said by Beezel:said by myluvnttl78:You are wasting your money, premium gas allow you to advance your timing without pinging and knocking so unless you can advance the timing for better performance then it's waste of money
It also allows you to have a higher compression ratio. I have to run it in my GTI because of the turbo. The boost can get up there rather quickly.
Of course that also, but I don't think the OP 5.0 HO has a higher compression to use premium...
