so you can estimate your arrival time much easier)

want a cookie?
i am pretty sure others are fine with L/100km

if you are saying that the public is uneducated, do you THINK they will know how to compute fractions? lol.. you're asking regular folks to do fractions and mpg conversions in their head. you might be THAT talented but i assure you others will have more difficulties and wouldn't even know how to convert to and fro without online tools..

[lukel90]

MAJIC...when did you change professions and become a professor....lol....your last post read like it was written by my high school math teacher....it was a weird feeling reading that...brought me back to my youth.....aahhhhhh... i miss high school...any how...

MAJIC is mostly correct

100kph is 62mph not 60...( just being a dink)...lol

[majic]

100kph is 62mph not 60...( just being a dink)...lol

i know, that's why i said for argument's sake.. easier math when you round it off.. :AH

[MrJWU]

Here's my latest:
314km for 40.3L = approx. 7.85km/L

How shitty is that? I'm taking my car into MOT next week hopefully to get this checked out....

there's no such thing as litres being "measured in the British system". it was never based on the Imperial measurement but rather an aside of the System Internationale (Metric) definition of volume.

A litre is a litre in the USA, Canada, Europe, etc.

Is it using some sort of "in line" transmitter? is it using a ref from gas pedal position (Ill bet on that one)..... or is it using some sort of flow valve?

During some days, this could prove to make the actual reading almost useless.... Do I sound like a pilot?

there is an ecu reading of "Fuel Level Input" which is given in terms of a percentage of fuel in the tank (at least on a scan tool)....it can convert that %age into a litre value, seeing that it knows the fixed value of the tank being 55L.

given that it monitors the fuel level over time, as well as kms driven over time, it can perform calculations to give fuel consumption (avg, instantaneous, etc). it all boils down to calculus ;)

[MAZDA Kitten]

I am happy to report that I hit 330 at exactly half tank and that was with rather more aggresive driving

So in the last week the car had an oil change (synthetic), tranny oil change (Redline MT90) and cleaned my K&N air filter

So far so good :)

This is unreal! I dont believe.... This I have to see! what do you drive 80? never shift over 2500? only on cruise control? 100% highway? If non... then your car is a one off! and I want it ! hell... you get more mileage than a hybrid! SERIOUSLY! I get 500ish out of a tank in the winter... 620 Summer. and I do all of the above..... well not 80kmh... more like 100kmh...

I take 407 every morning which I'm doing anywhere from 120-140ish
Then I am in stop & go driving conditions (which to me is more like 'city driving' than highway)
Then usually when I go home its later at night so again, I'm doing anywhere from like 120-140
Thats the majority of my driving

During the weekend I run errands and do whatever so again, city driving conditions.
I shift 90% of the time before 3000rpm
Its a 2.3 GT sedan
The car has had Shell bronze all its life (maybe its the 3 tier gas? I dont know)

That is why when I started to get 300 at half tank I was concerned because I know my car and I know what its capable of

don't get your panties tied up in a knot just because you're a disgruntled geezer who learned something 40 years back or so and refuses to accept the reality and perhaps change..

looks like you need a lesson in spelling in addition to my math lesson ;)

and to answer your question, most of us compare the mileage on our Canadian vehicles in L/100km (some even use km/L).. as for why compare to a "Jack Shit" in the USA as you ignorantly put, the references to M3F and other US sites are far greater that to UK sites.

once again, MOST people are familiar with the 3.785L in a gallon - every time you PISS in a urinal (pretty much 90% are 'american standard' brand) it says 1gpf/3.785Lpf..




Do Americans use L/100km I don't think so, and a liter is a liter if its here or anywhere else in the world but if your going to convert to MPG which is exactly what you did in an earlier post, do it right.So please stick to L/100km then so theres no more confusion.


they don't... they use miles and american gallons hence the logical mpg calculation.. face it, here we use L/100km the most and when mpgs are used the questions are bound to arise (UK or US).. anyway.. you do it your way.. i do it my way and we're all good as long as the numbers are unambiguous (followed by the proper units such as mpg US/mpg UK) then there should be no confusion..

First of all I'm far from a disgruntled geezer and I don't wear panties, maybe thats your style, I don't care.
What change are you talking about? We converted to Metric here in Canada in the mid 70's...I'm quite familiar with it....I didn't realize spelling was of much importance on this board, ...maybe your just anal about it!

Your analogy to urinals makes great sense, I guess you spend alot of time there....But it still doesn't change the fact that in Canada our Gallon is 4.55 litres not 3.78....If you want to compare with the US, fine do it at your leisure I have no problem with that, but on this board we should simply use Canadian measurements to keep it simple.

I never said anywhere in this discussion to compare anything with the UK, What I said is why compare with the US at all, or use their standard when we are comparing within our own group the mileage we get with our 3's here on the board....it seems more logical to stay within our countries specifications.

Anyways maybe from now on IF anyone is going to post their mileage in MPG then maybe specifying whether its in US or Canadian would be a worthy inclusion to clear things up.....sound reasonable?

Last thing I wanted was a simple question why I got low fuel mileage turn into a spat

Instead

Lets have a good ol fashioned STREET BRAWL


But
Back on topic...

Dont forget to clean or replace your air filters people!!!! :) :) :)

[majic]

yes ma'am :chuckle

lol... 300km @ mid tank i would HARDLY consider 'low' then again... it your black beast ;)

[Flagrum_3]

I take 407 every morning which I'm doing anywhere from 120-140ish
Then I am in stop & go driving conditions (which to me is more like 'city driving' than highway)
Then usually when I go home its later at night so again, I'm doing anywhere from like 120-140
Thats the majority of my driving

During the weekend I run errands and do whatever so again, city driving conditions.
I shift 90% of the time before 3000rpm
Its a 2.3 GT sedan
The car has had Shell bronze all its life (maybe its the 3 tier gas? I dont know)

That is why when I started to get 300 at half tank I was concerned because I know my car and I know what its capable of

MK did you just switch to synthetic or have you been running it for a while? ...My driving is very similar to yours except I don't usually stick to the under 3k shift point to religiously and I'm not getting your numbers, ...pretty close but not quite as good, mind you I don't have a K&N filter....maybe that's the difference?!
Also have you ever calculated your mileage using a full tank? (L/100km). It would be interesting to see your findings.

Never did L/100km thing but i always used my half tank as an indicator because I always ALWAYS fill up when I get gas (I never do 10 or 20... Literally everytime I dont care how much gas costs I fill her up to the top)

Anyways;
For transmission oil I just switched it to synthetic this past weekend
The car has 96,000km

I started using synthetic engine oil at 80,000

I noticed an increase in fuel mileage when I installed my Vibrant exhaust (i.e. without Vibrant I was yielding about 320 or so at half, after the Vibrant I was consistently getting the 340-360)

Majic for smoe raeson lkies to piss on poeple. Why, jsut don't konw. I think he thinks we are all stupid noobs, hes a know it all. He makes it unpleasent to contribute to this forum. I rarely contribute as I feel I will be attacked by him, showed to be an idiot. I don't even go to any of the meets because of him. He is a cancer to a other wise very good forum with great people and their input. I have had problems with him before, he just, for no reason, comes out and makes you feel like an ass. And Majic please don't send me a PM, I won't read even if you do,tell me to my face for all other members to read.
I am sure it won't be pleasent as it is your nature. Sell your car and move on to a different forum.
Maybe I am too sensitive. If it is just your sense of humour my apology.

Whoa whoa whoa. No public stuff here. If you have an issue take it up with him by PM, and he the same. No flaming on threads period.

I just want to note one thing. In person Majic is a pleasure completely differnt from what he appears to be on the forum.

I am shocked you wouldn't come out to meets because of Majic! There are more than enough people that if you felt like it you wouldn't even have to come in contact with him. Don't let an individual discourage you.

To everyone out there. I was new to this forum less than a year ago, so in a sense I am still new here. Majic picked on me a bit when I started out, i didn't know a few things. But he never means anything, he just is an uncensored guy who will tell anyone what he thinks. If you find him offending and attack/flame him it only encourages him as it would anyone. With that in mind, he honestly never tries to offend. If you don't want to pay attention to him don't the internet is larger enough.

j/k

[CoolColombian]

Don't get fooled by MKs case, her car is unique, I can't still figure out how she does to get all that mileage.

I've have intake and exhaust for a year and a half aprox and had never got more than 420 - 450 KM from a full tank and I've also been using synthetic oil (Mobil 1) since the first oil change, the car is now 30900KM and the max i've got is 520km in my way down to NYC last December, so don't think that and exhaust and an intake will increase your mileage, it will mostly decrease it.

One thing I have to remark, last week I put 91 on my car b/c the gas station had run out of 87 and 89 and was offering 91 for the price of 87 and luckily I had to fill it up, the car felt the same as if was using 87 but I noticed a very good increase on mileage, almost 10km/L on mix driving which I never expect before with 87, I now the prices aren't helping to keep filling with 91 but it surprised me b/c the consumption and the timing of the engine should had been set up for 87 octane gasoline.

[Flagrum_3]

I don't know if her car is unique, what could possibly be 'so' different? ... but maybe its MK's style of driving.It is understood that a smooth easy style of driving will gain you fuel economy and I'm not talking about granny driving here but smooth accelerations, steady rpm cruising, easy 'no' down-gearing braking, etc; etc; ....I am acquirring almost as good mileage numbers as MK (320km @ half tank-summer and 280km winter) and drive very similar to her except my shift points are a little higher which is probably one of the reasons, but I am confident once I get the Vibrant exhaust and MS Intake installed my numbers should go up, its only logical with increased air intake and better, i.e; faster flowing exhaust gases.....as long as I keep my zoom zoom in check!!

MAZDA Kitten,
When filling up, write down your car's mileage.

Like say tomorrow you fill up, on the receipt before you pull out of the gas station, write down either your trip counter, or your overall mileage or both, and reset your trip counter.

From here on in, do the same before pulling out of the gas station, and you'll have a fairly accurate fuel consumption measurements.

[majic]

she's too lazy to do that ;) trust me.. she gets 320-350 to half tank and that's how she gauges it (pun intended).. lol.. i get 270-280 usually and best was 311..

btw, MK.. have you had your ECU flashed? ever? i know you've had wicked mileage since day 1 but it doesn't hurt to see if it's been flashed (that you know of)

[Skarbro]

I wish that everyone had the fuel/kilometrage meters like the 2006+ cars. I use it every day.

With regards to figuring out the full tank efficiency...

Measuring the fuel efficiency by means of where the half-tank falls appears to me to be a somewhat inaccurate way to do it. Who's to say that half-tank is ACTUALLY half a tank? I know that in the J-Bodies that the second half of the tank goes down a lot faster than the first, so it's difficult to tell where half really is unless you empty the tank completely and measure throughout.

Also, since the odometer is analog - you are essentially eyeballing the half-tank mark. I know in my car, driving 20 kms on the highway doesn't really move the needle that much at all.

And are we taking into account the excess fuel over and above full?

I guess it is almost on equal ground if everyone measures by the same half-mark. But it shouldn't be multiplied by 2 to get the efficiency per tank. Any error that you make over or under at the half-mark would be multiplied by 2 when you convert that to full tank. (Which is why I guess I see a lot of people stopping their measurements at the half-tank reading. That makes sense)

Are all the gas tanks exactly the same shape for the sedans and hatchbacks over the years? I'm sure they probably are, but sometimes gas tanks are re-designed.

There also has to be some kind of standard deviation.

I guess that some of these methods are all that are availably since the cars are fitted with true meters. Just take it with a grain of salt though.


That said - I'm achieving almost exactly the same kilometrage during the winter as the summer - which is about 600 km's/tank (according to the fuel efficiency meter) for about 90-95% city driving (my estimate).

[Skarbro]

I just have to point out that using higher octane gas does not give you better mileage! There are a couple of threads already on this. :)

[Wild Weasel]

You can measure it accurately by simply recording your mileage at each fillup, and how much gas you put in.

This will be more and more accurate over time as everything averages out.

Basically... when you fill the tank, write your mileage on the back of the receipt and then reset your trip meter.

If you do this every time, you'll know how much gas you used to go exactly that many km's.

Of course, there will be small differences in how much you fill the tank and what sort of driving you do, so this is why it becomes more accurate as you average it out over time.

[Skarbro]

One major factor not included in these calculations is the average km/h over the duration of the tank. We sometimes use the highway a lot more in certain times for whatever reason.

The nice thing is that this measurement is in the fuel computer in the 2006+ cars.

I'm going to start keeping track of all these factors as outputed by the computer and report back later. That should give a more accurate figure to work with I guess.

[Gizzmo_jr]

Do you reset the fuel computer at fill up? Worth doing so or gives out the same numbers regardless.

I suppose now that I think about it, avg/consumption and avg/speed would be only two effected. Remaining fuel, and current/consumption are dynamic.

im pretty sure remaining fuel uses avg consumption in order to be calculated

[BLKOUT]

I had my ECU flashed when I had warranty work about 3 weeks ago. I have noticed an increase in the mileage. I am curious to see how much better it will get when the weather warms up.

[Caz]

I drove to Ottawa to visit family a few weeks back and did most of the trip (90%) with the cruise control set at 110 km/h. I have been burned with speeding tickets on this route on previous trips and it saved my ass on this one as I went thru 2 speed traps. On the way there I got 390km on half a tank (needle on center of the line). It was 0c outside and I wasn't running the heat at all.

I didn't have my camera with me or I would have taken pictures to back up this, I will next time I make the trip. I will also take acurate odometer readings.

[majic]

liar..

no pictures no proof!

[Caz]

Try it, you know what a dif. cruise can make. You even did your little test.
I went almost the whole trip without touching the gas or the brake.
I left on friday mid-morning and there was next no traffic.

[Skarbro]

I can understand getting good kilometrage on a trip to Ottawa with cruise on at 110 km/h:

- Flat roads with cruise = better mileage (no driver error with the pedal going up and down all the time).
- The wind will be most likely helping you.
- 110 km/h is not too fast - in most cars 67-100 km/h is the optimal speed for fuel efficiency.

[Wild Weasel]

Technically you can get better mileage by driving the car yourself... but it's not worth the effort. :)

There was a great Top Gear episode where Clarkson drove a diesel Jag some ridiculous distance by doing just about everything humanly possible to conserve fuel. It was amusing to watch... but I sure as hell wouldn't want to put that much effort into saving gas. :chuckle

[Caz]

I will also add it was the most boring 4 hours I have ever spent behind the wheel.

[majic]

i NORMALLY cruise at 3K rpm (110kph) but my highway distances are 40-60km and sometimes even though it's hwy driving i hit traffic.. i don't dispute you'd get BETTER fuel economy cruising at 110 but 390km.. wow.. not bad.. then again if i reduced my speed from 75-85mph to 65mph when i hit 311km at half tank down in the states, i might see the same result :P

but when you're in the car for 8hrs and you can shave off an hour.. it's DAMN worth it..

It wasnt a diesel Jag
it was actually an AUDI A8 V10 TDI

[Wild Weasel]

Yeah, that was the one. :chuckle

Incidentally, on longer road trips I also cruise around 110 in the right lane. I'm planning on doing the next one at 120 just to quantify the difference in mileage so I can decide whether it's really worth it.

Anything over 120 brings up the possibility of getting tickets, so I'll always keep it under that just so I don't have to concern myself. Just cruise along and enjoy the trip. :)

I have always wanted to see how far I can go. I went until it said 1 km remaining before. I just can't bring myself to go any lower than that as I know I would have to go for a long walk for some gas.

[super_vixen]

wow....I envy you all. I'm lucky to get 315-330km off an entire tank...I'm lucky to see 150-170km at half...

I've been keeping track of my gas mileage issues all winter (the issues actually started last spring) and if things haven't improved by the summer, I will be taking the car in to be looked at.

I had better mileage off all my previous cars, so buying brand new and getting this deal, its not so good.

That's pretty sad fuel mileage, ...Have you tried anything to improve it? Like using different gas ie; Shell or Esso vs Sunoco etc; or disconnecting the battery for a short period? .....and instead of waiting why not just take it to the nearest dealer asap, explain the situation and ask them to flash the ECU it shouldn't take but a few minutes and maybe it'll save you some money.

I've changed the air filter, had the oil changed, checked tire pressure, tried different gas, tried driving entirely by the speed limit EVERYWHERE (not always easy to do), I've tried driving my auto with the manual option.

Haven't tried the battery...never heard of that relating to gas mileage so never thought of it. How does that affect if?

I've mentioned it to my dealer a few times, and they always chalk it off to be normal. I've disagreed, but because I'm female I'm often taken as not knowing what I'm talking about. And yes, most here would suggest taking it to another Mazda dealer in Toronto (I take mine to Whitby), but I really have zero time for that. Making an appointment at Whitby is already hard with my schedule. So that's why I've been keeping track of mileage so I have something to put in front of them so they don't brush me off. It's easier to prove with paper :)

[Xerox]

I make it a habit of monitoring my fuel usage using the method described by WW (writing down distance after fill-up - I always stop at first click).

I got the car new in April 2005. Data for January 2006 is missing.
MPG US (I grew up reading American magazines and most web sites use this measurement so I find it easier to compare)
2.3L Hatch, MTX, no mods (I run winter tires and rims)

It does appear that fuel consumption is slightly lower in the summer.

Well obviously you've tried the proper things and its a good thing that your keeping records, as for the battery suggestion its basically to clear your computer of stored parameters set by your style of driving from day 1, ...its pretty simple to do just disconnect the battery for approx 20 minutes and while its disconnnected have the ignition switch turned to the 'ON' position this should clear the parameters and you'll start with a clean slate.If nothing changes then I would suggest taking it back to the dealer (time permitting) and don't take NO for an answer.It is not normal for your vehicle to get mileage like that and there have been several members here that have had thier situation remedied by either a Flash of the ECU or having the Purge Valve replaced.

Good luck and let us know what happens.

just an FYI but the faulty purge valve had no adverse effects on my fuel economy.. just stalled the car on random occasions..

the ECU flashing on the other hand, seems to have helped abit but i still think it's juts a placebo effect since i'm getting about the same mileage as i was before.. (well into 2nd tank after the fix)

First of all, you are not the only one that has had a purge valve replaced and I was not thinking of your situation anyways.The info was gathered from this and other sights where the purge valve was sighted as the culprit and from my experience with other vehicles.The ECU flash is a no brainer in this situation as the computer will control almost all aspects of fuel usage and this also has been stated to solve the fuel consumption problem in some cases.So basically it comes down to the old "Process of Elimination"....tire pressure, air filter, fuel filter, gas, gas cap, oil,... then the most likely culprits after that, which are the sensors, purge valve and ECU.....Since she has taken care of most of the above its just logical to check the rest.Its basically a computer check which can be done by a competent technician in just minutes with the proper equipment......so there lies my reasoning.

[super_vixen]

Well, took my car in for regular maintenence and winter tire change, etc. Had quite a list of things to go over, main one being the mileage. The battery thing didn't work at all for the mileage over the last 2 tanks, but at least I tried.

The second I mentioned it, I hadn't even finished explaining, the guy was all over me saying it was winter still, I'm running on tires with more aggresive tread, if I go over 110 on the highway it runs the fuel down faster, it's not a big tank, yadda yadda. I could barely say that I've been monitoring this for the better part of a year and my mileage is still shit, spring, summer fall or winter, no matter what treads are on my car and no matter what speed I do. Basically I'm a girl and they don't give a shit, or they just don't give a shit period. I had all my receipts there for the past 3 months, but it was useless.

Either way, they said they'd "take a look" but I doubt they bothered. The guy said, run it on the summer tires and see if it improves, and tried to be on my side saying he's battling the same thing, and yet when I said I'm lucky to see 350km off a tank to 2 of the service guys, they did a double tank...yet went right back to defending the weather/tires as the culprit.

I'm fed up. It's ridiculous that I can't get 400km off a tank unless it's 100% highway driivng....I'd gladly go back to my Toyota or even one of my GM cars cause at least I got 500-600 off a tank then.

Any suggestions of what to do from here? Do I bother to take it to another dealer? Do I contact Mazda Canada if I feel that this is an issue that should be looked at?

[S.F.W.]

I would do both. Take it to another dealer, as well contact Mazda Canada. Mazda can push the dealers to do a thorough inspection, and investigation.

The more people you talk to the better your chance is at getting this resolved.

[Flagrum_3]

Well, took my car in for regular maintenence and winter tire change, etc. Had quite a list of things to go over, main one being the mileage. The battery thing didn't work at all for the mileage over the last 2 tanks, but at least I tried.

The second I mentioned it, I hadn't even finished explaining, the guy was all over me saying it was winter still, I'm running on tires with more aggresive tread, if I go over 110 on the highway it runs the fuel down faster, it's not a big tank, yadda yadda. I could barely say that I've been monitoring this for the better part of a year and my mileage is still shit, spring, summer fall or winter, no matter what treads are on my car and no matter what speed I do. Basically I'm a girl and they don't give a shit, or they just don't give a shit period. I had all my receipts there for the past 3 months, but it was useless.

Either way, they said they'd "take a look" but I doubt they bothered.

Jesus...I would have laid it into that jerk for talking like that and treating you that way, man that burns me when they pull shit like that, maybe next time bring the other half with you and ask to talk to the Manager and don't loose faith in your Mazda yet because That is not normal mileage for this vehicle and there is obviously a problem.Try calling the dealer manager first before you contact Mazda because Mazda will just tell you to do the same.But briefly let them know the situation and that your not satisfied at all by the way you've been mis-treated.

Keep us posted and good luck

damn .. I do 400-420 with a full tank ..

[Garu]

Thanks to majic's sheet I'm starting to keep track of my mileage. Last night I filled up my car for the first time. Mazda filled up my first tank which last for about 370km until the light came on. I didn't wait until the meter bottoms out because I was afraid running out of gas in the middle of highway.

Inputs from other MS3 owners will be appreciated too. I want some comparisons.

[ng3]

I've read thru all 5 pages just now and people should really take into account the engine difference between GT's and GX/GS...
Last time I talked to a GT owner I heard of 11 to 12L/100km. I have a 2.0 Auto, and over the summer the average was 6.8 to 7.5, now over the last few months I've been getting from 7.5 to a Max of 8.8l/100km.
Max on a tank over the winter was 590 with the light just coming on...

Also counting at half tank is not too accurate as other people said...

As a side note the Gas Warning Light comes on when there are 12-13 litres left in the tank. So 50km for sure, 100 you're risking it...

[ng3]

I just finished changing most of the things that can affect the mileage like Spark Plugs, Oil, Air Filter and Back to all season tires and a bit of injector cleaner, and on the first tank I got 659 km, with 11l left in the tank which gives about 6.9l/100km... Can't complain... Ok, the warning light came on at 609 km.

[faibs]

mostly highway?

[majic]

don't forget ng3 has a 2.0L engine so his numbers will be different from what the GTs and hatches get..

also.. his might be 5MT

[zoomette]

wow I'm lucky if I get anything close to that...then again
standard would help....450 for me

[stealthman12]

I used to get round 550-570 to a tank but recently its been around 480. Maybe because of the winter tires. i'm not sure how accurate the trip is sometimes because i've run at least 30 km when it says 0, which i knoe isn't good for the car but i think the trip just gives u a warning telling you that you should fill up but if u can't u could probably go a bit further.

[KenYork]

I drive a GS. Through the winter I got about 500km/tank. Now that i'm off the winter tires and back on stock I'm getting over 600km/tank. Mind you my car is also not idling as high to warm up as well.

[super_vixen]

Well I finally called Mazda Canada after giving the car a month with warmer weather and summer tires (aka bull shit), and lookie there! The gas mileage hasn't changed! Still lucky to get 330 off a tank.

Mazda Canada won't do anything for me either. I have to take it back to the dealer where I was treated like shit and brushed off...I have to tell them I spoke to someone at MC and say that they need to check my car for any mechanical defects that may be causing my bad mileage....and if nothing is found, then I'm SOL. They won't replace or repair anything unless they find due cause. So if the *******s test drive my car and look at it and say "oh everything looks normal, sorry nothing we can do", I continue to drive my gas guzzling car with gas prices of over $1.


Not to mention the guy started to tell me that "there are so many different regulations for gas consumption from the government guide, blah blah blah." Yeah...I know. I understand how variables work. But to go from getting over 500/tank to getting under 350...that just doesn't seem right, now does it?

I love my Mazda, but trust me...I will gladly go back to Toyota or GM in a second if they don't fix this. I am beyond pissed right now. I swear the guy on the phone at MC didn't even give two shits about this.

[Flagrum_3]

Maybe you should take the car somewhere else to have it evaluated.Do you know anyone who is a mechanic that can help you?....or maybe its time to write a nice story to the Toronto Star explaining your dilemma with Mazda's service and support! (Or maybe just threaten doing so)....even with no dash light coming on they should be hooking the computer up and taking a drive, that's the only proper way for them to find the problem considering your complaints and if they are not doing so, than they are just asshats!!

[super_vixen]

The car has to be taken to a Mazda dealer regardless. Even if a 3rd party proves there is something wrong, the Mazda dealer has to be shown such things in order for things to go through warranty. But no..I don't know any mechanics well enough to take my car to.

I was told I may be charged for tests or repairs if they prove that something is wrong, but that it doesn't fall inside the warranty (which I'm still under for another 3300km). I think that's just insane. If I've followed all of their suggestions for fuel consumption, and my car hasn't had any other issues, I find it hard to believe that regular wear and tear would cut my mileage in half (therefore voiding my warranty).

I'm also angry that despite me asking for my car to be checked over the past year...there is no obvious record of this because they have never hooked my car up, so it's not on any work order I have. Plus the person I drop the car off with, is always different from who I pick it up from. Cross-communication is useless when you want to know what was done or not done. Calling them has done nothing more than what has happened in person either.


But yes...asshats they are. I'm going to call and book my appointment tomorrow (which will be the hardest part). But I agree...if things aren't looked after, I will be sure to follow-up with other options.

(ok, I'm done ranting now)

[Flagrum_3]

Vixen, next time they say something like that to you, tell them to put it in writing (for your records)....What a bunch of lying motherf-----s.Don't listen to them, Of course if they find something wrong like a sensor they 'will' have to replace whatever under warranty and the cost of finding the problem should be covered also.With just 3k left on your warranty I would strongly suggest you don't take no for an answer.

.

[super_vixen]

Of course..the service manager is never in when I phone.

Bringing the car in on Friday and the guy was already giving me a hard time because he doesn't know if he'll "have time to get it done".

The guy on the phone asked me what it was regarding, which I said my gas mileage..and he instantly jumped into the defensive. Can just ONE person not jump down my throat regarding this? Do no car dealers/service people have compassion? You'd think I was asking for a brand new car. I just want it fixed. I want to be able to get 450-500 again. That in itself would be amazing.

I have no idea what I will do if they come back on Friday telling me that nothing is mechanically wrong with it. I just might snap.

[MattC]

from day 1, my 07 GT has had bad mileage, and its only gotten worse kinda my fault cause i read about it before i bought it, but god damn, such a sexy car, its tough to be mad at it.

all the stories I read on here make me not want to try to do anything about it either. You would think they would work to fix it, but i guess they figure people will just buy them regardless, and by that point, who cares if their happy.

[Flagrum_3]

I've said this before and I'll say it again; if people are not getting atleast 500+ km/tank and all things have been checked ie; driving habits, tire pressure, air filter etc; than there is something wrong and the dealers cannot just shrug you off.....Get MAD and ream them if they won't help, demand to see the Manager etc;, etc; and Vixen you might just have to take it to another dealership if that one does nothing.I know you live in Oshawa but Ajax Mazda or Pickering Mazda or even Scarbro Mazda are not that far away and I don't see you having a choice considering your nearing the end of your warranty.

ps; Vixen, please let us know what happens from Friday.

which dealership do u keep going to?

what is your exact mileage in L/100KM?

[-RJ3-]

I'm currently at westowne and they are replacing my intake manifold under warranty.

This is the cause of poor fuel delivery. My existing intake's butterfly flaps aren't functioning
Properly. So they will replace it.
I will also get a fuel injection service wen I get the intake manifold replace.

I will update you guys later

[alau]

I use a different way to measure gas consumption and find it more accurate then simply looking at the gas gauage.

After I fill up (...almost till it spill) everytime, I reset the trip km counter. Then next time before you fill up, look at the km you have driven and divide it by the total liters of gas you pump till the top. This way you will get a pretty good estimate of your gas consumption.

A few of us here track it regularly.

As of right now, my average is exactly 10.00 L/100km.

Well filled her up tonight at Shell and I got lucky they were out of regular and mid-grade, so I got the Premium for $1.029 L, ...btw the premium or V-power as they call it, has 0% ethanol.So I'm curious how this tank will do! But anyways it took 45.3L at 585.6 km... I believe that works out to 7.75L/100km or 36.5mpg.I'm quite amazed as that's the best I can recall getting, ....I wonder if the new exhaust has anything to do with it?

nice... with downtown driving and stop and go traffic the light has been coming on at 520km for me (shell gas) but i usually get about 280km to the half tank mark which makes me believe even more strongly that the gauge sucks :chuckle

[faibs]

do you guys have the 2.0 or the 2.3?

[majic]

2.3 for me and MK.. i think flagrum too

thats honestly incredible, good for you. im happy to hit 200 at the half way point.

[Flagrum_3]

Faibs, mines a 2.3 with a Vibrant cat-back, no intake installed as of yet.And Majic yeah I don't rely heavily on the gas guage for accuracy, its just a guide I put emphasis more on the calculations which are about as acurrate as you can get considering all the variances.

[Voodoo]

yesterday i went to the meet from Guelph. I did a test on cruising (on straight flat road sections).
at 100km/h my info computer read 4.4L/100km
at 120km/h it read 6.4L/100km
its a big difference
im sure anyone can hit 700km per tank by doing speed limit. but 100km/h is slow as hell on 401, it seems like the whole province population passed me in a 30km long hw section

[MAZDA Kitten]

Flagrum... just an FYI I remember posting when I had my Vibrant installed i noticed an increase in fuel mileage

[super_vixen]

So, went to the dealer about 2 weeks ago now. They said the only problem they found with the car, was a loose "cap" (or something) near the o2 sensor (I believe this is what the service guy was talking about), which apparently was causing air to get into my tank, thus lower gas mileage. Otherwise, the car ran fine on the computer, and they found no other mechanical defects.

I'm now on my 2nd tank of gas since then. First tank, was about 100km MORE than I usually get (I filled up at 420km, and the light had been on for about 20km by then). It's better than usual, but I'm still not 100% satisfied. But I could see that the needle wasn't dropping as much as normal.

However, this tank I'm currently on...I'm almost to half and I doubt I'll even hit 200km. It's like I can WATCH the needle dropping rather dramatically while I'm driving (and no, we're not talking excessive speeds or a/c or anything). I can't see me getting 400km off this tank...by the way its going...I'll be lucky to hit 300.

My last resort will be going to another dealer (not sure where yet), and attempting to get a 2nd opinion. If that doesn't work, the car is gone.

I haven't had time to enter all my gas receipts for proper numbers, but I'm going to do that as soon as I have time.

[MAZDA Kitten]

:bang
so the battle still continues

[-RJ3-]

Vixen,

They didn't find any problems with the valves opening? I complained about fuel mileage, and they found that problem out... They are going to replace the intake manifold next Monday.

You didn't hear anything strange around the manifold?

Hope this helps you out.

[Flagrum_3]

Here is my recent tank-fill numbers.(This is with the Shell V-power premium fuel) 525 km driven, 40.4L used...If figured correctly that gives me 7.7L/100km. or 36.5 mpg.....looks like using premium made no difference!! numbers are about the same but the car didn't feel as peppy! Wierd!!


_3


.

[Wild Weasel]

That's not really weird. Premium fuel doesn't provide more power. It simply resists detonation to that the engine can do things that provide more power that it otherwise would not be able to do.

If an engine isn't made to do those things, then all you've got is slightly less explosive gas.

To clarify; I was not expecting any improvement in performance, I was expecting my fuel consumption to be worse, but I'm suspecting the lack of ethanol in the Vpower fuel helped...But like I said, I sensed a slight decline in peppiness, which I would suspect is from the slower burning premium fuel.

How do you calculate all that
I have my receipts from last two fills up and how much I drove

[majic]

use my spreadsheet ya mofo...

or if you want to do it just once (cant get a trend/proper avg) then use this

Liters/100km

(liters filled / km driven) * 100km

i've been keeping track since day 1.. and i can tell u it's NEARLY impossible.. and you do NOT drive 140kph on the highway.. lol.. i drove past you @ like 110 and you do onramps below the posted 'suggested' speed limit :P

Hey Faibs, may I suggest that several tank fulls before your next oil change, add some Fuel injector cleaner or fuel system cleaner to your tank...FYI, I use Redline which you can purchase at any CT.This basically will help clean any carbon deposits left by any poor gas and also which happens normally and then remnants will be flushed out with the oil change.I do this every oil change and I acquient this partially to my good fuel economy.

I usually use Mobil1 but my last oil change I switched to Royal Purple, just wanted to try it out.But I'll be sticking to Mobil 1 from now on....just a personal preference....not saying you should use it but definitely helps to switch to synthetic if you haven't already.

i switched after first 2 oil changes so at around 15-20K

I switched to Synthetic at around 80,000 i believe
Its never too late but better sooner than later

[MAZDA Kitten]

add some Fuel injector cleaner or fuel system cleaner to your tank.

I've only done this once like 50,000km ago
Is it recommended to do this more often? I had no idea....

And where can one pick up Royal Purple?
Does MOTUL make 5w20?

Use fuel injector or fuel system cleaner once a year or so.

Faibs; I changed to synthetic at 16k if I recall correctly and I use SAE 5w-20.

MK; I picked-up the Royal Purple @ Performance Improvements, as for the fuel system cleaner, I don't think there's any "solid" recommended time, but I would suggest putting some in before every second oil change, (atleast). Also with the Redline, I find it works best when I use (1 bottle) in 2 or 3 consecutive tank fulls, leaving more for the last tank.

i would consider that good, but depends on the conditions

city or highway mostly? at or mt?

520 off a full tank basically is not enough info for anyone to answer your question! List the amount of liters you used , and the type of driving ie; % of city/hwy driving, auto or stick?

THis is what I do....I just switch to the fuel mileage reading that has never been resetted, and then fill up when I need too... The way the gas is going these days, its not a win win situation.... Everytime i monitor the mileage, its like a sore thumb 300 mid!!!!!, I'll just be happy looking at the un resetted fuel mileage at 500 on a middle tank LOL!!!!

Update AGAIN:

A member on the forum here put me in touch with the service manager at Scarboro Mazda. I spoke with him and he said to bring the car in and they'd see what they could find/do.

I made an appt. for Friday (I work 2 jobs and have a child, so getting time off to GET to Scarboro when they're open isn't easy)...I took the day off work, drove in for 11am. I knew the service manager wouldn't be there, but he had spoken with a service tech who would be, and he knew everything that had to be done, etc.

I arrive and find out the service tech isn't there. And no service manager (which I knew), and no one else there knows anything about my car/issues. The guy said "well you can leave it here, but we don't know what's going on".

Wow..thanks for that. I just took an entire day off work and wasted my time/gas driving out here to find out that you're all as incompetent as the other dealer I go to! (And this has nothing to do with the member who referred me whatsoever, I'm just angry at the dealer!).

Now I can go back to that dealer and take another day off work to hope they show up..or I give up....why does Mazda hate me so?

Yesssss

I picked up LUCAS though

[Flagrum_3]

Just recently, turned 50,000km on the odometer.Latest tank full 490km @ 39.96 litres works out to 34.4 mpg (CAN) or 8.16L/100km....For the whole summer (last 12 tankfulls)averaging 7.99L/100km.....
not to shabby.

(Mobil1 5w-20, orig oem filter, Shell reg)

My last fill up.. I did 554 kms,
and it took 42.23 Litres (at first click-off of pump)

if I'm calculating properly.. I think that about 7.62L/100kms

it's gotten better with each fill up so far

what size motor? auto or stick? all highway? if so what average speed?

Well based on his sig pic he has the sport. They only come as a 2.3 L.

[garboui]

so far this summer i have been averaging pretty much a constant 8-8.2l/100km with auto tranny and 2.3L engine; most driving was 60/40 highway/city.

there were a couple in there when i was more highway ~110-115km/h that i had ~7.7l/100km. recently 2 fillups ago i had an all new record at 7.23l/100km. allthough that can probably be attributed to my drive into work now on back country roads averaging ~80km/h. last fill up was bad though at 8.8L/100km but its prolly due to me enjoying my back country commute in the last week. lol

[Flagrum_3]

what size engine? auto or stick?

2.3, 5-speed, 70/30 city/hwy, normal semi-spirited driving.:chuckle

I've finally come to the conclusion why gas mileage has decreased. CAI installed, and yes I gun it every chance I get, and uneven tire wear.

After having an alignment done, new tires and running back to stocks.Driving at a normal pace without gunning the car has gotten my gas mileage to improve. I have filled the tank at 473 with the fuel empty light starting to come on. Before that it was about 450.

I didn't calculate my mpg though

[whiteomega]

remember that there is still a short filler neck between the gas cap and the tank, and if you fill that with fuel too, it could skew your numbers.

i generally fill until the pump clicks once, then stop and measure my mileage from there. i just reset the trip computer (but not the ecu) after putting in my exhaust; i'll post here when i have some numbers. the last fill up was bang on 10.1 L/100 km (pre-exhaust) with spirited driving, 80% city.

[garboui]

NEW RECORD -- for this weekend. i dorve up to montreal on friday, filled up on my way back just outside quebec, 7.1L/100km. ave speed 110 - 115km/h; this was on petro-can gas. on the way back i only managed 7.5L/100km. possibly because of the shell gas or my increase in speed average of 115-120km/h.

there was alsom a 7.3l/100 before these two as well, but the previous two are 100% highway with an atx.

[bubba1983]

been constantly getting 550km now per every tank of gas for a loong time now

[ottawajoe]

Make sure your heater controls are not set to any defrost cycles. Pur the air to feet or face. Your fuel mileage will improve 1-1.2 litres every 100 kms.

[lamerking]

Right now I'm at 260km through half a tank. I have the autostick and going through manual. Technically I should hit 500km but it seems to struggle around that mark

[bubba1983]

agree, 2 main things i changed over the last year that boosted my mileage to 500+km a tank constantly....changed the heat controls to your face and all in town driving shifts were done at 2000rpm

[bubba1983]

not sure about the science behind it, but i find i was gettin constantly less than 500km, more towards 450....made those few changes, and it improved considerably (2.3L sedan, header, cat back)

mind you, i constantly fill up after the first click...some argue not the greatest thing to do, but i do it anyways...

EDIT: keep in mind with the colder weather approaching, your mileage will go down drastically....nothing you can do about it anywyas

[qycxzerqp]

Hi, new here. I want to know if anyone hit 500km one tank? All city driving, no highway. Thanks.
