Alternative fuel blending has a variety of ethanol blends now approved for sale. E10 and E85 have been the most popular however, now there is E15. E10 is safe for most vehicles and has been blended in gasoline for years.
E15 is now at gas stations. E15 is simply gasoline blended with 15 percent ethanol. These higher ethanol fuels are sold for flex-fuel vehicles, which are designed to burn a mix of up to E85 -- 85% ethanol, 15% gas.
Almost any vehicle can safely burn E10 or E15. But it is suspected of causing premature wear to chainsaws, lawn mowers, boat engines and the like, which is why the small-engine interests are opposing the moving to E15. It’s warned that pumping E15 into any other vehicle is considered "misfuleing" and one can be penalized. Filling a gas can for outdoor power equipment would be considered “misfueling”.
Also the higher the ethanol content the lower the fuel energy per gallon compared to gasoline. The reason it’s important is ethanol if corrosive to rubber and metals. This means that engine components subjected to ethanol at higher blends could see premature failure. Ethanol also attracts water from the air which could settle in the fuel tank and clog the fuel system. If your machine does any sitting for periods of a week or two it would be wise to add a fuel stabilizer to the fuel. This will help with the water residual in the tank.
