Why don't you edit it then.

well, you're going to get better mileage if you drive exclusively on the interstate compared to driving around town.

coming back from charlottesville one day i got about the same as you, and that's with 3.73s. it wasn't the stp if that's what you're getting at.

Most I have ever gotten on a tank in my 01 is 330. Strictly freeway driving. In everyday stop and go, its about 220-240. I might try the STP to see if it helps.

i guess my car is a gas mileage freak. On a whole tank with nothing but highway i can get 450+ miles on my 96 3.8. I usually average between 32-34 on the highway and about 24-26 in town.

After I used an intake cleaner, injector cleaner and new air filter my MPG jumped up about 90 miles more per tank. I was getting about 215 miles and now I get around 300 with 50/50 hwy and city driving. Not to bad for the way I drive

i average 27MPG doing mostly backroad driving, which does include some stop-and-go traffic due to lights and stop signs. i do little city driving but i also like to use my A/C.

[BobbyZ72]

I average about 26, going 70 mile an hour, on open roads, with the a/c. Car is all stock.

All highway, doing about 85-90, with the AC on, I get about 400 miles per tank.
