E85 runs great at 12:1 AFR, and cruises great at 16:1, 17:1 with good ignition.
Corrosion is there but as long as you aren't using shitty cracked up rubber hoses you're fine. The problem is more for when the fuel sits in the lines. If you have a return type system you shouldn't have issues.
E10 doesn't do jack shit to your car as far as damage. It's better than regular 93 without Ethanol, for performance. I bet you're afraid of public toilets too.
