I've become used to running 93 because of my last (modded) truck. I've been running 93 in my 09 5.7L for the same reason I run Royal Purple oil; to keep it cleaner longer (The dumbest thing is I only use Shell V-Power [mind thing I guess]). The price difference between 89 and 93 is like $2 or $3 for a whole tank AND YOU DO BETTER MILEAGE so what the hell.

Having said that, I'm now wondering is the 93 HURTING the engine? And how?

Maybe I'll try the midgrade next time.
