I got just under 34 my first tank, but only a little over 30 on my second tank. I think I drove it harder during the second tank and used the paddle shifters a lot more than I did the first tank. A lot of highway, but at speeds from 70 - 90 so that didn't help either.

 

I am so disappointed... This weekend, I did 144.3 miles, at least 80% highway, and filled up with 5.078 gallons, for about 28.4 mpg. I did about 65-70 mph using cruise control. Why is my mileage so low???

 

filled up and calculated 35 mpg!!! keeps going up as the miles add up!!

 

I drove from Minneapolis to Fargo to pick up my Fit and on the drive home on a very windy day going 75 the whole time I got 40 mpg.

quite happy with my first drive with it.

 

My best has been 36 mpg on the freeway, 28 mpg around town. The 28 was a recent number and my best to date. Maybe there's some hope for this thing! I'll have to take a little road trip now and see how it does on the freeway.

 

Last fillup for around town (with AC) showed 28, an all time high. My best so far has been 36 on the freeway. I don't have any idea how people get into the 40's with these things. ~4000 miles on Sport Auto.

 

My all time high has been 28, and that was HIGHWAY! I usually get 25 mpg for my all-city commute (34 traffic lights in 10 miles)

 

Last Tank:

297 miles @9.46 gallons = 31.4 miles per gallon

Car has over 5,500 miles.......and one oil change

90% FWY(Carpool lane avg. 75-80mph) and 10% CITY

 

xorbe, what about that mileage? Did your results stay up there, or was this just a one tank variance due to putting in less than the previous fill?

I think that the long tank fill tube makes it very difficult to get consistant fills. From the sounds of everyone's reports (and my experience) I think that the gas used in a fillup is +/- 1/2 a gallon.

My first mileage post. April 20 was an overfill, April 30 spent most of that overfill. My drive is about 80/20 fwy/city. CC @ 65-67 whenever possible. I drive until the low fuel light comes on.

As stated in another post, I believe that the long fill tube towards the under the driver seat fuel tank makes consistant fills difficult. I believe that most fill-ups are +/- 1/2 gallon.

That's an excellent point, and it may account for some of the wide variance. On our small 10G tank a small difference in refill can make a huge difference in mpg. So I guess the best thing is to calculate mpg over the last ten tanks, by adding all the miles and dividing by all the gallons. I think the heart of the discrepancy is that with a small HP engine, tiny differences in driving style make a bigger difference in mpg than with a large engine. Hey even A/C is a huge change in engine power in our small cars and it's not that noticeable with larger engines. I also notice if the vtec results in bigger differences than most cars in mpg, since it's almost a different engine with two valves wide.

 

I am now about 3k into my Fit and mpg is consistantly 33-34 during mixed driving in SoCal with the AC always on. I have yet to take a long distance road trip so I really have not used the cruise control. I hope to this next weekend so I can see if I can hit the 40 mpg range. I am happy with results so far though and besides it really is a fun car to drive.

 

I'm almost to 9k miles now. Getting right around 35 mpg with lots of highway driving. When city driving (city as in downtown Columbus, OH) is added in it usually drops to 32-33. I have seen 40 mpg before on long trips that are totally freeway.

 

Just got my auto Fit Sport last week. I'm commuting 60 miles a day plus going out on sales calls, so the miles pile up fast. The commute is very mixed, from bumper to bumper traffic to open interstate to bucolic country roads to downtown. The Fit's the best car I've ever had. VERY nimble, quiet (to me), plenty of power off the line, and I've gotten 34 mpg on my first fill up. I'm not above zipping around a bit, but I also look ahead and try to coast down rather than do a lot of braking. I'm ecstatic with my new car! I hope to improve my mileage as time goes on.

 

I was getting 27-29 MPG city driving, I tried to stop being a lead foot and got 33 mpg city. Havent tried all highway.

 

Maybe its the ethanol,10%-15%. In my state its 10%, and I believe thats hurts the mileage. Ive slowed down to 60-65, coasting when ever possible. No tail gaiting. Trying to limit break use.
I got scanguage II and it helps, its shows the mpg.
I got 34mpg last tank.
I was getting 28-31 before.

 

That's a big jump in mileage, Coldstorage, over 13% by my reckoning. Congrats. After reading about the hypermilers (mpg extremists who rely on technique as much as equipment) I realized how much difference driving habits could make. My car seems to coast forever. Sometimes I let off the gas 1/2 mile before I need to stop, traffic permitting. I have the advantage of driving a long rout over and over, allowing me to dial in each turn and grade. I try to be doing 30 mph or less when I do have to apply brakes. I don't often use high throttle acceleration; fortunately the Fit's part throttle performance off the line is very satisfying, and I typically leave other cars in the dust. I think this is due to the long stroke configuration of the engine, V-tec technology that preserves low end torque, and an exceptionally responsive auto trans.

Another aspect of efficiency is the ability to take corners safely at high speed. The car points very well, with precise steering. When you do approach the limits, the understeer is gradual and forgiving. It's lots of fun, too. I'm shaving minutes off sections of my commute and getting better gas mileage at the same time.

I got 36 mpg on my second fillup. I'm aiming for 40+.

I'm eager to hear about your tips and tricks, or anyone else's for that matter. If we pool our knowledge we'll all benefit.

About the automatic transmission: I read in an unsubstantiated report that the Fit's transmission was capable of locking out (getting a direct mechanical connection) in every gear, not just top gear like other cars. Does anyone have any information on this?

Rock on,

I drive a FiT Sport Automatic and nearing 2800 miles on my car. I drive very conservatively, never accelerate hard, keeping the RPM under 3k, and always driving on the freeway between 65-68. I drive about 60% Highway 40% City:

1. 307 Miles, $29.35, 9.062 Gallons, 33.88 MPG
2. 605 Miles, $29.61, 9.492 Gallons, 31.39 MPG
3. 926 Miles, $28.46, 9.126 Gallons, 35.17 MPG
4. 1240 Miles, $29.56, 9.298 Gallons, 33.77 MPG
5. 1561 Miles, $32.69, 9.733 Gallons, 32.98 MPG
6. 1868 Miles, $34.59, 10.000 Gallons, 30.70 MPG (Wife drove it :P)
7. 2202 Miles, $32.32, 9.651 Gallons, 34.61 MPG
8. 2556 Miles, $32.27, 9.881 Gallons, 35.83 MPG

I always drive until the fuel light comes on and fill it up as much as possible. Hope this helps .

 

Hey,
Ive been trying to get the perfect highway speed. I want to use cruise control. So I wonder if 65 will be as efficient as 60. 60 seems to slow, I dont want to be annoyiing to others. I would like to stay in the center lane.

Any way, Ive slowed down for the first extended time in my life. I always would go 75- 80, be the fastest or next fastest.

I think when I can, I will go 65, But what would be the most fuel effiecient speed???

 

Mrmarried, we drive similar routes. At the moment we have similar mpg (mine doesn't mean much since it's based on only two fillups). However, I have a different point of view about acceleration based on years of driving my Suzuki Sidekick (26-30 mpg in the summer). I found that keeping my revs real low didn't improve mileage. The Suzuki's engine just isn't very efficient at making power below 2500 rpm. It is much more efficient at making torque between 3000 and 3500 rpm, and this is reflected in improved gas mileage. It's very similar to the difference between riding a bicycle in top gear all the time versus riding in a gear that you can keep a comfortable and efficient cadence with. With the Sidekick this axiom holds true when acceleration is needed, while in steady state driving the usual approach of lowering rpms is true. That car has a 5.33 rear end, it really screams on the interstate, but for a 4x4, truck framed breadbox it gets amazing mileage due to its small 1.6 liter engine.

My Fit likes to jump away from a standstill even with part throttle application, revving up to 3000-4000 rpm. You can feel the variable valve timing kicking in and giving an extra burst of torque. In fact it feels more responsive off the line at part throttle than it does at full throttle. I'm going to try feathering the throttle from part the full to see if I can get the best of both worlds. No, it won't be very fuel efficient, but I don't plan to do it very often.

A caveate of extreme light footedness relates to the pumping losses involved. If the throttle is never opened very far, the engine has to pull all the air it needs around the nearly closed throttle butterfly valve, sort of like trying to sprint while breathing through a straw. That's one of the great advantages with diesel engines: No throttle valve. The engine gets all the air it can all the time. At any rate this is why some mileage authorities recommend more open throttle settings when accelerating; you might want to experiment with a tank or two.

Coldstorage, I don't know where I saw it, but I recall seeing a mileage vs. speed graph for the Fit somewhere. Maximum efficiency was at about 55 mph, with very little difference between 50 and 60. As you might expect, the slope of the graph on the lower speed side was gentler than on the higher speed side. If memory serves, the graph was getting very steep once you passed 75 mph. This graph has made me reconsider my habits. It makes more sense to go slower on the interstate (70 vs. 75) and faster on secondary roads (63 vs. 58) thus maintaining about same overall speed on my commute but doing so more efficiently.

Hope this helps.

Cheers
