E-15 Fuel's Harmful Effects on Briggs & Stratton Engines

Is the use of E-15 fuel harmful to Briggs & Stratton engines?

Briggs & Stratton advises outdoor power equipment users to be aware of a new fuel with a higher level of ethanol that will harm small engines. Recently, the Environmental Protection Agency (EPA) approved higher levels of ethanol (E-15 or 15% Ethanol) in gasoline for use in only 2007 and newer automobiles and light trucks.

All Briggs & Stratton small gasoline powered engines are designed to run on up to E-10, or up to 10% ethanol. Use of higher levels of ethanol will affect engine performance and longevity, permanently damage the engine and void manufacturer’s warranty. The Operator’s Manual clearly explains what fuels can be used to ensure a properly functioning product. Consumers should also pay close attention to the gas pumps at local filling stations. Some may offer both E-10 and E-15 or have blender pumps that dispense mid-level ethanol fuels for “flex-fuel” automobiles.
