I have run 110 & 112 & 114 gas and Alcohol i have not run E85 but for me Alcohol is the way to go i love it because it makes more power and runs cooler and i can get it any time and i change my oil after about 6 races i use brad penn oil it`s green oil and you can boil it in a turkey cooker three or for times before you have to get new oil this is best oil i have used but if you get your carb right and use a lean out valve i don`t have much Alcohol in my oil and let them at the track try to burn me down ha ha ha they can`t and the hot weather don`t hurt the ET as much so good luck
