Figure 9. Dipstick and Oil Fill.
4. Remove the dipstick and check the oil level. The
oil level should be up to, but not over, the F mark
on the dipstick. See Figure 10.
Figure 10. Oil Level Marks on Dipstick.
5. If the level is low, remove the cap from the valve
cover and add oil of the proper type, up to the F
mark on the dipstick. (Refer to Oil Type on page
4.) 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
™
Most engines are equipped with an Oil Sentry
™
oil
pressure switch. On pressure switch equipped
models, if the oil pressure decreases below an
acceptable level, the Oil Sentry
™
will either shut off
the engine or activate a warning signal, depending on
the application. See Figure 11.
Figure 11. Oil Sentry
™
Pressure Switch.
NOTE: Make sure the oil level is checked BEFORE
EACH USE and is maintained up to the F
mark on the dipstick. This includes engines
equipped with Oil Sentry
™
systems.
Change Oil and Filter, Service Oil Cooler
Change Oil
Change oil seasonally or every 150 hours of operation,
(more frequently under severe conditions). Refill with
service class SJ or higher oil as specified in the
Viscosity Grades table (Figure 2) on page 4.
Change the oil while the engine is still warm. The oil
will flow more freely and carry away more
impurities. Make sure the engine is level when filling,
checking, and changing the oil.
Change the oil as follows (see Figures 12 and 13):
1. To keep dirt, debris, etc., out of the engine, clean
the area around the oil fill cap, dipstick and one of
the drain plugs.
2. Remove one of the oil drain plugs, oil fill cap, and
dipstick. Be sure to allow ample time for complete
drainage.
3. Reinstall the drain plug. Make sure it is tightened
to 21.4 N·m (15.7 ft. lb.) torque.
4. Fill the crankcase, with new oil of the proper
type, to the F mark on the dipstick. Refer to Oil
Type on page 4. Always check the level with the
dipstick before adding more oil.
5. Reinstall the oil fill cap and tighten securely.
Reinstall dipstick.
