My point was not that 91 octane is bad. It's just that I would not trust any 91 octane called "Premium" at a station that sells it for the same price as 87 octane elsewhere. I have run 91 octane without batting an eye before, but it came from a reputable station. Hell, I'd take 89 from Amoco (or BP as they are called now) before I'd run 93 from Holiday just because it's a better gas.
Everything I have ever heard before was as long as you run 91 or higher, you will be fine. I'm with Craig though, I try to use the best stuff I can find just for the issue of longevity of the engine. I just flipped 153,000 miles and am still running strong.
Just remember, you get what you pay for.
