3.4.2 Engine Oil Recommendation
Kohler Co. recommends API (American Petroleum
Institute) Service Class SG, SH, or SJ 5W-30 synthetic
oil. Synthetic oil oxidizes and thickens less than other
oils and leaves fewer deposits on the engine intake
valves and pistons.
3.4.3 Oil Change Procedure
Allow the oil to cool to a safe temperature before
changing.
1. Follow the instructions in Section 3.3 to access the
generator set oil drain plug, filter, and fill tube. See
Figure 3-4 and Figure 3-5.
2. Drain the oil.
a. Place an oil collection container below the oil
drain and remove the oil drain plug.
b. Allow the engine oil to drain completely.
c. Replace the oil drain plug.
3. Replace the oil filter.
a. Place an oil collection container below the oil
filter.
b. Remove the oil filter by rotating it
counterclockwise with an oil filter wrench.
c. Clean the gasket sealing surface of the oil filter

of the new oil filter.

provided with the filter. Hand-tighten the filter.
Note: Dispose of all waste materials (engine
oil, fuel, filter, etc.) in an environmentally
safe manner.
