I have a new figure. Mixed driving for 231 miles with a mpg of 34.8. I am keeping the rpms at or below 3000. I shift alot. Also some of the trips have been very short. On the short trips I warm the car up before driving.

first tank 36.5 mpg 40/60 city/hwy second tank 34.5 mpg 60/40 cty/hwy thrd tank 40/60 cty/hwy 37.83mpg. lovin it driving spirited not trying for best mpg. next tank I will take iit easy if I can try to squeeze everything I can out of this $3.40 a gallon gas.
with my 5spd sport, i only got 26mpg on my first tank, about 75% city driving.
at my second tank and inflating the tires to what they were supposed to be, i got 30mpg with about 65% city driving, the rest highway usually going 80.
i was extremely disappointed with my first tank- i felt gypped (though my tires were under-inflated)! and i am a bit frustrated with the second tank as well... but i know it will improve over time.

Keep in mind fuel efficiency starts dropping around 65-70mph really fast because of drag and higher RPMs. So between doing 2/3 city and 1/3 highway around 80, 30mpg is pretty good!
I am averaging (ad gonna toss out the one fill cause the tank was WAY over filled..knew it was a little but I think it majorly skewed the resuls cause it came to like 70 mpg.. ) unless someone knows how much is in or fits the pipe leading out of the tank. anyway.. I'm not quite at 1/4 tank yet.. will fill it later.. and at 128 mph.. but i've been averaging into the 40ish mph range other than the first 2 days or so. the I was down to 35 but also not use to the gearing etc..
I primarily have hills (moutains) twist turns, freeway speeds, 55 to 25 then up to 45 back to 35 type driving..

Does anyone know the optimium speed for fuel efficiency for auto? I would think it is actually lower than 65. I recall we moved the speed limit to 55 back then to save fuel. So I would think "most cars" is around 55 to 60 range.
Base, 5 speed, stock tires, A/C on occasionaly.......
33.5 first tank (mostly city, what was in the car when I bought it, so test drives, dealer putzing around, etc)
38.9 second partial fill (all highway)
Both were miles driven/fill up and not doing an "over fill" stunt.
Everyone burning 87 octane? I generally don't, but the owner's manual claims the car can use it, so I am trying it for now.
I ran super in my Toyotas and Suzuki Swift, plus in my Volvos and Mercedes in the past, the increased mileage made worth the extra costs of $0.10-$0.20a gallon.

both our first tankfuls were well over 40 mpg. Never over 55mph, little traffic, no Ac, no Idling, second tank was 50% city driving with very lite foot.
first tank 45.7 second tank 45.2, 44 PSI all tires, never over 55 mph, lightfoot driving - mixed city and highway. No AC, no idling. Base MT 800 miles total now.
Remmember that tire over inflation can cause overheating, bad tire wear and blowouts. Got to stay close to recommendations.

I dont know everything about fuel so teach me on this if you can. What I have read about gasoline in the united states is that besides having additives the main difference between regular unleaded and super unleaded is the flamable range limits. Some cars require different flamable ranges because of design or tuning. One symptom for some automobles is running poorly or preignition. I did not know you could get better mpg by upgrading from regular to super unleaded. Also does the cost make it wort it? Besides owning a fit I own a rotery powered second generation rx-7 which I always burn regular. I save money by doing this and it runs great. I have even been able to acheave an impresive 25mpg on the freeway. To put it in honda Fit terms it would be like getting the news that you got 45 mpg in us gallons. thanks for your time and i look forward to reading the replies.
I had an 82 Subaru that would get better hwy mpg with higher octane fuel. If I was driving a longer distance I would put in some higher octane gas. I would get 3 to 4 mpg better on the highway. The real help wasn't a reduced cost to drive but I could drive farther between fillups. It didn't make enough difference when driving shorter trips to make it worthwhile. The high compression of the Fit motor might see some benefit from higher octane even if it isn't needed. When I get mine I will try higher octane and see for myself.
i'm buring regular 87 octane in the fit. my accord needs higher octane but that is primarily cause when the car was made regular was running higher octane..
Big Fit basicly if you have a older car the higher octane might benefit you.. otherwise no.. on the rotaries I don't know.. the one time I looked at them the sales guy was doing the it will burn and run on anything.. kerosene, white gas etc.. in a pinch.. (course probably just about anything will run on it in a pinch Ok maybe not a diesel engine.. but.. ) I'd just do a comparision.. run a tank of high octane then a tank of lower octane then a mixture.. see if anything changes greatly.. Sometimes it makes a difference, sometimes it doesn't, my older honda will climb one of the hills out here in 3rd on regular.. but it likes to knock doing it.. the fit on the other hand runs the same hill in fourth or fifth.. depends on if I had to slow down due to traffic part way up.. without knocking.
Sport 5MT. Got the vehicle with 3.4 miles on it. Drove straight to a gas station and filled it up to the brim. Drove 208 Miles mixed 40% city following a break-in regimen, filled it to the brim again with a little over 6 gallons.
34.6 mpg
I'll drive this tank down as far as I can stand it and fill it conventionally to the cut off.
When not on freeway I tried to keep RPM < 2500. I first drove like a granny, but later near the last half tank, i drove a lil more aggressive. I hope it gets better than 34. I drive highway often, but when i do drive local, i drive a lot of it, so iono how to give percentiles.
