Ethanol is a cleaning agent and is harmful to your engine and its components. It will do considerable damage to your lawnmower, snowblower and any small engine. We are forced to use it in our vehicles and in 10% by volume it will not do a lot of harm. The problem comes when that is increased and I don’t think todays fuels are closely regulated and many times we buy a higher percentage.

The clean fuel program is pushing for a 15% and I feel that is too high and will cause harm. Time will tell how it all works out with the new administration. If you must use ethanol blended fuels in a small engine I recommend the addition of Sea Foam in the fuel.
