LUBRICATION
DESCRIPTION
LUBRICANT
CATERPILLAR
Use oils meeting the following engine service classification:
SC and SD (MS - Motor Severe Oils)
CB (Supplement 1 Oils)
CC (MIL-L-2104B Specification Oils)
CD or (MIL-L-2104C)
Use SAE 10W-30, 10W-40 or SAE 30 grade oils for temperatures above
freezing. Use SAE 10W, 10W-30 or 10W-40 grade oils for temperatures
below freezing. Below -23° C (-10° F) it may be necessary to warm the
oil so the engine can be cranked and oil can circulate freely.

I
API classification CC and CD quality oils as used in turbocharged engines and API classification CC/SC quality oils as
used for stop-and-go service are satisfactory for use in naturally aspirated engines.
2
API classification CC/SC and CC/CD indicate that the oil must be blended to the quality level required by both
specifications.
The range of oil quality permitted by the CC classification is so broad that some oils that meet the classification will not
provide adequate protection (varnish and ring sticking) for engines operated in certain applications. For example,
turbocharged engines require the additional protection provided by the CD classification. Engines operated in stop and
go service require the additional protection provided by the SC classification.
3
A sulfated ash limit has been placed on all lubricating oils for Cummins engines because past experience has shown
that high ash oils may produce harmful deposits on valves that can progress to guttering and valve burning.
4
Completely ashless oils or high ash content oils, are not recommended for use In gas engines a range of ash content is
specified.
5
SD or SE may be substituted for SC.
