The D.C. metro area gets oxygenated gas in the winter months... It's supposed to help with emissions, but at the same time, you make less hp, and get lower mileage....
The P5 averages about 29mpg... it's automatic, and the only performance mod is a CAI... of course, it does have one HUGE drawback to it's mileage... ME!!! hehe... When I drive it, mileage drops to around 27....
The RX-7 averages 15 mpg during day to day driving.... If I'm getting into it, mileage drops considerably... about 10mpg.... Don't even ask about track mileage....
