3. Checking oil level with a dipstick. Unscrew and
remove the dipstick; wipe off oil. Reinsert the
dipstick into the oil fill tube and rest the dipstick
on the oil fill tube. Turn it counterclockwise until
the oil fill cap drops down to the lowest point of
the thread leads. Do not thread the dipstick cap
onto the tube. See Figure 16.
Checking oil level with an oil fill plug. Unscrew
and remove the oil fill plug. The level should be
up to but not over, the point of overflowing the
filler neck. See Figure 17.
4. If the level is low, add oil of the proper type (refer
to Oil Type) and to the correct level. Always check
the level before adding more oil. See Figures 16
and 17.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with the oil level above or below
the correct level.
Oil Disposal
Protect and respect the environment. Dispose of oil
at your local recycling center or municipal collection
center in accordance with local ordinances.
Change Oil
For a new engine, change oil after the first 5 hours of
operation. Thereafter, change oil after every 100 hours
of operation.
For an overhauled engine, use Kohler 10W-30 service
class, SJ or higher oil for the first 5 hours of operation.
Change the oil after this initial run-in period. Refill
with service class SJ or higher oil as specified in the Oil
Viscosity Grades Table (Figure 3).
Change the oil while the engine is still warm. The
oil will flow freely and carry away more impurities.
Make sure the engine is level when filling, checking, or
changing the oil.
Change the oil as follows:
1. To keep dirt, debris, etc., out of the engine, clean
the area around the oil fill plug/dipstick before
removing it.
2. Remove the oil drain plug and the dipstick/oil
fill plug. See Figure 18. Allow ample time for
complete drainage.
3. Reinstall the drain plug and tighten to
17.6 N·m (13 ft. lb.).
4. Fill the crankcase, with new oil of the proper type,
up to the point of overflowing the filler neck.
Refer to Oil Type. Always check the level before
adding more oil.
