Figure 3-1. Oil Level Range.
4. Add the proper type of oil if the level is low. Al-
ways check the level with dipstick before adding
more oil.
NOTE:
Never operate the engine with the oil level
below "1" mark or over "F" mark on
dipstick.
Oil Sentry™
Some engines are equipped with optional Oil Sentry™
oil pressure monitor. Oil Sentry™ will either stop the
engine or activate a "low oil" waming light, if the oil
pressure gets low. Actual Oil Sentry™ use will vary
depending on the engine application.
NOTE:
Oil Sentry™ is not a substitute for checking oil
level BEFORE EACH USE.
Make sure the oil
level is maintained up to the "F" mark on
dipstick.
CHANGE OIL
For a new engine, change oil after the first 5 hours of
operation. Thereafter, change oil as specified in the
"Oil Change Intervals" table.
For an overhauled engine or those rebullt with a
new short block, use straight 30-weight Service
Class SF or SG oil for the first 5 hours of operation.
Change the oil after this initial run-in period. Thereaf-
ter, change the oil as specified in the "Oil Change In-
tervals" table.
Drain oil while the engine is still warm from operation.
The oil will flow more freely and carry away more im-
purities. Change oil as follows:
1. Remove the oil drain plug and dipstick. Refer to
Figure 3-2. Tilt the engine slightly towards the
drain hole to obtain better drainage.
