I would never run it for one simple reason... As a mechanic, who does a lot of performance cars, i have seen and smelled things that do not seem right. First thing i noticed about E85 is the smell. Run E85 for a entire oil cycle, 3000 miles or so, then change the oil. It smells stronger then a McDonalds deep fryer. Second, spark plugs. They run a whole different color then i have ever seen. I can't even begin to describe that. What does the oil smelling like a deep fryer tell me? Tells me the fuel is getting past the rings and into the oil system, and a lot of it is. Gasoline is a corrosive, destructive, sneaky get-out-of-any-tiny-hole liquid, so E85 being harder to contain under pressure tells me it is too thin. I have spoken to many people who have run it, and most switch back to race fuel when their engines let go. It makes loads of power, but has yet to be tested long term (20+ years). I would never dream of running it personally, despite the added power. Just my $.02
