Oil Change
Break-In Period Oil Recommendations
Generator set engines may be shipped dry; the oil used
in factory testing having been drained. Before operating
a new set, the engine crankcase should be filled to
specified capacity with a straight-weight oil having a
viscosity appropriate for your particular climate. Do not
use synthetic oils during the first five hours of operation
or the rings may not seat properly. This oil should be
changed immediately after the first five hours of
operation. See OIL TYPE following.
On a new engine, change the oil after the first five hours
of operation and thereafter at 100 hour intervals or 12
months, whichever occurs first, on the 4 kW, and 50
hour intervals or 6 months, whichever occurs first, on the
5 kW.
Replace the oil filter at every oil change.
Whenever possible, drain the oil while it is still warm. To
drain, place container below unit and open petcock
(located directly beneath the dipstick assembly). Allow

adequate time for generator to drain completely.
Remove filter by rotating filter counterclockwise with an
oil filter wrench. After draining, close petcock then install
replacement filter. Before installing replacement filter,
apply a light coating of fresh oil to the rubber seal at the
base of the filter. Add new oil of proper weight and grade
as specified under OIL TYPE following. After restarting,
check the area around the filter for evidence of leakage.
Tighten filter if needed to stop leakage.
High quality detergent oils meeting the requirements of
SAE service class SF are recommended for use in the
Kohler M18 & M20 engines. Straight weight 30 oil is
preferred. If multi-viscosity oil is used, be aware of the
resulting increase in oil consumption and combustion
deposits when used in temperatures above 32° F (0° C).
Base oil weight selection on air temperature at time of
operation. Consult the SAE Viscosity Grade chart (see
Figure 3-4).
