I had been averaging 16.5 for months in San Diego traffic. I put my CAI and Tune on & switched to AMSoil synthetic and drove to Arizona last weekend. I reset the computer before I left and averaged 23 on the freeway and since I have been home, I'm still at 19.2 (with an auto trans). I'm just happy to be over 16.

With my mods, I get 16 around town and 23 on the interstate.

At my last fillup, my GT got 23.324 MPG. That was about 50/50 highway/city.
In the previous fillup before before that, the car got 25.4 MPG.
Most of it, about 70%, was highway driving.
