fuels (called gasohol or using ethanol or methanol)
can attract moisture which leads to separation and
formation of acids during storage Acidic gas can
damage the fuel system of an engine while in storage
To avoid engine problems, the fuel system should be
empty before storage for 30 days or longer Refer to
"Storage" section of this manual for details Use fresh
fuel each season.
Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may result
