Hmm. I get 22mpg out of my '99 GTP and that's with me driving like a maniac. If I toned it down, I'd probably get 23 or possibly 24 (which would be good considering current gas prices.)
The GTP's require at least 91 octane gas, and I run 93. I've found I actually get better mileage out of the higher octane gas than I do the regular. As for getting better mileage otherwise, a complete tune up, with new plugs/plug wires and air filter will help, and driving with the Performance Shift off will help a little (Although, I rarely drive without mine). And use the cruise control. All in all, 22mpg isn't bad for a supercharged V6 like these.
