5. Fill the crankcase, with new oil of the proper
type, to the “F” mark on the dipstick. Always
check the level with the dipstick before adding
more oil.
6. Reinstall the oil fill cap/dipstick.
Figure 6-3. Oil Level Dipstick.
5. If the level is low, add oil of the proper type, up to
the “F” mark on the dipstick. Always check the
level with the dipstick before adding more oil.
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 below the “L”
mark or over the “F” mark on the
dipstick.
Oil Sentry™
Some engines are equipped with an optional Oil
Sentry™ oil pressure monitor. If the oil pressure gets
low, Oil Sentry™ will either shut off the engine or
activate a warning signal, depending on the
application.
Change Oil and Oil Filter
Change Oil
Change oil after every
100 hours
of operation. Refill
with service class SG, SH, SJ, or higher oil as specified
in the “Viscosity Grades” table.
Change the oil as follows:
1. Run engine until warm.
2. Remove the oil drain plug and oil fill cap/dipstick.
Be sure to allow ample time for complete
drainage.
3. Make sure the engine is level when filling,
checking, and changing the oil.
4. Reinstall the drain plug. Make sure it is tightened
to
7.3-9.0 N·m (65-80 in. lb.)
torque.
Figure 6-4. Oil Drain Plug Locations, Oil Filter, and
Optional Oil Sentry™ Switch.
Oil Filter
These engines are equipped with a full-flow oil filter.
See Figure 6-5.
The oil filter helps remove sludge and other
combustion by-products from the oil. It also extends
the oil change interval and cools the oil.

Change Oil Filter
Replace the oil filter
at least every other oil change

. Always use a genuine
Kohler oil filter. Replace the oil filter as follows.
