Oil Recommendations
Using the proper type and weight of oil in the engine
is extremely important, as is daily checking of oil
level and changing oil regularly. Failure to use the
correct oil, or using dirty oil, will cause premature
engine wear and failure. Refer to Oil Check/Change
maintenance instructions.
Oil Type
Use high-quality oil that ranks at or above the
American Petroleum Institute's (API) SJ service class.
Select the oil's viscosity based on air temperature at

General Fuel Recommendations
Purchase gasoline in small quantities and store in
clean, approved containers. Use a container with a
capacity of two gallons or less with a pouring spout

eliminate spillage during refueling. To minimize gum

countries using the Research method, it should be 90
octane minimum.
Unleaded gasoline is recommended as it leaves less
combustion chamber deposits. Leaded gasoline may
be used in areas where unleaded is not available and
exhaust emissions are not regulated. Be aware that the
cylinder head may require more frequent service.
Gasoline/Alcohol Blends
Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is approved as a fuel for Kohler
