Any more info for long distance hwy trips over 70 mph? Don't have a Fit yet, but hoping it will be much better than my Integra on the highway (EPA 28). Just took a 1,200 mile trip averaging about 72-3 mph with a few short city miles. Overall average for the trip was 37.0 mpg. I do run 40 psi and synthetic oil which help some.
I am hoping a Fit can get near mid 40's under similar circumstances. I know the Fit will kill my city mileage as people seem to be getting mid 30's, and I am in the mid 20's.
I was able to get with constant highway driving (going back and forth to Chicago from Nashville for work) 35+ MPG out of a Gen III (1992) Toyota Camry Wagon automatic with a 2.2l in it and over 200k miles on the car when I ran Shell or Chevron super. Better than the EPA estimate for the car. No detonation either with super as seen with plus (I never ran regular in any car prior to the Fit).
On the Geo/Suzuki, I would get 4-5MPG better out of super than regular. With an 8 gallong tank, that would equal 32-40 miles more out of a tank.

I have no freakin' idea how you people are getting 40+ mpg. I drove absolutely feather footed, all highway 55-70 never more than 3K rpm at any time, almost zero in-town, no A/C windows up, washed and waxed, used cruise control a lot, and only managed to match 37.0 mpg (the highway rating of the sport a/t vehicle). 40psi in the front tires and 38 in the rear too, which I don't like to do normally. My first 2 tanks were 32.3 and 29.2 mpg, pretty heavy-footed I was.

Know anything about driving hybrids ('hypermiling')? You must drive like that. That means never 65 mph on freeway, neutral downhill (freeway or city), and on city, you must use brakes as least as possible (if you use too many brakes, therefore also toomuch gas)
3000 RPM may be high. on city, it's possible to keep under 2500. I've tried it w/ my bros CRX and my own Fit. I only go 3000 when goign uphill.
btw i'm not a hybrid driver,but i looked into them (and their driving technqiue) as i was interested. I chose fit cuz i realized the civic h is too big and mileage wasn't as good as i'd hoped.
Also, do you drive a lot of city? city driving hurts autos more, b/c the engine is still moving a good amt when you're stopped at a stop sign or light. You can try to set it neutral on every stop light.
dang! my first tank only got 24 MPG!!!!! WTF???!! it's mostly city driving, and lots of idling, but no A/C....and the tires were underflated... I have no idea what the dealer throw in there, prob some cheap watered gas...I'm disappointed... and when I open the gas tank cap, there's no pressure hiss'n sound... hopefully next tank will do better... NOT GOOD!!
The dealer probably did not fill the tank all the way. Remember that you are getting 0 mpg when idleing, and city driving uses a lot more gas. Lots of short trips also hurts mpg as the engine is never warm.
Will premium lower the mileage, since it is more difficult to combust?
Edit: I did my mileage run on regular. The previous tank was premium accidentally... the ol' VR6 Jetta requires it, tough habit to break, punching the premium button... (Yes, I know just to stick to regular.)
No, don't put premium unless it is needed. You will be throwing your money down the drain with NO ADDED BENEFIT. Car WILL NOT run smoother, cleaner, or faster. Octane is the rating to resist detonation. Higher the octane, the better the ability to prevent premature ignition of your air fuel mixture. So when you piston is moving up (and not all the way up), the air fuel will ignite on its own (not by the spark plug). Because combustion occurs, the piston will want to move down (but its already moving up to finish the compression stroke). It causes a rattling in the cylinder called PING which can cause serious JUJU to the engine. And so you're like well, higher the octane, the better to resist detonation. That is very correct, but the engine in the FIT will never detonate using this lowest grade fuel. So... there you have it, lowest grade is only needed.
I wonder what the halfway point and Empty point on the gauge is in terms of gallons? I've driven a couple cars that hid a gallon or two below the E, so you wouldn't ever actually run out of gas.
If you drive light-footed and get 37 mpg (US), then I can say that the half-way mark
is reached at 180 miles, and the light comes on at 336 miles (156 miles on the last half of the gauge). Well that's what I saw. According to the owner's manual, there is 1.7 gallons left after the fuel light comes on.
Therefore, at 37 mpg...
4.86 gallons on the first half of the gauge (180 miles)
4.21 gallons on the second half of the gauge (156 miles)
1.7 gallons after low-fuel light activation (62 miles)
Has Any One Met Or Broken The 40 Mpg Us Gallons
. oh well, i'll try next week to behave
