Ethanol and Two-Stroke Cycle Engines: Impacts of an Alternative Fuel in Small Engines

By: Matthew Veal

Because ethanol has different combustion characteristics than gasoline, some people suggest it will cause harm to two-stroke engines found in all-terrain vehicles (ATVs), lawn and garden equipment, and marine engines. Two-stroke engines require an oil and gas mixture for a fuel source, and the oil and gas are mixed in a ratio specified by the engine manufacturer. Fortunately, the concern with ethanol blended fuels is primarily associated with older engines. The majority of engine manufacturers have now designed their engines to run on E-10 blends (10% ethanol, 90% gasoline), but some precautions still remain. This bulletin will discuss the reasoning behind these precautions and why owners of some equipment powered by two-stroke engines may have concerns.
