09 Fit Sport Auto
1st fill 192 miles, 4.98g = 38.55mpg, Computer said 43.2. 4.65 discrepancy
2nd fill 244 miles, 7.38g = 33mpg. Computer said 38.1. 5.1 discrepancy
3rd fill 308 miles, 8.86g = 34.8mpg. Computer said 37.4 2.6 discrepancy
 
I too am perplexed by the computer discrepency but I'm not seeing 10mgp difference. I wonder if the fact the you're filling after on 50 miles has some impact on this. My wife, who doesn't fret about these things as much, say's the computer will get better over time. I can't understand why it would change but that doesn't mean in won't. My previous vehicle-a Dodge- computer was within 1-2mpg. 5-10 or more seems like a lot, no matter how it measures.

Regardless of stories from friends, some car magazines I've read give the Fit top marks for quality/reliability but only so-so for the Versa.
 
BTW...my last manually calculated MPG for my '07 Sport Auto was 36.2mpg mosly highway with suburb driving. I've found (like most cars) that keeping the speed 65mph or less on the highway as compared to driving between 65-70 mph improves my MPG by 2-3mpg in my mixed highway/suburb driving.

2009 Honda Fit Sport with VSA/NAV in Wisconsin. Just finished off my first tank of gas and at the nine gallon mark (when the fuel light went on) I averaged 40.8 miles per gallon. No driving in inclement weather thus far. Mostly highway and I have not taken it above 67mph on the freeway.

I avg about 33-34.5 in mix driving and 39.5-41.5 on the highway driving. The MPG meter calculates highest MPG that is 80 MPG when you are moving but the not pressing the gas pedal (such as downhill or in between the highway rolls) this may result in the higher MPG numbers on your panel but that is just a ballpark figure. I always calculate manually when I wish to know. My panel shows 42.5 to 43.5 but actually its about 39 or so... which is not bad at all. Loving it...

Average mpg reader by fithopeful

I hope that I am not repeating an old post (I didn't find anything on this after a brief search). I have a 2009 Honda Fit Sport (automatic). The average mpg read-out on it this last cycle read around 43mpg but when I calculated it myself based on the miles driven and the gas used it seemed closer to 38mpg. Has anyone else experienced anything like this? Perhaps there is something I am not taking into consideration when I do my own calculations but I had my husband check it as well and he got the same thing.
 
Thanks!

I'm glad to see I'm not the only 09 fit owner with a warm and fuzzy fuel economy meter. I'm sitting at around 850 miles right now, and am averaging 33.4 (mix) according to good ol' math (manual tran). The meter is telling me 38.4. It should be noted that I coast whenever I can and don't drive like a teenager anymore (so far, I've found the best feature of this car to be the fluctuating bar that let's you know your fuel economy based on the 0-to-80 scale--it's really turned me into a less aggressive driver.
 
I guess we'll have to see if this reconciles itself in 650 miles when I hit the magic 1,500 mark. It's funny, if the meter didn't exist, I'd be happy pulling 33 in mixed conditions... Now I just feel like I'm getting jipped.

07 Sport Auto update by bobw3

My last MPG with my 07 Sport Auto was 37mpg for about 75% highway and 25% suburb, including about 1/4 of those miles driven by my wife who like to zip around more then me! The only change I've done is kept the speed right at 60mph instead of 65-70mph for my 20min morning commute.
 
The speed limit is 65mph, so by staying at 60mph, I just stay pretty much in the right lane and listen to the morning news. It's more of a relaxed drive than going faster. Plus I can mostly use the cruise control pretty much the whole way to work, so the MPG improvement is not only because of the lower speed, but also because of the constant speed, vs speeding up and slowing down by passing folks all the time.
 
It takes me a few more minutes to get to work, but my mpg went from 34 to 37. I don't do any coasting, hypermiling or any of that stuff. Just keep the speed a little lower on the highway and don't race from stoplight to stoplight.

I previously posted my experience with an optimistic mpg readout. I have a manual sport. Mine was more than 25% optimistic very early on. With my most recent fillup, the meter was only about 12% optimistic. I'm not sure if this is because the car is getting better mileage, or that the meter is "adjusting". I'm still curious to know if anyone has any ideas just what this meter is measuring. Is it engine vacuum, rather than fuel consumption and distance? Why would it get more accurate over time (the magic 1500 miles)? For my first 750 miles of mostly city driving (80% city, 20% highway), I have averaged 36.9 mpg. On the other hand, I stop the engine at stoplights, coast, shift early and do all of the hypermiling sorts of things to get the best mileage. My highway speed has been right at 65, always with cruise control. I've achieved round-trip highway mileage right at 50.0 by the meter. Actual mileage was 38 for that particular trip. I typically use cruise control and set the speed at 29 mph on 25 mph speed limit streets and take 35 mph streets whenever possible for their better mileage (set the cruise right at 37 or so).
It's just an experiment I've been doing, to see just what sort of mileage potential the little beastie has. My criterion for deciding on the Fit in the first place was the potential to get greater than 30 mpg in town running errands. With care, it certainly can meet that standard. Also, the rumor is that the mileage will get better after the first 5,000 miles.
Due to stopping and starting the engine at stoplights, I'll likely end up replacing the starter sooner than I otherwise would have. BTW, did you know that Honda wants more than $400 for a replacement starter and, are you ready for this, $700 for a replacement alternator. Wow.

Mileage - '09 sport auto by byron2

First tank on the hilly San Francisco Peninsula: avg 27.8 per the computer. One 20 mile freeway stint at 75-80 mph showed 38, but then it dropped pretty quickly for the two miles of suburban hills on either end if the freeway run.
 
Car has on ~220 miles on it now. Still a tight motor. Should slowly improve over time. Nice car!
