New car so the air filter's clean..... You got me. Any extra weight in the car? Running fogs all day?

I usually over inflate the tires by about 5PSI to get a slightly more responsive ride... however with my Q Rated winters... I seem to be getting a more skiddish ride. Air filter is clean since it is a brand new car with 11.5K kms on it. Car is mostly empty except for my work computer and gym bag. I keep a breaker bar & small tool kit that fits in the emergency tire compartment.

I do hammer the accelerator from a stop at times. I am trying to be conscious about doing that less. I always let the car coast out of gear and blip the throttle to get back in to gear if i need to. Anyhow... i will try to adjust my driving habits more to be more conservative that is all i can think of.

I'm itching to put the all-season tires back on. I'm getting tired of the slushy handling from my winter tires. I also assume I will be getting better mileage too due to the lower rolling resistance on all season tires.

I'd be happy to knock a whole 1L off of each 100kms. I'd probably be saving about $5-6/tank. That's translates to about $20-25/month which could be another half tank of gas per month I'd be saving.

Coast IN gear...while coasting in gear and not touching the gas pedal, the ecu shuts off the fuel injectors until they are needed again.

while coasting out of gear, the ecu will use fuel since it needs to keep the engine running at at least idle speed

Really?? I never knew that. Good tip :)
I usually coast out of gear because I notice that if I cost in gear, the gear slows my car down.

^^ when you see a red light ahead, just let off the gas and do not hit the clutch (coast in gear) I used to think the same thing - 2000 rpm is faster than idle speed so you use less fuel at idle right? Wrong.

On a related note $54.50 this morning for a bit over 44L :(

2010 GX 5MT Sport with Gislaved NF5 winter rubber. You can see my Fuelly average below but I seem to be getting around 8.5L/100km with mostly city driving. I think this is pretty good considering the car is rated for 8.1L/100km city and I am running winter rubber and winter gas. Tires have been around 34-35PSI and I am quite moderate and steady with regards to driving habits. Should also mention I have the K&N drop in air filter. Tomorrow it is oil change time (12000 kms) and I will be switching over to 100% synthetic 5w20 (penzoil plat) and I am curious to see if that will bring me some fuel savings. Swapping the tranny oil for some synthetic Redline is also on my list of To-Do's.

You can get the mileage out of these cars but only if you drive accordingly

Sometimes I wish I had a Diesel... then again Diesel prices have been quite expensive lately. I only used the once this weekend to make a Costco run. I took TTC the rest of the weekend. Can't justify driving downtown with the price of gas and parking these days.

So I topped up yesterday night at Costco @ $1.174/L... can't believe they are 6 cents cheaper than everybody else. + I got 3% discount with my Amex

Anyhow.... I've been easier on the accelerator by a lot and still keeping the revs about 3000-3250. I averaged 8.414L/100kms this last tank. Better but nowhere near the 7.4-7.8L I was getting in the fall.

Wow, good to know!
Now I'll cost in gear :)

Yeah, i used to coast in neutral to a stop with my civic. Since learning about coasting in gear (and it's a lot safer anyway), that's what I have been doing thus far as long as I'm not geared too low while coasting, and don't let the engine bog down at any point.

Once my cdn tire mastercard 5ct fuel discount runs out on the 14th (resets back to 2ct/L), I'll be trying Shell gas and its supposed no ethanol blend at 91. How come your Amex is giving 3% discount? The Amex at my local costco advertises 2% cashback on fuel purchases.

You are correct it is 2% for fuel purchases. Costco card also earns you an additional 1% when you fuel at Costco, hence 3%. 2% everywhere else.

Not sure if a thread like this has been started before...Trying to find one would take an uber long time so I thought I'd start my own. hehe

Drove my car for 3 days, highway driving on all three days, with about 250-300 km's so far since my last fill up and I currently have about half a tank left...

Feels like my car is treating gas like water! Only difference is, water is 10x's cheaper!

To date, best I was able to do was about 560km's with just under one bar of fuel left (gas light was on at this point)

How about everyone else? :rolleyes

How many kilometer's do you get per tank of gas?

Any secrets to keeping your gas tank full with a good number for kms?

My 2010 is averaging around 425-450km a tank right now. I am pretty sure it can make it to 500 easy, but I tend to fill up asap after the low fuel light comes up. This is 50% highway/50% city. The distance will most likely improve when the weather warms up some more and I changeover to my summer tires.

Last tank was ~600km. When I got the car last summer I hit 700km. I'm sure I could hit 775 or 800 on a long highway road trip.

My secret to good mileage is rolling on 16's, and not trying to add inches with my gas pedal, lol

about 263 km per half tank, winter driving(mostly off highway). But i have a 2.0 litre 5spd manual.

Avg: 9l/100. I'd say 50/50 driving. But the city driving is done by my GF who has a much heavier foot than I.

I think they have swapped out the Winter gas. I too have noticed a significant improvement in mileage in the tank I am currently half way through. Will post actuals after I refill later in the week.

Probably depends on the station, but overall I'm getting further on less. I think the last tank was well over 600 - I'll have to see if I can reach 800 this summer - I'll carry a spare 10L in the trunk :)

My 2005 Mazda 3 is pretty good with average about 8.5L. It get to about 10 with Winter tires on. I don't do anything like jack rabbit at stop light. Best I've ever done is 675km on 42L of gas. Going to cottage country.

I just recorded 7.4L/100km and this would have been higher except for today's killer snow/ice storm which meant hours of slow stop and go crawling. This is definitely not a one location thing as I track with Fuelly and was never able to get better than 8.4/L up until this last tank.

Should also note that winters are still on and is my 2nd full tank after switching to Penzoil Plat. 100% syn. oil.

Best tank so far is 8.9L/100km.

Pretty much the same for me. Slowly starting to notice slight increases with the warm weather a week or two ago but can't get too excited over it.

I'm getting 500 kms on my MS3, and that's 80% highway. But I travel about 45 kms one way to work every weekday. Damn 91 octane prices!

I'm driving a 04 2.0 MT sedan, has 174,000 kms on it. have done several runs from TO to Windsor, with cruise at 112kph and getting consistently over 40 mpg. As high as 43.4 mpg. Still have the snows on which affects mileage, and I have a rear trail arm bushing gone that is pulling the one rear tire out of alignment. Present set up is a K&N drop-in (not noticing allot of difference) and the E3 diamond fire plugs, put in last summer.

I know that we could do this conversion, but you're on a Canadian site - and in Canada gas is sold by the litre. We measure fuel economy in litres used per 100 kilometres driven..... what's with the mpg?

All I know is that if gas doesn't lower itself soon, my car won't be seeing any km's anytime soon! LOL

Why are you running 91 octane anyways??

MS3 requires high octane for optimal turbo spoooooool!

I've got over 650kms on a tank in city driving before... but probably only once. With no bars left I can push another 75-100kms. However as I've read it is not recommended as it leaves the fuel pump dry and can be damaging.

I'm averaging 7.1L/100kms on my last tank. Way down from 9.1L/100kms avg from the cold temp driving.

Before I changed my spark plugs, I was averaging about 400 per tank.. Sometimes even less.. Now, at half a tank, I've already reached the 250km mark.. :):) Not too shabby I'd say. All city driving by the way!

i hit 121.8km before the gauge left full yesterday. will be interesting to see what i will get for the tank. its at about 204 right now with 1 bar above 3/4

I'm getting similar with my 5MT 2010 Sport GX. My numbers have been improving the last 5 weeks or so. Say bye-bye to the winter gas. :)

My first tank got almost empty on Sunday (bought the car on April 28th).

2010 Mazdaspeed 3. We did 550Km with a full tank. I think we could have gone to 575km.

9.1/100km?

I made a mistake.

8.75L / 100km.

No, when the gauge reads almost empty, it still has about 10L left in the tank, all modern car fuel gauges do this as a safety precaution. In his case it was around 12L remaining.

I thought it was about 5L. Good to know. Is this info 100% accurate?? 10L left when the gas sign is on? Does it say in the manual?

I was going by the estimate that he could have gone 575kms for the full tank since he didnt specify how much was left
