I used to get almost 32 miles per galloon (City/Highway). Now I don't know what's happened to my fit that it doesn't go higher than 22 MPG. It really sucks if you have a Fit like this!

I changed the air cleaner but it didn't help. The mileage is 8300. Does any body know where the problem can be from?

Thanks in advance...

 

Flat tire? Really jacked up alignment? Siezed brake caliper? wtf that's a huge drop.

My last oil was something too thick the dealer put in, and it was slightly overfull. That really killed my mileage.

I take about a 8-10 mpg hit anytime the air gets below 40F myself. They had to get air from the fender... I sometimes cheat by taking the rubber snorkel off if it's cold out.

 

I must say I've never gotten more than 240 miles on a full tank of gas with my 09 Fit Sport. My gas light normally comes on around 220 miles or even less at times. I barely have over 9000 miles on it so I don't know why my Fit is a little gas guzzler.

 

Wow that's utterly terrible. A CR-V usually gets better mileage than that.

Let's start with the proverbial question: what was the break in like

Then, tranny type, average daily distance and typical cruising speed, and factor in typical shift rpm and throttle load. Then, other variables.

Myself as an example-- 08 fit, stick, strict gentle break-in without long trips or heavy loading, commute 2.5 miles one way at about 30 mph avg with one stop, with 60 miles round trip to church and shop on sunday usually going 55 mph on that, typical shift at 3000-3200 with throttle load that gets up to 60 in under a half mile. OEM tires at 37 pounds, mobil1 5w20 oil halfway between the marks, OEM MTF in the tranny, no exterior mods, passenger weight on sunday 700# between the 3 of us.

I've never gotten under 31 mpg on a tank since I bought it.

Thing that sucks about this car, if you accelerate it fairly quickly like everyone else likes to, the mileage really takes a dump. My sis's old y8 auto civic, she beat the crap out of that car and still got 30+.

 

No, I'm pretty sure tires are not flat, they are almost 4psi above what the manual says. But good point, I haven't checked to see how the oil is, maybe that's too thick or more than enough. But if it was because of oil, why did it happen 2000 miles after 5000 miles service(that was when they did the oil change)?!

 

I don't doubt your experience, but I'm on my second Fit (2009 m/t Sport) and I'm getting really good mileage!

My '07 Fit averaged 37.4 mpg over its life.

The new one is averaging 37.8 so far after 4 months. My low fuel light comes on at 360 to 370 on the tripmeter.

I keep my tires at 40 psi and I'm now running 205/50/R16 Goodyear Assurance Fuel Max tires (which may make ~1-2 mpg difference).

I drive 50/50 city/hwy, maybe 1 short trip per day (<5 mi.) but my work commute is 30 miles.

Your car has to have a mechanical problem or you have lots of short driving trips when the car doesn't have a chance to warm up.

Is most of your driving stop-n-go? That could be it.

 

Something's gotta be goofy with those cars. I get to work just as the cold light turns off everyday and I still have a lifetime mileage of 35.2 mpg.

Oil that's too high a viscosity doesn't have THAT big an effect. I was down around 31-33 mpg for a while while the dealer oil was in, a drop of 2-3 mpg, and it was mildly overfilled to boot. Once it got HOT like on a long trip it had no effect, it was just the cold conditions.

Justsofit, that's a warranty issue for you if it's something mechanical. I wouldn't let it go.

 

I'm in my first Fit, '09 Sport AT, got 15,000 mi. on it and getting about 34/city 38/hwy...sometimes 40+/hwy. I would agree with Polaski, this sounds like an issue your dealer should be aware of soon. Good luck

 

I was in the same boat for a while. I think it was because I was a little bit of a lead foot and that I travel over a small mountain 2 times daily on my trip to work. What I am finding is that this engine seems to have a time when it seems weak and if you accelerate at the wrong time going up hill it can kill your mileage in a hurry. If you can see my cleanmpg profile you will see what my tanks look like. My break in was a little rough because I had 2 or 3 trips to VA which was about 250 miles 1 way. I went back to the basics of hypermiling and am now getting around 40 on the scanguage daily.

 

lead foot and lots of sitting in traffic will kill MPG.

 

I bought this car used like 6 months ago. It had 88,000 miles when I got it. I had my friend do a tune up for me because he's a mechanic like 4 months ago. ever since I got my car, I've been getting 25-27 mpg. only one time where I got 30 mpg. I really don't know what to do or where I can take it for someone t diagnose this problem. weather is not an issue for me since I live in Orange County, CA. I pump 87 for gas because gas is expensive. could that be the reason why I'm getting so little mpg?? thanks!

 

Welcome to the freakworld - lots of help here.

What sort of tune up did your friend do for you?
How do you drive it?
What's the psi your running in the tires?
What tires do you have?
Lots of things can/will effect mpg.
Fuel choice is one, but not that big of a one.

Others will chime in I'm sure.

thanks!

I changed spark plugs, oil change, air filter, fill up all the liquids needed
I have no idea what my psi for my tires are and i have bfgoodrich tires.

I haven't had this car for long and even when I first got it I never really got 30+ miles.

When I pump full tank, the light goes on after 225 miles

I keep thinking that the guy before me ruined my MPG
I'm pretty car noob so hopefully I can learn a thing or two here

 

If you have an automatic transmission and live in Southern California you can expect to get less fuel mileage than someone with a manual transmission that drives on roads with less traffic than you have to deal with... There have been a few people here from your area that have gotten lower fuel mileage than you are getting... I would try driving with a very light right foot, keeping enough room between yourself and the car in front of you so you aren't having to hit the brakes as often only to have to accelerate back up to speed.. Just maintaining as consistent speed as possible helps a lot with mileage and your car will last longer also.

 

I get a consistent 30 mpg US or 7.8 L/100km. I do 50/50 city /hwy but on hwy I drive too fast for good mileage at around 75mph.

I find my mileage doesn't vary that much between summer and winter.

 

Fill your tank to top, but not overfill. You should take it on a long trip where you won't encounter too much traffic. I suggest 55 mph highway speed. Do this a few times on the trip and calculate your MPG. Use the driving techniques described above... no fast starts and use steady driving, maybe with the cruise control. I think you need this baseline to see what the car can do in the most ideal conditions. Heavy traffic and constant changes will kill MPG.

 

amy Like einstein said, you need to get to know your car. All good tips given so far. You might start with setting the tire pressure to 36psi all around. If you don't have a tire pressure gauge you should get one. The ones on those air machines are not good to go by. A dial gauge is good, local autozone has them.

Tires in good shape, tread wise? If you think you'll need to replace them soon, start a new thread and ask here for suggestions.

Next is to start keeping track of mile/gallons used and calculate the MPG. Use the same station for fill-ups but more important fill constantly each time to get accurate results. I fill to two clicks on the pump.

It really does boil down to how you drive it. Fit economy is all about that.

Many folks have seen MPG increases by doing the Idle Learn Procedure.


Do a SEARCH to find out how...it only takes 15 minutes (but you will need your radio security code to reset the radio)

 

If it were my car, I would be checking the spark plug gap, valve clearances and cleaning the MAF (especially if you are using anything but a stock air filter). I would also be checking air pressure in the tires and having the alignment checked.

 

If there is a problem after the easier check, I agree, but I think the simpler stuff would be the first route before what you suggest.... and it doesn't cost anything.
