Using the proper type and weight of oil in the
crankcase is extremely important. So is checking oil
daily and changing oil regularly. Failure to use the
correct oil, or using dirty oil, causes premature engine
wear and failure.

Petroleum Institute) service class SG, SH, SJ or higher.
Synthetic oils may be used. Select the viscosity based
on the air temperature at the time of operation as
shown in the following table.
