FUEL SYSTEM MAINTENANCE
When properly maintained, your Honda lawn mower should provide years of trouble-free operation. This includes the fuel system.
However, gasoline can quickly deteriorate, causing starting or running problems and, in some cases, damage to the fuel system. Most
fuel-related problems can be avoided by following the precautions listed below. Fuel system damage and engine performance problems
resulting from deteriorated fuel are not covered by the Distributor’s Limited Warranty (see

Do not use gasoline containing more than 10% ethanol.
A high level of ethanol in gasoline attracts water, and can corrode

If you have fuel left in your storage container at the end of the season, the EPA (Environmental Protection Agency) recommends
adding the gasoline to your car’s gas tank (http://epa.gov/reg5oair/mobile/winter.html), provided your car’s gas tank is fairly full.
