owners manual says premium recommended for max performance....not premium required. http://car-owners-manual.com/chevro...nd-operating/recommended-fuel-6-2l-v8-engine/Let me bring it back with some more fun.
I just got a 6.2, and the dealer said I don't need premium, but everything I have read and seen says I need to use 93 gas if possible. We have it all over here so I would.
To be honest I am going to do it no matter what as I don't like using lower grade fuels regardless. But why would the dealer tell me no and don't worry about it?
I like them, trust them and they were a low pressure easy sale. So I was confused when he told me I didn't need to do it, or even really suggest I do.
As for premium gas vs low tier it's just the anti knock agents that are different. I wouldn't say the gas is better quality. So if a car requires it it's necessary so it doesn't knock (high compression motors etc).
We tested higher octane fuel than manufacturers require on the Honda CR-V, BMW M5, Ford F-150, and Dodge Charger to see if it impacted acceleration or MPG.
