1) Make sure it is running at its best
2) use a light foot

The former is easier than the latter.

What is good gas mileage?

If you want a fuel sipper then a V8 is not the answer.

Make sure your car is road worthy, up to date on the tune up items, tires are good and properly inflated and best said earlier "use a light foot".

Actually the Fox isn't too bad on gas at all. I had a 1971 Nova that was getting like 8 miles to the gallon and my father in law's Expedition wasn't much better. So when your light on the gas and getting 16-17 mpg then I'd say it ain't bad. Not to mention you can't run all this performance stuff and expect to get good mileage. If your worried about gas then take it easy most of the time then pound it once in awhile and you will be fine. There is no free lunch...performance=gas eating unless its a turbo 4 banger then it's slightly better. Just my 1.5 cents.

I'm getting mid to high 20's on the highway, mid teens in the city.

One of these days I'm going to get a Megasquirt and lean it out a little at cruise and shoot for mid 30's

for better gas mileage do cold air induction exhaust and retard timing a little you loose a little from retarding timing but i was getting 22 mpg when my car was a daily driver now im lucky to get 14- 16 mpg dam 4.10 gear

I just did regular tune-up stuff....plugs, wires, coil, cap and rotor, oil change. I had a long road trip and got 25MPG. Not too damn bad. New tires probly helped too

I get 25 on the highway and about 17 in town. Not bad for a heavy vert and 2.73 gears. I keep my foot out of it most of the time though.
