my car is 5speed, currently has 3000km on it... the best tank i ever get is only 380km for 32litre fill up... and that was the first tank, then it get worse.

all my driving are mostly city... only about 30km in that 3000km is from Highway.

i have tried diff driving style, nth improved.

any idea?

 

Is your Fit a manual or an automatic?

 

It is colder in Edmonton, so that mileage might not be that bad. You have to turn on the heat and defrost your windows every morning.

I lived in Edmonton for 12 years and it gets pretty cold there.

I got 351 Km for 32L fill up on my first tank. I live in Vancouver now, so 300km in Edmonton might not be out of line.

 

I've never got less than 400km out of a tank even in cold weather, like lately it's -20c or lower and my last fillup this morning the odometer A reading I use for gas was 450km or so which is somewhat low for me.

RPM range I use is between 2k and 4k mainly, if it drops below 2k then I'll shift down even if it's capable of still moving along easily (ie 5th gear at 60km/h). I like to keep it between 2.3k and 3.2k for "normal" driving though.. any lower and it feels sluggish trying to accelerate and any higher the VTEC may kick in. I'll shift between 3.2-5k rpm for accelerating and I also decelerate while in gear.. none of that coasting in neutral nonsense.

I only mention all this since it seems to scare some drivers if the engine goes over 3k rpm.. and they like to shift at 2k.. and keep rpm's as low as they can (cruising 50-60km/h in 5th gear).. and coast in neutral as often as possible.

Some older cars may sound like a screaming banshee at over 3k rpm but this is honda.. it's all good until you're bouncing off the rev limiter

 

wpgfit, my driving style is similar to urs... but my last tank was 300km...

 

I just registered 430km on 31 litres of fuel. I was looking forward to this fillup just to see how the mileage did with colder weather. In a nutshell, it's pretty much where it was before . . . LOL. Temps haven't been crazy cold, but it has been -5 to -15 or so and a fair amount of snow so slipping tires, heater going full, engine warm up time, etc. These amounts are roughly 50/50 mix between city and highway.

I expect that the mileage will drop a bit when the really cold temps hit, but overall, it's been great thusfar.

My car is an 07 Sport 5 speed and my driving habits are also similar to wpgfit.

 

Did you change the oil? When I got my car, it started off great mileage, then went abysmal, changed synthetic oil, it was good again. After a while i changed oil a second time, but this time with conventional oil. My mileage was high after this.

Your car may be new. I calculated using US system, and yours is 27 mpg. Although my worse was 30-31 mpg and this was uncommon. Not as bad as yours. But you do a lot of city driving.

 

at only 3000km it's probably best to wait until the maintenance minder tells you to change the oil (first time) since that first batch is supposed to have extra stuff in it for break-in(moly?).

I asked the dealership if they had synthetic and was told they only carry semi-syn and didn't recommend switching from dino to semi or full synthetic until around 30,000km.

IMO don't start worrying about mpg until after 10000km.

 

Thats still better than my 2006 Nissan Pathfinder. 16 MPG was the best it averaged. It was a 6 cylinder too. No wonder I have a Fit now

 

Yeah, I remember reading about bad mileage, but what iv'e noticed so far in 700+ miles of ownership so far is:

That first $600 miles, because of the recommeded break-in driving habits, I kept my RPMs below 3500 (not very strictly ) for the first 350 miles and averaged 32MPG. Afterwards, I fluctuated the RPM range but still stayed light on the throttle, and the MPG dropped to 28.7. Now that my break-in period is over, I've noticed that if I shift at 4500RPM, i get a lot LESS economy than when I shift below 3500.

But man, it's hard to lug along at below 3500

 

I think that's a great point Bahumut. When the auto makers advertize fuel economy ratings, I'm sure it's based on ideal circumstances. Driving a car "hard" is still going to have an adverse effect on fuel economy. It doesn't matter if it's a Fit or an SUV.

I guess the bottomline is if you want the best fuel economy, you have to give the vehicle a chance to get those numbers. You can't be shifting at high revs, taking off quickly, getting hard into the throttle, etc.

Certainly getting the most fun out of the Fit will not yield the best fuel economy numbers. But sometimes you just have to do it anyway

 

I have tried... i have tried few tanks with different driving style already...

 

Did you check tire pressure? You being in Canada, maybe the winter is affecting your tire pressure PV=nRT

 

I'll be sure to post back what my current tank will give me. It's been really cold here the last week (-27 to -33) and I can tell from the trip odometer that it's having an impact on the mileage . . . not unexpected mind you. Still better than my truck when I'd be getting in the single digits at these temps, LOL

 

the area where you live may be using winterized gas (typically Oct to April)
which will cause you to have worse mpg due to it biased to burn easier.
plus with the a/c blowing for defrost most of the time don't help either.

between summer and winter months, it is typical to see about a 2-3mpg
difference on NA cars, even more on FI if daily driven.

 

i am not sure about the winterized gas, but i do not use AC to defrost.

 

Unless you unplugged the wire, yes you do. The Fit automatically puts the a/c on whenever you put it in defrost mode....to disable this, see this thread:

https://www.fitfreak.net/forums/fit-...hlight=Defrost

 

On US Fits (and I assume Canadian too), the AC automatically comes on whenever the temp control knob is set to one of the 2 positions that show the defost icon, so you are using the AC whenever you use defrost - the manual describes this. The AC LED does not come on when this happens, and the AC button has no effect on whether the AC turned on or off when the air control is on one of the defrost settings. It doesn't look like you're using AC, but you are....

There is DIY thread on how to disable this behaviour by disconnecting a plug on to the air control switch underneath the dash (very easy to do). If you do this mod, the AC will come on only if the AC button on the dash is selected.

 

but the problem is, i dun even use the defost mod... i rarely use it...

 

If you don't use it, then what I said doesn't apply....

But doesn't the front windshield fog up on cold days there? It sure does here in Minnesota. We're talking about the climate control knob here, not the rear defrost pushbutton. If you have that knob set to either of the 2 rightmost positions, you're using the A/C......
