gas mileage Reply #2 – September 24, 2006, 08:44:47 PM Check your timing, make sure tires are aired up to at least recommended pressures, avoid "jack-rabbit" starts, and such like that.Another thing to check is the brakes, and bearings, making sure that there's not excessive "drag". And don't forget that these cars are kinda chubby...might help to get rid of some weight...spare tires, seats, stereo equipment, wives, girlfriends, buddies...etc etc etc Quote Selected

Most of the mods you do to increase power, can and will increase your fuel economy, if you drive it normally. Quote Selected

gas mileage Reply #13 – September 25, 2006, 04:56:52 AM Years ago my 87' bird w/5.0 got about 20 mpg mostly highway pretty much all stock. Probably could have got better but I had a bit of a lead foot. My opinion but try not to beat it so much and drive like an old lady one tank full and tell us how you do. Quote Selected
gas mileage Reply #14 – September 25, 2006, 05:20:14 PM Well, got mine 2 years ago with 80K on the clock, and now it's just about to turn 106K. It's probably also overdue for a tuneup.However, while I've never had real city driving, I think I've had a worst tankful with local driving of 17.6 MPGBest? Not even 100% highway driving, but I managed to squeeze 29.1 MPG out of one tankful. Runners up are 28.2 and 27.0.I'd say I average 24-25, but that's because I do about 50 to 60 percent highway driving.A tune up, higher-quality tires, and true dual exhausts might get me up to 30 or 31 I'm guessing.FWIW, the window sticker from my car says 18 city, 27 highway.
