“I know E85 sure as hell reduces gas mileage.”
It takes a while for the Engine Control Module to recalibrate to E85 but you do get a little more horsepower and I’m in favor of more power. That being said I have the same disagreement about putting food in a gas tank. Ethanol is not good for engines that don’t see a lot of use like chainsaws, pressure washer and lawnmowers.
I only went as far as E40 mixing E85 and E10 to see the effect on gas mileage as it was my engine and was designed to handle higher ethanol concentrations but not to E85. That was enough for me. E15 isn’t cheaper when factoring in fuel system damage and reduced gas mileage.

A little more horsepower than what?
