Diesel Engine Oil (DEO) (API CI-4 / API CI-
4PLUS)
(1)
These oils have changed from API CJ-4 to API CK-4 in early 2017.
Note: More Perkins engine oils may be available.
Note: Perkins engine oil availability will vary by
region.
Note: The optimal application of the lubricants
depends on the oil quality and the maintenance
practices such as contamination control, tank
management, and general handling practices.
Perkins Diesel Engine Oils
Recommendations
Perkins DEO-ULS and Perkins DEO multigrade oils
are the preferred oils for use in ALL Perkins diesel
engines. Commercial alternative diesel engine oils
are, as a group, acceptable oils. Refer to table 12
below for information.
Table 12
Commercial Lubricants
(1)
Use of API CK-4 / API CJ-4 / ACEA E9 oil specification is subject to ULSD / LSD fuel or fuel with a sulphur content of less than 1000 ppm
(parts per million) (mg/kg)
Note: API engine oil categories are backwards
compatible, except for API FA-4 oil specification.
Perkins DEO-ULS (API CK-4) oil can be used in all
engines with some restrictions related to fuel sulfur
level. Perkins DEO (API CI-4 / API CI-4 PLUS) can
be used in engines that are Tier 3 emissions certified
and prior, and in engines that do not use
aftertreatment devices.

Note: When the recommended Perkins diesel engine
oils are not used, commercial oils that are API CK-4
licensed and/or meet the requirements of the ECF-1-
a, ECF-2, and/or the ECF-3 specification are
acceptable, but are second choice, for use in Perkins
diesel engine.
Lubricant Viscosity
Recommendations for Direct
Injection (DI) engines
Refer to the minimum temperature in table 13 to
determine the required oil viscosity for starting a cold
engine. Refer to the maximum temperature to select
the oil viscosity for engine operation at the highest
ambient temperature that is anticipated.
