i dot believe gas burns any cleaner or anything, i believe e85 helps make more torque or something. i know people with a tune turning frmo gas to e85, adn they mkae more on e85, and dont change anything other than what the engine burns best on. btu yes its just a temp thang. and its cheaper or the smae price as gas round here. much cheaper than permium. which i hope you are running in your whip cause t7 runs best on premium.
way to high to try and reson this shit out, sorry if it dosent make sence
