NOTE: Use a high-quality 15W-40 multiviscosity oil, such
as Cummins Premium Blue®, or its equivalent, in
Cummins® engines. Choose the correct oil for your
operating climate. Refer to Cummins Engine Oil
Recommendations, Bulletin 3810340
Fill the lubricating oil pan with clean 15W-40 lubricating oil
to the low level. Refer to Procedure Procedure 018-017
(Lubricating Oil System in Section V) for common
lubricating oil pan capacities, or by looking up the oil pan
option for the engine serial number on QuickServe
OnLine.
NOTE: When filling the oil pan, use the fill tube on the
side of the engine rather than on top of the rocker lever
cover.
NOTE: If the engine is not equipped with a side-fill, wait
at least 5 minutes before measuring the oil level with the
dipstick to allow the oil to drain to the pan.
Service Tip: If the oil capacity of the oil pan is not known,
fill the lubricating oil pan to the smallest oil pan capacity
listed in Refer to Procedure Procedure 018-017
(Lubricating Oil System in Section V) for the engine being
worked on. Then add 1 quart of oil at a time until it
reaches the high mark on the dipstick. Record the number
of quarts added so that capacity is known the next time
the oil is drained.
Idle the engine to inspect for leaks at the drain plug and, if
replaced, the oil filter seal.
NOTE: Engine oil pressure must be indicated on the
gauge within 15 seconds after starting. If oil pressure is
not registered within 15 seconds, shut off the engine
immediately to avoid engine damage. Confirm that the
correct oil level is in the oil pan.
