17 to 20 if your lucky, you really shouldnt buy any Z for MPG. The L seris engines last forever though. The L sieres came in the 240, 260, 280, 280zx. Most of the parts are interchangable. Some parts from the 300zx can be used in earlier Z's. Many people do other swaps than just the Z engines, the also put in LS1's, RB25/26, or even short 350's. There is a ton of info out there. Just look up on YOUTUBE they might give you some ideas. If you have anymore questions go ahead and drop me a line or look up Hybridz.org

I have a 71' 240Z , on highway i can get about 23 p/gal. (driving it mellow)A well maintained 280Z i should think would be better as its EFI.
