Oil Recommendations
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.
Before each start, make sure the crankcase is filled
with proper type and quantity of oil.
Oil Type
Use high quality detergent oil of API (American
Petroleum Institute) service class SG or SH. Select
the viscosity based on the air temperature at the time
of operation as shown in the following table.
Straight 30-weight (Kohler "Magnum") oil is
preferred. SAE 10W-30 oil is not recommended
above 32°F. Using this oil substantially increases oil
consumption and combustion chamber deposits.
NOTE: Using other than service class SG or SH oil or
extending oil change intervals longer than
recommended can cause engine damage.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.

page 7 for detailed oil check, oil change, and oil
filter change procedures. Figure 2. Viscosity Grades Table.
