32 mpg is nothing to complain about. We're averaging 29 mpg mostly highway on snow tires.

I'm like Java_Fit, only if I decide to get on the expressways to mix up the driving, will I get a tank around 28~30mpg. If I stay all city, I'll be lucky to see 24. I also don't try to conserve fuel, it makes driving boring and I might as well be riding on a bus or train. I have a heavy foot and it has a brain of its own and that brain only knows 555.

I believe Polaski posted on how to remove the wire bridging the A/C and defroster, If so you can find it under threads he started on his profile page.

I guess I don't do as much congested city driving as most folks, despite that I live in the middle of one of the growing "worst traffic" cities in the US, but I still get 36-37 avg. and 42-44 on the highway is cake. Not sure what else to say.

By comparison, my old beat up 2000 Toyota Echo with 120K miles does 38mpg on the same roads.

Did I break it in incorrectly? I took it easy and did a lot of highway driving under 3.5K RPMs. Was I supposed to vary the RPMs a lot during break-in?

Any way to perhaps fix this?

You are just fine. When you consider the difference in weight and especially the 'improvements' in emissions controls your Fit is doing at least as well as your Echo.
PS the Echo might be a trfle better in aero as well. But then of course could your Echo haul stuff as well ? Or drive nearly as well ?

I'll attest to that... I spent 3 hours going from Round Rock south through Austin to Buda during the Thanksgiving Holiday in 2001 8:PM to 11:PM.... That was on I-35.

It's on page 112 on my 2010 sports owners manual under, VENTS, HEATING AND A/C..... I was very upset the salesman did not warn me about this, instead he showed me how to switch on the radio, switch on the wipers... maybe I myself was to blame... I am expected to read the owners manual from cover to cover before I start the FIT engine

What brand of snow tires do you use? I used Michelin X-ice and their fuel impact is minimal and it is pretty quiet, almost as quiet as the stock tires.

Bridgestone Blizzak LM-25's. They're not LRR. They are pretty quiet, and do decently in the snow.

If the Fit's driver cared to slow down, we'd do better on FE. It gets driven quite quickly, with no regard for FE. So 29 with the driving style it's seeing is pretty good.

I'm in the same city. I avoid most traffic congestion by going into work early and leaving before rush hour.

I'm averaging 36 mpg.

For comparison, my 2009 MT average is 33 MPG over 16 months/16k miles. (That's calculated real-world mileage on E10 gasoline.)

Mileage sounds right. I live in San Jose and get about 33. I could get 40+ but only coasting back from Tahoe. I think most people over estimate the gas mileage.

I've averaged 36.3 mpg over 42k in a 2009 Fit Sport MT commuting in Phoenix with the A/C cranked most of the year. I have observed that my gas mileage drops off perspicuously when there are other people in the car, i.e. I get 36+ mpg alone, but only 30-34 mpg with passengers.

Vehicles are tested on a programmed dynomometer in two 'cycles', one representing a standard trip in urban driving and the other on rural highways. They are merely a good means of comparing different vehicles as the cycles themselves rarely replicate real driving conditions but are exactly the same for each vehicle. More level driving or more hilly as well as different driving practices can vary mpog by quite a bit.

I'm still in the high 37's even with Winter here. My last few tanks have been in the mid to low 30's which has brought down my lifetime average a few notches. It also hasn't helped that my snow tires have a greater diameter than my summers and throw the speedo/odo off by 1.6% so all of my calculations are a bit lower now than likely reality. I figured it out once and was around .6mpg or .7mpg than it actually should be. If I wanted to be anal about it, I could probably go figure it out but... that's not going to happen. If I can maintain a 37mpg lifetime rating after this winter, I'll be happy... (especially knowing it should have been slightly higher because of the tires)

i'm running 185/65/15s on my sport instead of the 175/65/15 which is a stock base size. I ride about 1/4 of an inch higher which is handy in the snow and the tires were much cheaper.

Yep, thats the way they used to do it but in 2007 they added a few other tests.Detailed Test Information,

Sounds about right. I'm getting about 32-35 freeway driving at 70-80 mph. The highest I hit was when I set my cruise control at 55mph. I averaged 42mpg during that stint. I saved a bunch of gas but boy did I sure get a lot of fingers from passing drivers.

I get as bad as 20 mpg At full throttle at around 90 mph, I can actually see my fuel gauge moving ever so slowly.
 


Quick Reply: Why is my gas mileage so crappy? 32mpg, 20K miles.
