Unless the engine is higher compression the e85 won't do u much.Hmm.....just thinking if this would even make sense..Idk if I want to be in the middle of no where with no e-85 either. It is so appealing with such a high octane rating though. Getting pretty common. Tossing ideas around. I am thinking of dropping a ultima 124" el bruto touring engine in and I know it would run kick ass on e-85!!
