Someone should do a quick test. Grab a bunch of rubber o rings and aluminum and some e-85. Drop the pieces in a Beaker (yeah i said beaker) and let them sit there. see how much damage it actually does to rubber o rings and aluminum over time.

I did do this back in the day actually. I filled a pan with E85 and put a piece of stock DSM (91 era) rubber fuel hose, brass fittings, aluminum, DSM bolt, AN fitting and probably a couple other things I can't think of now and sealed it up with a cover on it. It sat for 2 years until I opened it back up and nothing in there was significantly damaged. Not a very scientific test but it was enough to convince me that it wasn't going to annihilate anything in my fuel system as the internet would have you believe.
