I agree that actual ethanol fuel is a waste. Too much energy is used to produce it and it does lower mlg about 10% and provides less power. The 10% stuff is ok though. Messes up my 2 cycle engines though. Doesn't burn properly when mixed with oil.
Ethanol does hurt fuel lines that aren't made for it. Other than that I've never heard any actual fact based claims of engine damage to newer engines that aren't above 9/1 compression. Just fuel line deterioration. maybe debris from the fuel lines gets in the engine.
