wow, only 12.5% nitro, huh? I woulda guessed it had more than that. Thats okay, though, for now. what I really need to know about is the oil, though. I know it is intended for aviation use, so I want to be sure that I am not damaging my hotter-running buggy engine due to lack of lube. The 12.5% nitro explains why I had suck a large power increase with my friend's 25% race blend fuel!! It was a noticable difference.
