I read in the owners manual that they do NOT like ethanol blend if possible. Alcohol is very corrosive to the fuel system. I'm running 91 octane Shell with the new V-Power additives (better/more detergents) and have no problems with knock or performance. I would rather give up on octane (above 91) if it is at the price of adding any alcohols. Try some 91+ and see if there is a difference. Good luck.
