IMHO, octane is far more important than the presence or absence of ethanol. Chevy designed all the higher output engines for premium fuel, that is what I'd suggest using.

The coupe runs fine on regular but I always used to put that highest octane Sunoco (93?) gasoline in the convertible and then it wouldn't ping. I can't find it at the closest Sunoco now that I've moved. That and the fact that I'm becoming more and more concerned about ethanol prompted me to fill up with ethanol-free regular. The only source for ethanol-free gasoline here only sells it in regular grade. Anyway, now my engine is pinging going up hills. Should I use an octane boost additive from the local auto parts store? Is there one that anyone recommends?
