In case the link breaks, here's a copy-paste:


TLDR; E85 is acidic, hygroscopic, and more acidic when water-contaminated. Acid in the oil can hurt lubrication ability and corrode metal parts. Since the 86 isn't E85 compatible from the factory, it may not be as resistant to acid wear (citation needed). Frequent oil changes is good insurance when running E85, but likely not necessary in factory flex-fuel fitted vehicles.

From a personal experience, I can smell ethanol in my oil during an oil change. I don't have oil analysis data, but the smell is obvious. The presence of ethanol doesn't necessarily mean it hurt my car, but I'd rather be safe than sorry until we have more data about E85 reliability in the 86.

I know this is an old thread, but if anyone is still concerned with long-term use of E85, this is the most recent UOA I have after using E85 for roughly 40k miles.

If you get the oil hot, ie: 212F, it will last longer ;) . . . with the proviso that the tune isn't overly rich.
