•Much of the gasoline sold in the Berkshires contains ethanol. The maximum ethanol content allowed by law for use in outdoor power equipment is limited to 10% (E10). Make sure the gasoline you purchase for your outdoor power equipment contains no more than 10% ethanol. •Ethanol can dissolve varnish and gum deposits that have previously formed inside fuel storage cans or the equipment’s engine. When these deposits become dislodged, they can mix with the fuel and plug small openings and filters within the fuel system. •Ethanol attracts and mixes with moisture in the air, causing corrosion to metal components in the fuel system. If enough water is absorbed, the ethanol and water will settle out of the gasoline blend and settle to the bottom of the equipment’s tank. The layer of gasoline left floating on top has a lower octane level than the original ethanol gasoline blend, which can result in unstable engine operation, power loss and major engine failures. •Since the fuel is often drawn from the bottom of the fuel tank, the engine is drawing in a mixture of ethanol and water with no gasoline and no lubricating oil. This ethanol/water mix is thicker than gasoline and cannot easily pass through the fuel system. This can result in hard starting, unsafe high idle speeds, stalling, and can ultimately lead to engine damage or fuel system failure. Carr Hardware sells Motomix from Stihl, which has gasoline with no ethanol mixed with stihl premium oil to the proper 2 cycle ratio for most small engines.
