I just bought a new'08 fit sport automatic.The first half tank got 27.5mpg, filled up with Shell reg. and got 25.2mpg driving very easy. Filled up again(Shell reg) and got 23.1mpg! The service guy says it has to break in first, about 12,000 mi. He's crazy!! New vehichles for the most part are close to 'broke in' from the factory. I read about the great gas mileage many owners on here are getting so I would sure like to hear all comments or suggestions any of you may have.I have 900 miles on it today and I like many things about the car especially the amount of room. I bought it so as to cheaply take trips around texas on wknds hiking and such but the way it's looking I might as well drive my 3/4 t P-U at 15mpg HELP!!!

 

it surely doesn't take 12k miles to break in.
but more than 900
just wait it out.
it'll get better for sure

 

my mileage didn't break 30 mpg for a while.

agreed, just give it a bit more time.

 

i've got a little over 10k and i've seen an average of 35mpg during the last 6-7 fill-ups (50/50 | city/hwy). before that i was getting between 23-27, my first tank scared me when i got 18mpg

for the last two tanks i've really been ripping through the rpm, usually shifting between 4-5k rpm. it may be a fluke, it may be the hot weather, it may be an act of God but i've increased my mpg by 2 additional miles. i'll see how this tank of gas goes before making any conclusions. my current impressions are that the L15 likes to be abused

 

Take it to the dealer, and have them link up the Honda computer under the dash. Yeah I forget what it is called. But they will for sure figure out what the problem is. I am sure it's something simple. I have an 08 Honda, before that, an 07. Both of them have good gas millage. The 07, 48 miles per gallon, at about 65 miles per hour and I noticed this right away, and the red one now with mods, easy 53 mpg at about 70 miles per hour. I noticed the time checking this at 278 miles on the O.D. Also check your air filter, check for bad O2, air pressure (in tires), start changing gears (even in an automatic) at 2.5-3K R.P.M. in the city. Don't brake hard or ride the brakes. Try not to, you know pump the gas peddle, keep a steady press on it. If you have cruse control, use it on highway, and keep the miles per hour the same, as much as possible. 65-70 M.P.H. I am very curious to know the out come, so please wright back.

 

Were you "drivin' it like you stole it?!" (Jk)

 

In my mix of city/freeway driving, I'm getting 27-28 mpg with almost 4k on the odometer. I'm sure it will improve with time.

I say give it more time and it will improve.

 

before i was averaging between 20- 25 mpg after a while i get like between 30-34 mpg... patient is a virtue they say

 

Anybody have any ideas why some people are getting such low MPG at first? My 08 Sport AT started at 31MPG and after 4800 miles is now at 36.4MPG. All of this on 100 mile daily drive in Detroit. I drive a 50/50 mix of 75 - 80 MPH highway and stop and go.

The only time I use the flappy paddle shift is when moving slow in traffic I lock it in 2nd move at a constant slow speed without having to constantly feather the throttle.
I am very sure of my numbers because I use the same 87 oct. pump at the same station for gas every fillup. I lock the pump at the first lock point (any faster and it kicks off) and stop pumping when it clicks off.

I just can't understand how one person is getting 30 - 35 and another can't get any more than 23 in the same car, from the same factory, with the same engine control software? I worked many years in the US auto industry (that's why I now own 2 Hondas) and understand manufacturing. If there is actually this large of a swing in any aspect of a product it would never get to market.

I don't want to come off like a jerk but it has to be the driver. With the level of quality that Honda required for the parts we sent to Ohio for the Accord, I just don't see any other item that could cause the large swing we are seeing in the reports at FitFreaks.

I am not here to say that any manufacturer, including Honda can't have a problem car or two, but to believe that the product has this kind of variance built in just doesn't hold water. No quality manager would let this happen.

 

each tank i get about 250 miles and i try driving easy but no matter what its still around 250...i think i'll bring it into honda soon to get that checked out

 

I agree a lot of it has to be the driver, and also the type of driving. My first 2 fillups I only got 25 mpg and was a little disappointed, but I guess I too have to wait it out and see if it gets better. I do only have 350 miles on the clock right now.

 

That is completely unacceptable mileage. This is a tiny engine folks, 1.5 litre. You should be getting over 35 mpg easy. My wife gets 38 mpg highway, 34 city (MT). I get 30 mpg highway, 26 city in my SI. Something just isn't clicking here.

 

Don't be so discouraged. Here are some thoughts:
First, break-in means getting the piston rings mating to the cylinder walls andthat generally takes up to 1000 miles, not 12,000.
Second, how did you drive? Lots of starts and stops. redline engine speeds, lots of throttle 'throw' - pushing the gas pedal up and down - to keep up.
Third, are you sure you filled the gas tank to the same level you started?(many dealers who 'fillup' for you shortchange the fill. So your first tank after 'driving over the curb' is likely to indicate poor gas mileage. And you can do the same to yourself as it is hard to tell when the tank is full. Just check some of the other mpg posters.
Don't give up. You will like the mpg of your Fit; easily twice your pickup's.
cheers.

 

The truth is that you have to average the milage over several tanks of gas. My wife's 07 Fit sport automatic averages 30 MPG mostly in city and freeway driving. When new it got about 25 MPG until it had a couple of thousand miles on the odometer.

Of course your driving habits will affect your milage. Do you take your foot off the accelerator and let the car slow as you approach a red light? Do accelerate above 3,000 RPM when starting from a standstill? Do you drive above 55 Miles per hour on the highway? All of these things will reduce your milage and increase your consumption.

 

Another thing that can affect it also, and I am not sure if this is the same all over the country, but in NY our gas has 10% ethanol in it, so that decreases mileage as well.

 

it's one of three things.

1. you can't count
2. you can't drive
3. it's an automatic

 

is there a really a big difference between an the AT and MT in gas mileage??

 

yes there is

edit: and dude, about your sig, an engine needs to warm up before VTEC works. my brother's del sol VTEC is that way. no vtec until the engine is at operating temperatures

 

My 08 base AT has about 1500 miles on it and Im getting about 210-250 miles per tank, I dont drive that insane, usually never exceed 4000rpms. Ive been patient but its not getting better!

 

My AT has 4800 miles, runs on 87 oct. 10% ethanol from Speedway on Range Rd here in Port Huron, MI (same pump every time, same filling method every time) has never gotten under 31 MPG on a single tank. For any three tank average it has never been less than 32.3MPG on 100 mile daily 50/50 Highway/Stop and go. My single highest tank before the light came was 362 Miles. This was with a week of more highway than stop and go.

During my daily drive I am bound by traffic, but on weekends I run it hard. I take it up to 5k and have fun on the curves. So in my opinion ther whole MT is WAYYYY... more efficient than the AT is BS.

The thing is that I found during test drives with both AT and MT is that the AT turns the engine about 700 RPM slower than the MT at highweay speed. This doesn't translate directly into more MPG because of the eficiency of the MT being higher than the AT, but the engine noise is much lower.

All in all I expect that it all comes out in the wash even. In the EPA tests both are within 1 MPG of each other. While these tests aren't real world, they are the same test for both MT and AT.
