New owner (2 weeks) of an '08 black fit.

Got 31 mpg on first tank...purely city driving. Took it on a 1000 mile roundtrip for Thanksgiving...2 little ones in the back and full luggage...and averaged 34 mpg.

Absolutely loving this car so far.

Three months and no one has added to this? For shame, ecoFits.

I just went back through all my gas receipts for my tax return, and based on that and my current mileage Im averaging 30.5MPG. But I generally drive like a maniac. I've gotten a few 40MPG tanks on road trips though.

I thought that I would share some knowledge with you. Here is the way process analysis works (which is what we are doing with the fuel mileage tracking).

In order to establish a "base line" there needs to be at least 25 observances (fillups). Depending on how far you drive this could take a year

Once you establish your base line, then you can determine your "mean average" by taking all 25 fill ups, adding them together, then dividing by 25.

Once you get your "mean average" established, then there is what's known as a "standard diviation" (plus and minus). This varies by the observations but as a ball park figure is roughly 1.5% of your mean average.

What this means is that if your average over 25 fillups is 29.7mpg, then the standard diviation is 1.6, your range for milage is then 28.1 to 31.3.

If you get a milage figure that is outside the norm, (like for instance 40 mpg or 15 mpg) you need to analyze why that happened. Once you have determine why (high tail wind, 3 hour idling time, etc.) then this observation is removed from your running observations.

Another quick note, if you discover 5 or more points going higher or lower, then this is pointing to a "trend" and it would be a good time to analyze what is causing it.

Hope this helps
Where did you obtain this info??? Although statically savvy is it reliable?

Here's my first 5205.2 miles of driving:
Gallons Miles Tank's MPG
9.423 297.50 31.57169
7.938 273.90 34.50491
9.566 332.90 34.80033
9.092 298.70 32.85306
9.195 309.00 33.60522
8.923 324.40 36.35548
8.469 315.80 37.28894
8.799 316.80 36.00409
8.613 323.00 37.50145
8.421 313.10 37.18086
9.405 345.20 36.70388
9.002 352.70 39.18018
9.980 386.40 38.71744
8.287 324.00 39.09738
8.845 335.30 37.90842
9.036 356.50 39.45330
Just adding up the total gallons and miles gives: 142.9940 gallons over 5205.200 equals 36.40153 miles per gallon.

Finding the mean mpg of the fillups listed above gives 36.42042 mpg with an error on the mean of 0.5751547.

Either way it looks like my lifetime average is 36.4+-0.6 mpg.

I'd love to hear what the 40+ mpg group is doing to get that kind of lifetime mileage.

My FIT is a general daily sales car w/ minor mods....been averaging 33 ish. As stated above it also depends on the conditions such as winds, rain etc.
GREAT POLL!!

It"s my CAI I just like the way it sound and it hard on fuel economy. I am stomping on pedal to much..

Well, I have just hit the 6k mark on the clock. The only thing I have changed on my Fit Manual Sport is I installed an HKS Super Hybrid (drop in) filter. I just filled my tank and did the math and I got 36MPG all city driving! There was some inconsistent driving patterns though, I started to practice hypermiling the last half of the tank.
It takes practice and getting used to but I find my self less stressed in traffic because of it. I am trying to achieve 38MPG but I'm impressed with 36. :-)

I wouldn't take statistical advice from someone who can't spell "deviation". Much less one who suggests you calculate your standard deviation by multiplying the mean by 1.5%, especially when the tools to calculate it are built into your spreadsheet.

average

I am in that survey....one of the few getting 41-43 mpg. Someone, maybe many, are wondering how it can be done.

Since we live in NM, and do some town driving but mostly highway...it makes sense to me. Also, the dryness here and the high altitude (7500 ft) seem to be a huge factor...even though I have to climb high mountains to get home each time.

And also interesting to note - we burn only 86 Octane out here for regular gas. Our Fit runs perfectly on that. We have 2200 mi on our Fit.

I am convinced that we will get 45 mpg on a trip, without A/C and not carrying a kayak or two....but likely in the Fall of the year. The only mod we have made is that we are running at 45 psi, and enjoying it.

I've got 12k on my base fit (bone stock), and I average almost exactly 35mpg every single tankfull (lowest 34.1x, highest 35.9x, most right on the money at 35.1, etc)

Pretty amazing car, I don't baby it (AC on all the time, rev it a decent amount at stops, 75-80 mph cruising speed, etc). I actually get worse gas mileage on the highways

Any other non-hybrid cars even close?!

Honda Civic, Toyota Corolla, Mini Cooper, Mini Clubman, Toyota Yaris, Chevy Cobalt/Pontiac G5 XFE, Smart ForTwo, Kia Rio and Ford Focus all achieve better highway fuel economy than the Fit when driven equally.

I've wondered about some of these cars, but I just don't see any of them getting 35 mpg when "driven equally" (esp. for mixed driving)

Recent newspaper review of the civic reported 32mpg mixed driving, I don't see any way in hell the ford focus is getting over 30mpg if you actually drive the thing, the smartfortwo has an EPA rating of 32mpg highway, I've never seen any chevy get over 30mpg unless it's a metro, the minis seem to get in the low 30s, etc etc that pretty much leaves the yaris/corrolla and Rio in my very unscientific estimation, but I would guess the yaris is the only one capable of sustained 35mpg in mixed driving. . . maybe the chevy aveo too?

Your missing the data that Rich has seen when you dispute what he said. EPA is totally different than the reality of what these cars can do in the right hands. You can't mix or confuse the two data sets. The real MPG data for these cars can be found in the logs of owners. You can also do like I did and extract the data for these cars from the cleanmpg site and sort by car and look at the mean and std dev for each model. That is a good picture and data of like minded frivers tring to get the best from there cars. Until you have done that, you have no idea what the list of cars above CAN do when properly driven based on data and facts.

Cool

There are alot of variables we calculating MPG.
From my own experience w/ my FIT 5 speed;

39MPG + .....Granny Driving

30MPG.....Normal Driving

25MPG.....Flooring it

I don't think you guys are getting my point. . . I blaze around all day long, run the ac all the time, accelerate hard whenever I want and drive 80-85mph on the highway and get 35mpg every single tankful. I don't try to "get the best" from my car. I'd bet a decent amount that I'd never get the same mpg from most (if not all) of those other cars under those driving conditions.

I'm sure somebody driving a V8 chrysler could "get the best from their car" and milk it for 28mpg, but that's not what I'm talking about. . .(!)
