Anyone ever have a gas KNOCK from running 87ish octane gas, but have it stop when you moved up to around 93 octane?

Thanks

Was it like a humming noise when you reved it? What do you mean by 100% octane? Did the knock stop?

Read your owners manual, It will tell you not to run anything less than 92 octane. Personally i run 94 from sunoco. My baby likes that.:D

Is there a difference between Sunoco gaas and gas from other gas stations? Thanks!

I like it better, there is no difference between the gases I think but sunoco is the only one that offers 94 octane, the rest are 93 and below. I dont like gulf though, they just seem so dirty.
