Getting the absolute most of my current tank - 389.5km on half a tank.
This was driving from Etobicoke to Owen Sound and back, and driving like a complete WUSS (anywhere between 80 - 110 with moments of 50 when HWY 10 got into the small towns. It was painfully unbearable but the cops were everywhere) in a 2.0L AT. Computer says after the trip that AVG fuel cons. was 6.3L/km. NOW....on to getting it back higher ;)

Wow guys,
Ive never heard of a car with so much devience in fuel economy. Fuel economy was one of my main concerns when I was considering a new car. Having a love for engines and technology, so what engine output. When I looked at the matrix XRS, it had the same rated fuel economy as the mazda 3. I testdrove both. More torque in the mazda, more power in the matrix. After driving it for 2 years now, even when I auto x it or bring it to the track, I have never hit below 27mpg (us) (8.7 l/100km), I dont do many long trips, so Ive only hit as high as 36mpg (us) (6.5 l/100km). I usually average around 32mpg(7.3 l/100km).
I have heard of small deviances from other XRS owners, but none as far as going from 40mpg to 20mpg.... Thats insane.
Im happy with averaging 32mpg. Especially when it put 170whp to the ground with just an intake.
Plus I tach 3500 rpm ish at 120kmph... on a 6 speed....
Some guys who have had mileage problems reccomend reseting the ecu (pulling the battery or ecu fuse)... I have not had the same luck, but if you have bad mileage, try it out. I think it may be different in our cars, because when we drive agressive, the car becomes noticably more responsive with continued use.
Latest Update...I\'ve just reached half tank mark= 328km on the trip....100 percent city driving, but I decided to drive more conservatively; gear changes below 3000rpm, very little down-shifting etc;
Psivic I use both Petro Can and Sunoco gas whichever is closer.But alas I did think of something I did that might have caused the change...I had to disconnect my battery for approx an hour to rewire my head unit, apparently when they installed my system they crossed a couple of wires :sarc ....so anyways maybe my computer cleared itself and hense some better numbers.
Several weeks from now I\'ll be taking a cruise out to Ottawa =99 percent highway driving,...I\'m curious what kind of mileage I\'ll get.

Just an update.
Filled up a full tank @petro canada.
Managed to sorta \'granny\' my driving habit and managed 615kms on a full tank.
I\'ve just been easing up on the gas since gas prices are so damn high these past few weeks.
Other than that the car is not fun at all to drive when grannying! lol...
I do about 20 km highway, 10 km city every day for work.
i get mmmm 473km and the needle is low but the light has not turned on.
=(
even when granny driving this is what i get.
when the light comes on @ around 480ish that means you are doing about 8.5-9L/100km which is pretty much standard ;)Quote:

Excellent advice!Quote:

i jus got 640 kms on a tank
thats the most i ever gotten with this car
just broke the record for my car... did 690km on 46.8L of gas... the lights turned on and i gave it anther 30km.
Driving style is very easy... and 90% on hwy (will be 120km/hr)... even local, it\'s 80km/hr~ (road limit, so ppl usually do 100km/hr)

HOLY MOLY.
Enough said.
There is NO WAY you are getting 35 - 39 MPG with a 3.

My measurement process so you have no doubt, as I can assure you, there are no problems with my measurements:Quote:

Reset trip-meter each time I gas up (fill tank completely).
Write on gas receipt the number of kilometers to that tank (volume of fuel).
Take receipt home and enter into fuel log spreadsheet.
fuel economy = (volume of fuel x 100) / # of kilometers driven
This measurement is sourced directly from Natural Resources Canada\'s Fuel Consumption Calculator.
http://oee.nrcan.gc.ca/transportatio...ut.cfm?attr=16
Now to describe how I manage to attain the higher than normal (for Mazda 3 owners) fuel efficiency, I:
- live in a rural area (cannot stand urban areas - something to do with a higher % of idiots)
- travel 30km to work, 3 stop signs on route
- travel an average of ~90 km/h
- make efficient use of car travel in urban areas (read above)
- drive a manual transmission car
- I\'m easy on the accelerator
Getting the results I have is not rocket science but just driving with fuel consumption in mind. That isn\'t to say I don\'t enjoy my car and the fun that can be had with it, I just choose my times when the road becomes curvy. For the record, the 39.1 mpg I measured for April 7 still boggles me, but the numbers don\'t lie.

taken about a month ago.
should mention that most of the km are highway.
Was driving in Montreal this week and a tank of gas there doesn\'t seem to last as long a tank here. 2 tier gas. The stuff they get sucks.
The roads in Quebec are also absolute rubbish.
Yup, I couldn\'t believe how bad there were the last time I drove down to Montreal.Quote:

Just read today in Consumer Reports that rates fuel economy Mazda 3 sport.
I assume it\'s for auto tranny.
City 13.9/100
Hwy 6.7/100
Overall 9.5/100
On the side note they also have numbers for Audi 3 and Saab 9-2X that pretty close to Mazda 3 numbers.
^^ but both of those need premium
The Mazda3 sedans get better mileage simply because they weigh less.
Also, MazdaKitten - I\'m not sure how much you weigh, but I\'m assuming it\'s not much? That kind of weight savings could add up over time towards mileage.
lol.. i hope you did not just call her phat ;) or there\'s gonna be trouble.. lol.. but i can tell you that the weight savings would NOT give her 100km more per tank..Quote:

Back when I was in driving school classes (LONG time ago), my instructor said that every 100 lbs consumes 10% more gas.
No it wouldn\'t I agree. It would give her a very slight advantage in the long run if she weighed 90 lbs though LOL. The bottom line is that there are 4 major factors - the amount of lead foot, the amount of highway driving, the transmission, and if the car is in tune.Quote:

Well you do make a good point... if I weigh about 100 lbs less than an average guy then I can see it over time. I thought about that too.
For example. Last night my bf and I drove to Milton from Sauga with 4 rims in the back seat. The car felt so sluggish and today i hit half tank and it was 325 (usually it is over 350). Just a slight decrease but the weight had a lot to do with it me thinks
The problem is that the mileage is rather poor if all your driving is city or stop-and-go, whereas if you can stick to just highway it\'s actually quite good IMO. For me, a tanks worth of city driving will net me around 450km before the gas light goes on, whereas a tanks worth of highway driving will get me no less than 600km before the light goes on.
Also, if there is a difference between the hatch and sedan, it is very, very marginal. In a year of owning both types I have yet to see a difference.
The last dozen or so tank-fulls I am averaging 34.6 mpg(imperial measure), almost all city driving.
When on occasion driving highway, I get 36 mpg.I have a Sport GT 2.3, I don\'t baby the vehicle and my highway speed is 130kph@3600rpm on average with spurts to 160kph:D.
My stereo system adds approx 30kg to the weight of my vehicle and I\'m no slimjim either.So what I\'m trying to say here is...for those people that are concerned about lousy fuel consumption either try different fuels, reset the computer or use fuel injector cleaner periodically.If these things don\'t help take the vehicle in for a check....200k for half tank seems excessive and I would think that that is a BIG SIGN there is a problem and with the price of gas its also alot of money being burnt away.As we all know these cars don\'t all come from the factory in perfect condition and it would not be out of the ordinary for something to be out of whack and to cause poor gas consumption.So take the car into the dealer, don\'t let them tell you its \"normal\" and demand a full diagnostic.

AMEN!!!
Been there, done that! (gone to dealer for diagnostic) They found problems, and now I seem to be sorted. Just experimenting with different levels of octane now. Wanna see if lower octane (I like to run Ultra 94 (don\'t want to hear it!)) will get me more clicks.
94 Octane-City/Highway Granny driving: Approx. 450 km\'s (at reserve)
91 Octane-City/Highway Granny driving: 470 km\'s (at reserve)
87 Octane-City/Highway Granny driving: 470ish km\'s (at reserve)
:D
Okay, okay, yer all right...I guess I\'ll start running 87 and just putting some STP in the tank every little while.
Most likely will... I run 87 and I get about 550-580 kms a tank.Quote:

Don\'t you worry about running 87 octane? I mean down the road? I\'ve seen cars with gunked up injectors, engine knocking, and all kinds of other problems from using that gas. I wonder if that\'s why people need injector flushes and new injectors after a few years?:(
I guess it\'s o.k. if you\'re leasing, or not planning on keeping your car for a long time.
I\'m just leery of going that route since I intend on keeping my car for a while.
Anywho, don\'t mind me, I\'m just thinking out loud.:D
Thanks for the input!!!
your car was MADE to run 87 :sarcQuote:

go read the manual.. and hand over the 5bux/tank over to me.. thanks!
That\'s what they SAY, so you can keep coming back for extremely expensive service. Makes you wonder why these new cars don\'t have long shelf lives, eh?
I\'d rather use the $5 for Timmy\'s, thanx.
Anything above 87 Octane is a waste of money unless you have messed (f\'ed up in my opinion) with your timing or are running boost (supercharger, turbo). 87 will not gunk up your injectors any more than any other octane. I don\'t know where you heard that! Older cars sometimes have to switch to higher octane because they have carbon build up that results in engine knock. Higher octane helps curb engine knock - hence why some older engines have to switch to higher octane. The fuel itself is not the reason for carbon build up - inefficient cylinder explosion is (i.e., rich condition). Newer cars are carefully regulated by computers and if taken care of will not build up carbon like older cars. They are pre-programmed to burn the fuel as efficiently as possible. Carbon will build up over time - but not quickly. That is why we get carbon flushes once in a blue moon....Quote:

No matter what kind of gas you run, whether its 87 or 94, clogged injectors will happen. As far as engine knock is concerned, well that comes from using the wrong type of gas (87 on a 91 engine). Its a fact of life with gas powered engines.Quote:

You could run 91 on your engine if it makes you feel better, but you will be spending more money.
I guess I\'ve been burnt one too many times. I must have been driving the wrong vehicles. This can make me a little bitter...
I know you guys know what you\'re talking about, which is why I keep reading.
Thanx for the tips, guys. ;)
Hey sorry hope my post did\'nt sound preachy. So why not mention what problems they(dealer) found?Quote:

91 Octane-???
89 Octane-???
I\'ll let everyone know (hopefully you care!):D
Would be informative to the forum!
When I mentioned trying different fuel I meant Shell or Sunoco etc; using anything other than 87 octane is a waste of money and in some cases its worse to use higher octane.( I find Shell gives me better mileage)
Injectors and combustion chambers will carbon up eventually on all gas vehicles, but it shouldn\'t effect anyones car till way down the road and it can be postponed by using injector cleaner every few months and maybe every 100k getting the injectors and system proffessionally cleaned.My second car, which I\'ve owned since 92\' is fuel injected has over 300k and i\'ve never had a problem with injectors or carbon build up ie; Knock and have used nothing but 87 octane.
just some thoughts...

I am praising Joe for the new MS Intake. Even after revving and being hard on the pedal ever since I put it on, I somehow managed just over 300km in half a tank!!! I\'ll post more realistic figures when I get some as this might be a fluke, but WOOOHOOOO an intake and good gas milage? SWEEEET!!!! :D
No worries! You didn\'t sound preachy at all, you were just giving some advice.Quote:

I have a memory like a siv ( not sure about the spelling ), err, bad memory. Will have to check my records on exactly what was corrected. Will update post.
