Figure 6. Checking Oil Level.
4. Pull the dipstick out and check the oil level.
The oil level should be up to, but not over, the
“FULL” mark on the dipstick. See Figure 7.
Check Oil Level
The importance of checking and maintaining the proper
oil level in the crankcase cannot be overemphasized.
Check oil BEFORE EACH USE as follows:
1. Make sure the engine is stopped, level, and is
cool so the oil has had time to drain into the sump.
2. To keep dirt, debris, etc., out of the engine, clean
the area around the dipstick before removing it.
3. Unthread and remove the dipstick; wipe oil off.
Reinsert the dipstick into the tube and rest the cap
on the tube. Do not thread the cap onto the tube.
See Figure 6.
Figure 7. Oil Level Dipstick.
5. If the level is low, add oil of the proper type, up to
the “FULL” mark on the dipstick. (Refer to “Oil
Type” on page 5.) Always check the level with the
dipstick before adding more oil.

Range
"Full" Mark
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 “ADD”
mark or over the “FULL” mark on the
dipstick.
Oil Sentry™
Some engines are equipped with an optional Oil
Sentry™ oil pressure switch. If the oil pressure drops
below an acceptable level, the Oil Sentry™ will either
shut off the engine or activate a warning signal,
depending on the application.
NOTE: Make sure the oil level is checked BEFORE
EACH USE and is maintained up to the
“FULL” mark on the dipstick. This includes
engines equipped with Oil Sentry™.
Change Oil and Filter, Service Oil Cooler
Change Oil
Change oil after every 100 hours of operation (more
frequently under severe conditions). Refill with service
class SG, SH, SJ or higher oil as specified in the
‘‘Viscosity Grades’’ table (Figure 3) on page 5.
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, or
changing the oil.
Change the oil as follows (see Figure 8):
1. To keep dirt, debris, etc., out of the engine, clean
the area around the oil fill cap/dipstick before
removing it.
2. Remove one of the oil drain plugs and the oil fill
cap/dipstick. Be sure to allow ample time for
complete drainage.
3. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.) torque.
4. Fill the crankcase, with new oil of the proper type,
to the “FULL” mark on the dipstick. Refer to “Oil
Type” on page 5. Always check the level with the
dipstick before adding more oil.
5. Reinstall the oil fill cap/dipstick and tighten
securely.
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 “ADD”
mark or over the “FULL” mark on the
dipstick.
