Not saying it can't, didn't or doesn't happen, maybe I should have said varnish instead of sludge. So far we haven't seen any issues, hopefully never will. I did put a gallon of E85 in a container with some random aluminum and rubber parts. Left it sit for almost a year in an unconditioned garage, half of the time with a lid the other half without and found nothing. No corrosion of parts, no brake down to the hoses.

It's wild that some have big problems with it and some have no probs. I fly giant scale gas rc planes and there are a bunch of people that claimed there airplane engines are junk cause of e-85!! Any place sell it on the lake?
