Ive had 2 oil changes since i bought the Fit. My Oil meter was actually at 50% but the mileage was over the dealers req mileage on the last oil change.
So I split the deference just in case the meter was off.

fyi the dealership is putting my Oil changes at 5k. My meter is taking me to 7k+..

 

Food for thought. My gas mileage on my 2007 AT Fit has ranged from 21 mpg while driving all city miles in the cold Michigan winter, to 38 mpg with 95% freeway miles during 70 to 80 degree summer California weather. The Fit is extremely sensitive to stop and go traffic, as well as cold weather. Even with 100% highway miles from Ann Arbor to Pittsburgh I only got 31 mpg driving 70 mph during the dead of winter. So if you drive primarily city miles, traffic miles, or in the cold, or any combo of these things, your mileage is going to be anywhere from mid 20s to low 30s. You will only be getting high 30s to low 40s if you drive primarily when the temperature is above 32, and above 80 to 90% highway miles. At least this has been my experience. My average mileage while I lived in Michigan was high 20s for mpg, because I drove 90% city and in the cold. Now that I have moved back to California I average around 36 to 37 mpg, I drive 90% highway, and it never drops below 32 in SoCal. So there you have it, the same car getting completely difference mileage with the same driver, it's not your car, it's the setting you drive in that determines the majority of your mpg. I have also noticed that keeping your speed under 70mph improves gas mileage significantly. Driving around 75 to 80 mph I get 34-35mpg, keeping it 65 to 70 I get 37-38 mpg

 

My experiences exactly. Five-mile commute during cold (for Atlanta) weather last winter, gas mileage plummeted to 23-25 mpg, while motor minder percentages were dropping rapidly. Driving at 45-55 mph on flat secondary roads in rural Alabama in July, 40-42 mpg. 75 mph on interstates in Alabama and Georgia in July, 35-37 mpg. Needless to say, the A/C was on during summer driving in the southeast.

 

I drive 38 miles to work and average right at 40 mpg. I also do a little city driving so my tank is averageing 37.x. I am working on it and will get over 38 one day. I am on my fifth tank. This is calculated, not relying on the meter which has been optimistic anywhere from .2 to 1.5 mpg. I find the cruze control is not as good as I am, it accelerates and decelerates when it is more efficent not to do so. The car appears to get the best milage at about 50 mph. Stop and go kills it quick.

I love my FIT! The seats are comfortable, my only complaint is the ride is a little choppy, and the road noise is a bit loud, but I can live with it. I thought the workmanship to be better than any car I have ever owned. I bought it a couple of months after my wife bought hers. Mine white, hers red, if daughter gets one it will be ... blue.

 

I get 33-35 mpg because I just drive casually but lots of city/hwy mix and stop and go traffic. My BF drives it on a fill up with 38-40mpg

 

You're dealer wants your money. There is no reason for modern cars to have the oil changed at 5k mile intervals. Even 7k on a daily driven (not abused) car can be excessive. And if you use synthetic, a 10k interval is not unreasonable unless you're taking the car to redline every shift.

But hey, it's your coin. If it makes you sleep better, go for it.

 

I did a 140 mile drive early Friday morning with a 10-20MPH tailwind. When I reached my destination I was averaging 46MPG. That's with highway driving, my average speed was around 62 MPH.

After country road driving on the return (and stumbling into some cute, small Ohio towns like Orwell) I was still averaging 40MPG over about 300 miles.

The dealer gave me a call during my trip to check up on how my Fit was working, I told them the mileage was almost supernatural on this car. They agreed that it's an absolutely fantastic piece of engineering.

 

Did you figure the mileage by hand when you filled up? If you did, what was the result? This is the only accurate way to measure MPG. The OBC (on board computer) is very optimistic. Still, mid to upper 30's is not unreasonable for this car.

 

Let me shoot from the hip here:

I started topped-off, and after the 130 miles, the gas gauge was down to about 4/5ths of the gauge...

1/5*10 + 1 (gas in the tube to the tank) = 3 gallons

130/3 = 43 MPG

This is a shoot-from-the-hip and not a perfect topped-off-tank calculation.

 

To be fair, the really high (over 40MPG) and low (under 25MPG) values are probably statistical outliers, and shouldn't be factored in for reasonable mileage expectations.

 

For the new freaks, welcome. Did you find my age of owners thread yet?

Two things are in your Fit's favor regarding MPG's. First is the end of winter. Milder weather will bring improvements. The other is mileage. When I first got my 2010 last April I was sure it was going to be a 34MPG car. As I racked up the mileage and figured out how it likes to be driven I saw 38MPG averages. That's after 4K miles or so.

Right now I'm seeing 18K miles and 35MPG on the ODO. That's winter economy. The other thing I've learned is accelerator pedal position. When up-shifting I keep a light foot in it and simply wait for the rpm's to build as opposed to hitting the floor boards with the right foot. The tranny is super sweet at high revs but I'm rarely in that range, only if I havabe...

 

Calculated from fill-ups or by the mileage meter?

I did a 160-mile mountain loop in GA/NC yesterday, with some steep grades (both up and down) and a fair amount of spirited tossing about on tight, twisty roads -- in other words, with the accelerator all the way to the floor a significant amount of the time, and still averaged about 35 mpg (calculated), which I think is quite impressive for the driving conditions.

For the record, after getting the mileage meter software reflashed in late 2009, I've logged consumption in a spreadsheet for the past 11,000 miles. EPA estimates for mixed driving are essentially spot-on, and the mileage meter is pretty close.

Miles:10,949
Gallons: 364.42
Calculated MPG: 30.05
Mileage meter variance: 0.61

 

when i do alot of stop and go driving which i do daily due to homecare job i get 26-28 when i am mostly highway i get 34-35 regular driving on country roads more like30-31 but this has been only in the winter i have only owned the car 4mths drive alot but only in winter so far hoping it will be better in the summer with regular tires not snow tires

 

That was by the vehicle's meter, but my basic calculation seems to agree with the meter.

City driving I'm at a solid 28.

 

Due to the difficulties of getting a consistent fill on a Fit, I rarely get a calculated result that is within 1 mpg of what the meter shows; sometimes better, sometimes worse. I've been tracking gas mileage in a spreadsheet for about 11,000 miles, and the meter has been off by about .6 mpg+

Average 30.05 MPG over 11,000 miles is almost spot on with EPA estimates. Worst 24.5 (cold weather, city only); best 42.2 (all highway, no AC). I consider the low/high outliers to represent fill-up errors; 27-28 city and 36-38 highway is more realistic. Mileage improved around 12,000 miles, when I switched to synthetic oil, but I make no claims as to which was more significant.

 

I love my Fit for reasons other than the mpg but I definitely expected better than 25-26 mpg. When I bought it certified pre-owned it had 17's on it. Could that affect the gas milage that much?

 

200 miles so far on mine and a 34.6 combined average...

 

Hey Joescape,

I have an original 2008 Fit 5-speed, and it now has 17 K on it...over 3 yrs of driving.

I live in the high mountains of NM, but I do some city driving. I believe you can make a big diff in your mileage by running your tires at 45 psi. It makes a big diff.

Over 3 yrs of driving in all seasons......this is hand calculated......we still average 41 mpg. Slightly lower in winter, and higher in summer.

 

That's a good test bed and great mileage. I would be interested to know the tread depth and wear patter on your tires and also if you rotate them. I've always wondered if a psi increase will actually effect tire wear.

 

Hey Krimson,

Good question. This topic of tire life and higher psi has been discussed a fair bit. The general sense of those in the know is that since steel belts were invented on tires, that reasonably higher pressure does not have a bad effect on the wear of the tire. Of course, there is a limit.

i have rotated the tires once in 17 K...it was around 11 K. I am not a big believer in rotating often (some do it every 5 K). Right now our tires look almost new......seems like they will be good for another 17 K anyway, and we drive them summer and winter....no relief.
