Good luck finding that info. The car fuel vs plane fuel debate has gone on for months without any clear answers. I think enough people have posted in this forum showing the use of plane fuel in cars is more than safe. The guy who picked up the fuel for me is pissed because just a week ago, somebody at HobbyTown told him he MUST use car fuel and he paid over $30 for a gallon. The stuff he picked up for me today was just $16 a gallon. For that much of a price difference, I'll use plane fuel.
