Gas Grade
i am used to driving cavaliers and such, so i was curious what type of gas do u use in your mustangs?
its a 5.0, do they need 91 octane? or is the cheap stuff ok to use?
some cars need premium, and others its a waste to put in premium so what do you use?

I run regular old 87 octane the majority of the time. That's all it calls for in the owners manual. Every once in a while I blow a tank of 94 through her though. She's a stocker, so why bother with the extra expense?

Only the '96+ Cobras/Mach 1s are supposed to run premium, I run regular in my 5.0 with 12deg of timing, ran it with 14 deg of timing a few years back too, no problems, I always run premium in my Cobra though.
