Regular or premium
I know that Chevy recommends premium gas in the 6.2L engine. What do all of you out there use? Is using regular a bad idea?

I would use the minimum recommended octane as specified by GM.
My 1970 Mustang required 98 Octane and best available was 94 then 92. Probably ran a lot better in 1970.
