+1 to that. I really wish gas companies would drop mid-grade and provide two blends across the country. 89 and 91 octane. A friend of mine was a fuels engineer before he joined the Corps and said that the different blends are basically a money maker and that once you get above 91 octane, you begin to harm your engine. Further, each state has variations that artificially inflate the gas prices.

Star Tron additive really works, not a gimmick.

High octane will not harm engines unless they are specifically designed to run on very low octane, and even then I'm not so sure. I run 93 octane in my FatBoy only because I cannot get anything better, and I wont spring for racing fuel.
In the 80s my Kawie dirt bike specified 95 or higher, but I had only 93 for it. As a kid, I put Sunoco 260 in a '72 125 Penton KTM for years, and that was something like 103 octane. I still have that bike incidentally...
