Regular or premium
I know that Chevy recommends premium gas in the 6.2L engine. What do all of you out there use? Is using regular a bad idea?

I can't speak on the new engines, but my 2011 Yukon Denali would ping if I didn't run premium.
The 6.2 LS3 on my wakeboat will run rough enough to throw a service engine code with low octane fuel (it's done it to me three times now - I hate marina fuel).
I would say that there is a reason the owners manual says to use premium.
