NOTE: Use a high-quality 15W-40 multiviscosity
lubricating oil, such as Valvoline Premium Blue®, or its
equivalent, in Cummins® engines. Choose the correct
lubricating oil for your operating climate as outlined in
Section V.
Fill the engine with clean lubricating oil to the proper level.
Refer to Procedure 018-017 in Section V.
NOTE: Total system capacity assumes lubricating oil pan
plus lubricating oil filter.
Some applications use a slightly different lubricating oil
pan capacity, and all lubricating oil quantities must be
adjusted accordingly. Contact a local Cummins®
Distributor if there are any questions.
The oil capacity for the engine can also be found by
entering the engine serial number in Quickserve® Online.
(See section E of this manual to locate the ESN) Click on
the "Parts" section , and select the Oil Pan. A description
of the oil pan used on the engine, including fluid
capacities, will be displayed.
Service Tip:
If the oil capacity of the oil pan is not known, fill the
lubricating oil pan to the smallest oil pan capacity. Refer to
Procedure 018-017 in Section V. 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.
