That was pretty good. I'd still run 91+ in any car the "recommends it" honestly. Hell my buddy's 4.0 V6 Mustang ran nearly 3 tenths faster in the 1/4 with race gas in it...same 60 ft. and R/T too...who knows.

I'd say run the premium anyways...its like what? $4 more a fill up vs. the low octane junk? Exactly.
