What should the average mileage be on an SA22? I'm wondering, so I know what's a good MPG for once I get my car running, so I can figure out what else is wrong with it.

 

in normal street driving a 12a car should be at least 18mpg, more like 18-22mpg.

a gsl-se will get about 2mpg more.



hard driving, it should dip slightly, and on the racetrack you can expect about 10-12mpg

 

I probably wouldn't be doing any hard driving, and I definitely wont be taking it on the track often. I'd probably only race it when the track i work at has their "spectacular drags" (where you can take your car on the track, and race it against other people, to win something). But thats if the track re-opens.
