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
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. Failure to use the appropriate speci-
fication of engine oil will also reduce the life of
your aftertreatment system.
Table 13
Classifications for the 854 Industrial Engine
Oil Specification
API CJ-4
ACEA E9
ECF-3
API CJ-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
Maintenance intervals for engines that use
biodiesel – The oil change interval can be adversely
affected by the use of biodiesel. Use oil analysis in
order to monitor the condition of the engine oil. Use
oil analysis also in order 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
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 33 (minimum temperature) in
order to determine the required oil viscosity for
starting a cold engine.
Refer to illustration 33 (maximum temperature) in
order 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 33
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 occur when the engine
has not been operated over 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 in order 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 in
order to help provide finished oils with performance
characteristics that meet industry standards.
