You guys really need either a tune up or learn to drive. I get 28.6mpg on the hwy and about 22 in the city. I am the high side of fuel economy for the mustangs. Most people get 18-24mpg.

I get about 13-15 mpg on short city trips. If I'm on it a lot, it will dip down to 12 or so. I'm sure if I'm on it all the time it will get even worse.

I get about 17-20 mpg on the highway w/cruise control set at about 75 mph.

Car is a stock 2003 GT vert with automatic transmission. About to change the fuel filter this weekend.

I'd love to get close to 30 mpg, but for some reason, I don't see that ever happening.
