Figured I would chime in now. Ive been running a mix of 30% E85 and 70% 91oct now for two years. I love it because I run 12.3:1 compression with no knock even on hot summer days. Also even though the car is tuned for this mix i can use straight 91oct if i get stuck too far from a station with e85. Also the car motor seems to run cooler and parts such as heads and pistons remain cleaner. FYI, modern cars, 90's and up, have fuel systems that are compatible with ethanol even if they arent rated for it. These vehicles dont use straight rubber like older cars. New fuel systems have chemical and alcohol resistant hoses. Ive used my stock fuel system with no issues. Only difference was bigger injectors which i already had due to my previous mods. E85 is a great fuel for high performance vehicles, too bad its in limited supply here in socal.
