Engine Oil Specification
Note: Use the highest oil viscosity that is available to
meet the requirement for the temperature at start-up.
If ambient temperature conditions at engine start-up
require the use of multigrade SAE 0W oil, SAE 0W-
40 viscosity grade is preferred over SAE 0W-30.
Note: 10W-30 is the preferred viscosity grade for the
following diesel engines when the ambient
temperature is above −18° C (0° F) and below 40° C
(104° F).

(1) Commercial oils of viscosity grades that are not included in this table may be used, if the oils are per ECF specifications. Commercial oils are
second choice.

Commercial multi-grade oil alternatives must claim at
least one of the following Perkins specifications:
ECF-1-a, ECF-2, ECF-3, API CK-4. Non-Perkins
commercial oils are as a group an acceptable choice
of oils.
Aftermarket Oil Additives
Perkins does not recommend the use of aftermarket
additives in oil. Aftermarket additives are not
necessary to achieve the maximum service life of the
engine or rated performance of the engine. 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 performance
characteristics that meet industry standards.
There are no industry standard tests that evaluate
the performance or the compatibility of aftermarket
additives in finished oil. Aftermarket additives may
not be compatible with the additive package of the
finished oil, which could lower the performance of the
finished oil. The aftermarket additive could fail to mix
with the finished oil and produce sludge in the
crankcase. Perkins discourages the use of
aftermarket additives in finished oils.
To achieve the best performance from Perkins
engines, conform to the following guidelines:
• At the specified interval, service the engine. Use
appropriate new oil and install an appropriate new
oil filter.
