Licensing
The Engine Oil Licensing and Certification System by
the American Petroleum Institute (API) is recognized
by Perkins. For detailed information about this
system, see the latest edition of the “API publication
No. 1509”. Engine oils that bear the API symbol are
authorized by API.

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 Specification” topic (Maintenance
Section).

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.

Engines Operating on Biodiesel
Refer to this Manual Fluid Recommendations, “Fuel
Specification” for the required service interval for
operating with Biodiesel.
Engines Operating on High Sulfur Fuel
Refer to this Manual Fluid Recommendations, “Fuel
Specification” for the required service interval for
operating with high sulfur fuel.
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 21 (minimum temperature) to
determine the required oil viscosity for starting a cold
engine.
Refer to illustration 21 (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.

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 for aperiodof time. This
interval will allow the oil to become more viscous due
to cooler ambient temperatures.
