Fluid Recommendations
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. Recommended oil viscosities can be
found in this publication, "Fluid Recommendations/
Engine Oil" topic (Maintenance Section).
Engine Oil
Commercial Oils
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.
Table 34
Classifications for the 400J Industrial Engines
Oil Specification
CK-4
ACEA E9
ECF-3
API CK-4 and ACEA E9 oil categories have the
following chemical limits:
• 0.1 percent maximum sulfated ash
• 0.12 percent maximum phosphorous
• 0. 4 percent maximum sulfur
The chemical limits were developed to maintain the
expected life of the engine.
Maintenance intervals for engines that use
biodiesel – The oil change interval can be adversely
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, CG-4, CH-4, and CI-4.
Lubricant Viscosity Recommendations
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.

NOTICE
Refer to illustration 42 (minimum temperature) to
determine the required oil viscosity for starting a cold
engine.
Refer to illustration 42 (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 42
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, depending on the parasitic load and other
factors. Cold soaked starts to occur when the engine
has not been operated for a period of time. This
interval will allow the oil to become more viscous due
to cooler ambient temperatures.
Aftermarket Oil Additives
Perkins does not recommend the use of aftermarket
additives in oil. It is not necessary to use aftermarket
additives to achieve the engines maximum service
life or rated performance. Fully formulated, finished
oils consist of base oils and of commercial additive
packages. These additive packages are blended into
the base oils at precise percentages to help provide
finished oils with performance characteristics that
meet industry standards.
