Just wondering if anyone has done a road/fuel test on their Fit for low mpg at the dealership? Is this test covered under the warranty?
My 2012 Fit Sport has been getting 18-22 mpg mostly city driving ever since I bought it...

 

check your tire pressure, run 34-36psi at a minimum

stock dunlops are rated at 40psi max, and that is what my fronts are currently. backs are at 37psi currently

These pressures are checked after the car has been driven awhile, tire pressure increases with car use (heat expansion)

I usually average 27mpg with 80% city and many many minutes of idling each day

EDIT its Texas, so the AC is on 100% of the time nowadays

 

Take the road down to San Jose (do you know the way?) Loaf along at 65mph. Even with the A/C on you should be in the low-mid 30s (mpg). Report back.

Clear the trip miles before starting out so the avg mpg display is initialized as well.

 

You need about 6,000 miles on your Fit before it gets better MPG.

 

I haven't noticed any difference in mpg after 6k miles. After 500 miles , maybe a little improvement. There is nothing special about a Honda Fit that should require 6000 miles for break in.

Just my experience on the Fit compared to other cars I have owned from new.

If you are doing most of your driving on Frisco streets that mpg is probably about average. I live in a small city with some hills, I have to go through 18-20 stop lights and some stop signs a 11mi drive I frequently use. If I use that run and nothing else I get about 24-27mpg. On extended runs only I get 36-39 mpg. That will vary based on how many hills I encounter.

Car is A 2011 Fit Sport with automatic.

Thanks for the replies guys.
I have a little over 8,000 miles on my Fit.
The gas mileage did slightly improve after my first oil change since the dealership used synthetic oil.
Even though I live in SF, isn't getting 18-22mpg really low especially since I don't use AC at all in this city?
It seems the majority of the members here are getting like 27-30 mpg city driving with a heavy foot.
I guess I'll try setting all my tires at 35psi and report back.

 

Do your own test: Reset the trip odometer (resets the AVG MPG display). Take an hour's drive down the interstate (I280). 30 minutes each way. Drive leisurely. If you're below 28mpg I'd say have it checked.

As long as you're at or a couple pounds above Honda's recommended pressure (not the max pressure embossed on the side of the tire) you won't see a big (or even noticeable difference) increasing the tire pressure.

MPG of 18-22 is below average for city driving, but then you don't live in an average city. Take it on the highway for a bit.

 

How long are your trips on average? If you make lots of short trips (which, with 8000 miles accumulated in a year or so, certainly sounds possible), you'll get relatively abysmal gas milage because the engine is spending a lot of time operating when it's not fully warmed up. The terrain of San Fran is hardly typical of many cities, too, which can certainly also be a consideration.

I concur with Steve's suggestion. Take a longer trip at a steady 65-70 mph and see how the car does.
