My last tankof gas, as filled up yesterday:
342 miles/ 8.2 gallons= 41.2 mpg My best yet.

We usually get 32-33mpg, but I started implimenting some basic hypermiling techniques.

 

Could you please describe your techniques?
Thanks!

 

For all of my 13 years of driving I have always just jumped in the car ,(whatever car I was driving at the time) floored it, and didn't think twice about mpg. Having owned several "performance" oriented vehicles that averaged around 15 mpg the 32mpg that the fit got was great. However, with gas prices near $4.00/gallon I felt it was time to start being conscience about my driving style and fuel consumption. I began looking here on fitfreak.net in this subforum. I saw a word I had never seen or heard of before: hypermiling. Having no clue what it was or if it even really existed I googled the term which resulted in a few hundred thousand responces and one main website: cleanmpg.com. A few hours later I had read everything there is to know about this driving technique. Now it seems some people go a little overboard and move into the relm of "unsafe" driving statigies all in the name of Hypermiling. That is not for me (If I'm going out in a car it certainly isn't going to be going under the speedlimit with my car shut off). So I stuck to the more basic of hypermiling techniques: Slowing down to just under the speed limit; using cruise control, putting the car in neutral at stop lights and on hills, driving with limited braking, and a few others. In the fill up I saw a 30% increase in FE. We'll see how I do this next fill up. So far it's shaping up nicely

 

I had my second fillup last night. 11.4gal (I could see the gas in the filler tube). Light came on at 343 and I filled it at 355mi. Thats 31.2MPG Mostly in town/back roads and short 3 - 5 mile hiway trips.
I was a little careful with the driving, but nothing over-the-top. I know I could do much better but I'm really happy with this for an AT. This tank I think I will drive like a nut and see what "the worst MPG" is for the car.

Based on what I learned riding my Motorcycle (KLX250), The AT should be able to get well into the 40's under the right conditions. My motorcycle averaged about 55-60 MPG driving "normally" and driving between 40-50MPH on back roads shifting really early with only occational stop signs I got 82MPG. The same should apply to the fit although not to that extent obviously.

 

Thank you!

 

Havea, you really shouldn't overfill your Fit. Pump gas until the pump stops. Doing it any other way will lead to inconsistencies, and your data will not be accurate. Plus it's also risky to your evap system.

 

inconsistent? No more so than the fact that each pump clicks off a little different.

Risky? I've heard that before but, so far the only real evidence I've seen is that if you get hit while your filler tube is full, it could shoot the gas cap off and some gas with it. Might not be good to have fuel everywhere during an accident. Otherwise, I've done that with the last 4 car's I've owned and never had an issue. What is it supposed to do to the evap system? Do you have a source I can read about it? Most of the time they say its cause you spill gas which is a waste, or that it pollutes the atmosphere. I dont really care about that. I dont feel its that big of an issue. There are larger problems out there.

 

My concern was just the opposite. You shouldn't drive it all the way down to the bottom of the tank like that. But, since the car is new, it's not a problem. When the car gets older and there's more sediment built up at the bottom, that's when having the fuel pump suck up all the gunk may cause injector problems and clog up the filter.

Besides, I noticed that once you go past 1/4 tank, the needle moves a lot faster towards the E than normal, so it is really difficult to guesstimate how much farther you can go.

 

Just got back from a road trip

37mpg 40 miles on turn pike, 353 miles on 2 lane back roads.
Refueled at 393miles(light wasnt on yet)

On the return trip we took the highway back. Cruise control set for 70mph. That yeilded 35MPG.

My G/F loves cows and wanted me to mention that we saw some.

I think thats good for an AT. One more thing to note: Even if you use S mode to keep the AT from downshifting on the highway with cruise control, you still have the torque converter that locks and unlocks changing engine RPM. I found that at 70mph, it had enough torque to keep the converter locked up (lower RPM) where at 65, it would unlock up hills much more often. Just an FYI.

 

Oh yeah, I forgot to mention that I also did a half tank of flooring it everywhere through all the gears. . .using S mode. I also did a number of drag races with my friend's Hyndaui Accent. I wanted to see what the worst was likely to be for the fit. 26MPG.

*gas station attendant filled the tank, differently than I do

 

I have no idea how anyone is getting above 35 mpg out of one of these, pass on your secrets please! If I am driving sporty I am getting 26-29 mpg. If I drive trying to get good milage I am getting 31+ around town, 33+ highway.

When it clicks during refueling can leave way too much empty room for gas. When I refuel, after it clicks, I shake the car side to side and keep clicking it. Then I can get in up to 2 gallons more (11+ gallons). Evap system be dammed! Never had any issues doing this -- yet... I can go over 100 miles before the needle even moves. 230 + on a half tank according to the gas guage. If I stop when it clicks then 60miles before the needle moves and about 170 on a half tank.

 

I don't know what to tell you...

My daughter drives her AT Fit all around without too much care for fuel efficiency and she gets 31-32 around town and 38+ on the highways. Her Fit is a 2007 with 28k miles on it and we live in southern california...is there an additive in your fuel in CT that reduces emissions at the expense of fuel efficiency?

I've read on this and other auto sites many times where folks are reporting poorer fuel mileage in some parts of the country that they think is due to fuel additives. When you say 31+ on highway mileage, how was that measured? Did you go on a long drive on the interstate at a steady speed and then refill the tank?

 

She weighs 50 lbs, the rest of us weigh 400 lbs.

 

May be my bad on my mileage. We do have 10% ethonal here on the east coast. That drops our figures at least 3-4%. I believe it is supposed to have only 70% of the BTU's (heat energy) of gasoline. Perhaps 3 mpg less. Beyond that I don't see how some are getting "super" mileage? I am jealous... Not complaining about it, still damn good. Especially around town.

Anyone know if using a synthetic oil helps any? I have searched here and not really seen anything about it.

 

Thought I would chime in and give you guys something to shoot for.

I drove my wifes CRV 2008 EX (automatic) home from the gas station and achieved the below( 42.7mpg on a 4.1 mile trip):



Mind you I never exceeded 45 mph and encountered 6 stop lights and had to encounter several hills. I did not use A/C and had the wife and son in the car. I coasted a lot in neutral going as far down as 10mph below the speed limit.

Also, on her last tank she averaged 27.1 mpg which is about 85% city driving, she is starting to learn the way of the hypermiler.
(this thing is rated 21mpg city and 27mpg highway)

Oh, and you might be glad to know that my great mpg and the price of gas has conviced my brother-in-law to purchase an Auto sport FIT, today actually.

 

2700 Miles on the car and I FINALLY exceeded the 30mpg mark. Gas light went on at 290miles and I filled up 9.26gallons for a total of 31.31MPG city. I am so stoked. My last fillup was 27 and best was 29mpg.

What I did differently this time was concentrate on my acceleration from a stop light. I made sure it was a nice and steady, easy acceleration instead of the rush to 3K rpms and then the hard shift into second. I was also driving an average of 60-65mph on the freeway in the slow lane. Driving up hills I was doing a steady 40mph instead of trying to go faster.

 

Are you coasting? I would coast in gear and in neutral. You should be able to get over 31 but your terrain and city traffic may be a problem. Also, try not to reach a rpm of 3k, stay around 2.5K if you can.

 

Using the scangauge last night, it's better I think to keep the transmission in total lock-up. Better to (sport a/t) put into 4th locked, than to let the motor strain in 5th in slushbox mode (no lock up).

Same principle for small hills, the a/t will leave lock-up mode, so pop it out of cruise control and bleed the speed until the crest.

Coasting down the Altimont in N for 3 minutes at 70 mph @ 270 mpg was fun...

 

Can you explain what makes the transmission lock/unlock and why that would be good or bad?

Also, if you left it in D, the fuel should have cut off, giving you (effectively) infinite mpg.... Or so I've heard; I won't know for sure until I get a scangauge, which I keep putting off on account of the wife.
