I've had my 09 Fit Sport for about a week and a half and my first tank of gas only averaged 21.5 miles per gallon (about 70/30 local/highway). I keep watching the gauge, waiting for it to shoot up! Should I be concerned or is that typical for the first few tanks?

Thank you!!

 

don't worry about iti had 26mpg on my 2008 fit right when i bought it frm the dealer it had low few mpg during my few fillups. but sooner from breaking in, my mpg increase to 36-38mpg. so don't worry too much. it will improve in time. the piston rings need to settle in, in order to run smoothly and i mean smooooooothly.

 

Mine has been getting about 31-32 MPG (hand calculated), but with as cold as it has been here, I think that's about normal. My del sol would get about 31 MPG in the winter and 35 in the summer.

 

I was getting about 31 or 32 mpg by hand, then it dropped to 27 recently. My commute is 25 miles each way, half interstate half mixed city and rural roads. I make a conscious effort to not accelerate away from stops hard and not stand on the throttle, but I have no clue why my gas mileage has dropped. I only have about 2200 miles on the clock, Im hoping this is just part of the break-in process.

 

It also depends largely on how you drive your car, and how frequently you're stopping at lights etc. In busy city driving, chances are you're going to get low MPG because of all the stopping, accelerating and idling.

 

my first tank was just around there as well. But like RandomKoKo said, it will come up in time. I'm averaging 30+ after the third time filling it up

 

That's great! Thanks for the input, everyone!

 

that sounds low. but it depends what you mean by "local" driving. if you hit a lot of lights and never really get about 35 miles per hour between lights, your low mileage would be explainable. but add in significant highway driving, i'd think it would be higher than 21.5

i'm on my 4th tank. and i have truly learned any hint of more aggressive driving or any less highway driving will significantly cut into mpg.

the car is just flat-out more fun to drive if you're not thinking about gas mileage. and with gas now $1.70 per gallon, ive thrown caution to the wind.

my first 4 tanks delivered the following hand calculated mpg:
32.2 mpg
33.5 mpg
30.6 mpg
29.7 mpg

that includes a daily commute of 28 miles round trip. and 32 traffic lights.
and occasional highway trips independent of daily commute.

my last tank (29.7 mpg) had very little open road driving.

 

We're getting 7.1 L/100 km (33 miles per US gallon, 40 per Imperial gallon) on our car in city driving (about 60-70% on freeway) so far - not awful at all.

 

I have been getting an average of 36-38mpg from the start (this is calculated by mileage and fillup not the guage). I have a half highway half rural commute...

 

And what has the gauge been telling you?

 

Between 40 and 42, so on average so far, the gauge is always 4mpg over.

 

my 09 has 3000 miles on it 38 in town 42 or so on the highway.

 

My mpg has dropped in the last couple of fillups and seems to coincide with the drop in temperature in the northeast.
I think I'm going to leave the computer displaying the odometer and just try to enjoy the car. Alls I know is that at the lower gas prices, it takes about 20 bucks to fill up every week and a half or so. That's fine.

 

I usually get around 330 miles per tank, and it is usually around 9.5 gallons when the pump clicks off. Mostly freeway driving with some city driving mixed in. I am usually between 65 and 70 mph on the freeway. I have never got anywhere close to 40mpg and don't expect to unless I go the hypermile route, and that is just too much work. On a side note, I went through the hills of northern arizona a few weeks back, with quite a bit of 70+ mph driving with the pedal on the floor on the way up the hills, and still was around 32 mpg.

 

I haven't reset my trip meter for a few tanks now, and since I've been only displaying the trip meter, not the FE gauge. But time to time I'll take a peek at the FE meter and it's been holding at 39.6, which is great. But since I "turned off" that FE gauge, boy it's much more fun to drive! Fun to rev and like the mags say, it's like an eager puppy. Sounds good too.

 

One of the main reasons for lower mileage in late Fall and Winter is simply your air pressure in your tires. It will be lower due to the cold.

As mentioned in many posts on here....it is easy to get 40 mpg on the Fit, without driving it slow and cautiously......just keep your tires at 45 psi.

I only fill my Fit up once per month, but most of that driving is in town (a small town), or climbing up and down high mountains here in NM. I consistently get over 40 mpg.

So check your tire pressure regularly, and run your tires around 45 psi. We find our control to be better...not worse....and the old myth of the tires wearing out faster has been shot down many times in these threads.

 

unless your town has one intersection, how is that possible?

 

It's not a myth. If one increased the tire pressure. The contact patch area is also reduced (less rolling resistance). The center of the tire will wear out faster.

I wanted to see some pictures of the over inflated tire after 20K miles. There is no free lunch.

Here is an interesting article on over inflation:

Not only is that article informative and enlightening, but it's relevant. (i.e. Fit)

Thanks.
