Brace yourselves for a myriad of fuel system problems with increased Ethanol content in your gasoline, your fuel mileage will decrease also. Lots of information on the web about negative effects. Here in Canada and throughout most of the USA it is no longer possible to purchase gasoline at filling stations that hasn't been laced with a minimum 10% Ethanol.
