    how do i improve my gas mileage? i have a 1998 Pontiac Grand Prix 3.8 v6.?

    I would start with a tune up if you haven't done it in a while. Plugs, wires/cop's?, clean the MAF, air cleaner, and the throttle body. Oil change, good tires ect... Another way to improve it would be to treat your gas pedal as if it has a egg under it.
