Terminology
Certain abbreviations follow the nomenclature of
"SAE J754". Some classifications follow "SAE J183"
abbreviations, and some classifications follow the
"EMA Recommended Guideline on Diesel Engine
Oil". In addition to Perkins definitions, there are other
definitions that will be of assistance in purchasing
lubricants.
Refer to Perkins Diesel Engines Fluids
Recommendations, M0113102 for additional
information that relates to oil.
Engine Oil
Commercial Oils
NOTICE
Perkins require the use of the following specifica-
tion of engine oil. Failure to use the appropriate
specification of engine oil will reduce the life of
your engine.

Oil Specification
Preferred Oil Specification
Perkins DEO-ULS (API CK-4)
Perkins DEO (API CI-4 / API CI-4
PLUS)
(1) Use of API CK-4 / API CJ-4 / ACEA E9 oil specification is sub-
ject to ULSD / LSD fuel or fuel with a sulphur content of less
than 1000 ppm (parts per million) (mg/kg)
API CI-4 Plus provide two design improvements over
API CI-4 oil specification, soot viscosity control and
product shear stability.

affected by the use of biodiesel. Use oil analysis to
monitor the condition of the engine oil. Use oil
analysis also to determine the oil change interval that
is optimum.
Note: These engine oils are not approved by
Perkins and these engine oils must not be used:
CC, CD, CD-2, CF-4, and CG-4.
Lubricant Viscosity Recommendations
for Direct Injection (DI) Diesel Engines
The correct SAE viscosity grade of oil is determined
by the minimum ambient temperature during cold
engine start-up, and the maximum ambient
temperature during engine operation.
Refer to illustration 38 (minimum temperature) to
determine the required oil viscosity for starting a cold
engine.
Refer to illustration 38 (maximum temperature) to
select the oil viscosity for engine operation at the
highest ambient temperature that is anticipated.
Generally, use the highest oil viscosity that is
available to meet the requirement for the temperature
at start-up.
Illustration 38
Lubricant Viscosities
Supplemental heat is recommended for cold soaked
starts below the minimum ambient temperature.
Supplemental heat may be required for cold soaked
starts that are above the minimum temperature that
is stated. The requirement also depends on the
parasitic load and other factors. Cold soaked starts
occur when the engine has not been operated for a
longtime. This interval will allow the oil to become
more viscous due to cooler ambient temperatures.
