I've had my 2008 Fit Sport MT since May08 and now have about 11K miles. I've had as much as 47 mpg, as little as 27 mpg, and usually 31-35. Calculating mileage accurately by filling up the tank is difficult because of the small size of the tank. Small variations each fillup cause big differences in calculated mileage. Still, they do average out over many fillups. Using a scan gauge helps my mileage because I'm always aware of it. Now I coast as much as possible and sometimes I even turn off the engine at long stoplights. The scan gauge is also suspectible to variations in filling up the tank. I guess the new Fits have a built in gauge?

Also, I've noticed the A/C cuts down mileage by around 5 mpg. I guess that little engine has to work hard just to cool off the cabin. Note the A/C works when the defroster is on as well. I think the mileage hit is worst when I'm coasting so now I try to maximize my cooling off (and now defrosting) during my acceleration periods.

Lastly, I noticed a few years ago that my old girlfriend's Audi A3 got much better mileage during hilly driving than flat steady driving (about 25-29 mpg, as I recall). I got over 40 mpg driving from the town of Joshua Tree, CA, up undulating hills to Joshua Tree National Park, then a long steady downhill to the town of Twenty Nine Palms, CA. I think the short uphill bursts were more than made up by the downhill coasting. I've seen this trend, to a lesser degree, in my Fit but haven't repeated the Joshua Tree run. Anyone else ever notice this?

Oh yeah, why does my Fit MT rev about 3500 rpm at 70 mph whereas a Fit AT only has to rev about 2900 rpm and both get about the same mileage?
