Ethanol is here to stay and you'll see it everywhere over the next couple of years. All new engines and fuel systems are built with ethanol resistant hoses and seals. As for additives, run stabil in your last tank of fuel for the year and don't worry. Ethanol is a solvent and will keep the fuel system clean. It only becomes a problem when it gets old. That means 6+ months. If treated for the winter, no worries.
