Because of the alcohol/gasoline mixture, E85 has a rough estimate octane rating of between 105-113 octane depending on the mixture. Also the alcohol in E85 has a HUGE cooling property associated with it as well. E85 has a lot of the cooling properties that you also find with Water Meth Injection. (www.enginebasics.com/methinjection) It is great at lowering intake temperatures, lowering engine block and head temperatures, and basically doing everything that can help suppress detonation. So with E85 being SO amazing, why don’t we all convert over and start using it?

E85 burns much cooler, thus helping to keep Oil (And other) temps down. and due to that property, it also gives you the ability to play with the timing more without the risk of detonation.
