Bönz is right, ethanol is supposed to be in gas and even mandated some states up to 10%.

Why would SA say anything about having ethanol in fuel, 8% - 10% since it should be there? He said that top tier gas would not mix that much ethanol in their gas, but ethanol is mandatory in some states?
I don't think it is gasoline that is the problem. I think the damn engine has issue that they need to fix period.
