I just bought an 03 Boxster with 18" wheels. I put all-season tires on it. 5 speed.

On my first trip to the mountains in Eastern PA, I got 35 mpg going up and 36.5 mpg return. That's mostly highway top up, top down/windows up on the side roads, some AC on returning, highway speeds to 75, mostly 55-65.
Around town, short trip suburban driving, I'm getting 26-27 mpg. I use 92 & 93 octane gas.

The car is EPA rated at 20/29 mpg. I seem to be doing much better, especially on the highway--so the numbers look to be very conservative.

Any other experiences out there? I'm surprised at these numbers, which I verified in several fillups.
