I bought a manual sport with navi in April, and I've been calculating the MPG every tank by hand. The range that I am getting is 30-35. The worst I had was 29.5, and once I think I got close to 36.

The electronic MPG indicator consistently overstates my gas mileage. Once I think it was only 1 MPG over, but usually it is 4-5 over (for my most recent tank it stated 38, but I calculated 33).

I've had tanks that were almost entirely highways, and ones that were mostly city driving (although no stop-and-go; I'm not in a big city). I do occasionally have hills that I drive, but not too bad. Driving on the NYS Thruway at 75-80 mph gave me about the same mileage as city driving; mileage has definitely been best when I am on rural highways doing around 60. I've had A/C on and A/C off. I generally am playing music somewhat loud (don't know if that matters). I am a little aggressive in my driving, but not too much.

Anyhow, I hope this information will be helpful!

Incidentally, I LOVE the car.

 

Yeah the MPG meter is known to be a bit optimistic. It doesn't matter how loud you play your stereo, it won't effect fuel economy.. Glad your enjoying your Fit!

 

If you think playing music loud affects mileage I question if you should be driving at all. Seriously, yes you can increase mileage by 3 mpg with radio off.

 

We get between 35 and 40 mpg. To get 40, the mpg indicator needs to read at least 46. Biggest factor for us is headwind.
Our driving is mostly highway with cruise control on.
We always keep the volume low for added mileage.

No way. Your not getting 3 mpg by turning off your radio. The amount of energy consumed by your radio is so minuscule that it makes no measurable difference in fuel economy. The highest I would believe is mayyyybe 1/4 mile to the gallon saved not using the stereo and other accessories, but again - it's negligible.

 

Have you ever checked your mileage with and without radio on? If not try it and report back. At least 3 mpg difference.

 

Do you have any idea the amount of variables that exist between fill ups? I'm quite sure you performed this test with the outcome already assumed in your mind. I'm willing to bet that you were:

• Looking to improve fuel economy
• Turned the radio off, expecting this to improve fuel economy

Over the course of that tank of gas, you likely drove the car just a little bit lighter than usual (even if it was a bit subconscious) but you attained better fuel economy not by having your stereo turned off.

• Differing road conditions
• Weather/wind
• Cruising speed
• Lighter foot
• Lighter traffic/less stop and go

On and on.....these are the conditions that effected your fuel economy during your test. The amount of fuel you saved by turning off your stereo is not going to be 3mpg, it will be so low that it is very hard to measure.

 

i added a 1000w amp and i seen no diff.
still same MPG.

 

Reako--
I drove through your town about 1 a.m. Sunday morning. Getting sleepy so I turned up the volume to keep me awake. Mileage went way down. Had to buy gas in Hannibal.

Just kidding. Somehow driving past Troy MO makes me sleepy. Or maybe because it's always past midnight.

Cheers

 

Reako,

I don't know Black3sr but I'd bet one of my three testicles that he is "pulling your leg"

 

Well technically, any electronic accessories will lessen your mileage, but unless you are running them all at the same time, I don't see how you could measure the difference.
You could always do A-B-B-A testing to find out if you have a scangauge.

 

Using your radio AT ALL will lower your mileage at least 5mpg, maybe even 6. What you really need to do to raise your MPG is to:

1. no radio. Not even humming. The increased sound waves produce shock waves that make more wind resistance.

2. hunch over when driving, close to the steering wheel. This will help tremendously on drag. You will gain at least 4 mpg. Older people know this from way back.

3. When starting out at stop lights, open your door and push with your foot while in neutral to get you moving, then put it in gear. This will add another 1 mpg, but if you do it consistently, give yourself 2 + mpg.

Make sure all your passengers do this too!

 

No sheet eh. I believe the original question came from a blonde.

 

Yeah, additionally you should get white or a light color Fit because the weight of the extra sunlight absorbed by the black or dark colors lowers your fuel economy 2-3mpg.

 

Is yours an '09? If so, I'm wondering why your mileage is better than mine is. It has not ended up being quite as good as I was expecting...

 

Every Fit owner knows the real-time MPG readout is optimistic by 4 to 5 mpg. Kind of sucks not to be able to rely on it, unless you want to subtract 5 from the number every time you look at it.

Mileage is affected by the following:

tire inflation level
aggressive driving
stop and go traffic
A/C use
unnecessary weight
properly maintained car
aerodynamic drag (driving with windows down, roof rails, spoilers, etc.)
driving speed on the highway (big difference in mpg between 60 mph and 80 mph)

Radio usage does NOT affect mpg by any measurable amount. Whoever said that is yanking your chain!

 

 

Ours is a 2009. We have about 10,000 miles on it now, with 5,000 put on in the last five weeks.

Just filled up coming back from Quincy. 298 miles/7.7 gallons=38.7mpg. Indicator said 42mpg.

The entire tank was highway driving (St. Louis to home, home to Quincy, and back), cruise control on, no more than 65 mph. I take it easy in city traffic, too. I would say this is an average fuel economy for us. I don't do anything special.

Cheers

 

Exceedingly high amounts of diesel fumes and cow farts.
