Has anyone gotten the rated 38 mpg? I'm on my 4th or 5th tank full now and the best I've seen is 30 mpg. One tank was all hwy. No matter how I drive it's the same; city/hwy, spirited/conservative. My guess is it's because of the A/C. Thats the only constant so far, and I figure an A/C has got to tax a 1500cc engine pretty heavy.

 

I'd say so.
I drove from Falmouth, MA to a little south of New Haven, MA and back a few weeks ago (buying wheels) . I sat in traffic for about 15 miutes in Providence, RI, and idled in the parking lot where I was meeting the seller for about 5 minutes. I floored it on every onramp, and drove about 70-75. I got 327 miles on 8.6gallons. Thats 37.8mpg, with 2 people in the car, and 4 wheels/tires in the back for half the trip. The AC will kill the mileage.

 

I would say you should start seeing stable fuel mileage like that after 800~ miles or so, and also with more highway driving that city.

How many miles are on your Fit? When I got my s2000 a couple years ago, it took a few tanks before I saw the rated fuel mileage. Haven't seen it since 'cause I can't keep my foot off of the accelerator.

Was all this with your A/C on or off?

 

I got 37mpg on my 1st tank of fuel in the fit.

 

we get a max of about 330 we have 2k miles. I dunno, I think in the winter we will see more miles to tank

 

from what I'm seeing I think aallbbeerrtttt might be onto something. Gas quality in some areas might be suspect. I just got done with my "dealer tank" and posted 32mpg and I was pushing my Fit pretty hard at times. At 2000 miles you should start to get a bit more consistant results. You "might" try stepping up to the next grade of fuel, premium, or super, and see if higher octane helps you at all. Try another brand if you are a hardcore AMOCO guy or something like that try Shell or Chevron. Good luck

 

hi guys.


i have like 5000+ miles on my FIT and i consistently get about 33-34 miles combined.

i do mostly do highway driving at like 80mph (the rev at that speed is 4000rpm).
i would imagine if you drove consistantly at like 40mph until empty, then you'd get closer to the advertised mpg rating at 38mph.

i also tried supreme/ premium gas and i noticed it doesnt make any difference.

w/ or w/o A/C?

 

Best I've ever gotten has been 31 MPG. Tried 91 at first then realized the owners manual says to use regular, so I tried that thinking it might get better mileage. Neither made a difference. This was 60% hwy, 40% street and no A/C.

Needless to say I am pretty disappointed since most people say Hondas have been known for getting better than sticker.

 

Dont fill up with premium unless you got a motor swap that requires it = high compression. Manual says use regular then use regular. Premium gas doesn't give you more power if your motor doesn't compress it to the point to make used of its anti-knock abilities.

 

I've put about a 1k miles on my Fit now, and after some use of the A/C, I have determined that it cuts down my fuel economy by only 1-2 mpg.

As long as I stay with normal driving habits I am still maintaining 36-38mpg.

We'll see how that is affected here soon with the install of the intake and exhaust.

 

I have officially taken my first long trip with it and was able to easily monitor the MPG's.

With A/C on the entire time, I got 30.4 miles to the gallon.

I am not complaining.

Just to emphasize: regular or supreme gas will not do SQUAT for the Fit. 91, 89, and 87 octane gas have about 18k BTU/lb of energy. There is no difference in energy in different octane grades.

91 octane WILL burn more slowly and conrollably at higher temperatures and pressure than 87. 91 octane gas is marketed towards high performance engines which were designed to utilize the burn characteristics of 91 octane fuel.

 

Ive gotten a low of 28mpg (all city traffic w/AC) to a high of 38 mpg (all hwy w/AC).

 

Im only getting 27mpg at the most on my fit auto! wtf and I drive pretty conservatively..i don't even go over 4k rpm like 90% of the time. Maybe cuz' I always have the A/C on. But still....I have 3,200+ miles on the car and Im going to drain the oil and put synthetic on it and see how it is after.

 

I've been hearing about the dealerships falsifing the MPG on the stickers. Idk how tru that is, just a thought. Also different states/cities get different grades of gas, some more refined/efficent than others.

just my .02

Mostly true, but higher octane gas can still be somewhat beneficial. Most modern ECUs try to keep the engine at the point of detonation without actually detonating. Running as much timing advance as possible without knock results in the most power. If the ECU detects knock, it will pull timing. An engine is most likely to knock under high load or on hot days (or both). Higher octane gas can prevent knock in those situations and prevent the engine from pulling timing. This means the engine will contine to make as much power as possible when it may not have with lower octane gas.

Basically, you won't get better performance from running higher octane gas than required, but you might remain closer to optimal performance in bad conditions.

I find it hard to believe a dealer would risk getting in trouble by the FEDS by messing around with a EPA sticker! Thats crazy.

That is true about metro areas, we get a crappier blend of gas that burns cleaner but usually nets slightly worse MPG in the summer months at least. My best MPG came from a station that was ~100mi away from Atlanta.

thats sucks for the people getting 28-30 MPG,

in my 97 integra i was getting 28-30 MPG, once i installed the b16 tranny it went down to 26-28, and a lot faster than these fits.
