yep...they get good gas milage. They only run on 93...however you could probably get by with some 89 in a pinch as long as you never went WOT.

I used to get between 15-21 depending on how much I was beating on it around town. On the highway...pshhhh...26+ is the norm. Some Zo6s have gotten nearly 30 mpg logged on the highway. The effiecency is due to many things. Piston design, the very good PCM, but mostly cylinder head design. The chamber is VERY efficient.
