Cleaning the System of Heavy-Duty
Antifreeze
• Clean the cooling system after used coolant is
drained or before the cooling system is filled with
new coolant.
• Clean the cooling system whenever the coolant is
contaminated or whenever the coolant is foaming.

Fluid Recommendations
General Lubricant Information
Because of government regulations regarding the
certification of exhaust emissions from the engine,
the lubricant recommendations must be followed.
API Oils
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. 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
The performance of commercial diesel engine oils is
based on American Petroleum Institute (API)
classifications. These API classifications are
developed to provide commercial lubricants for a
broad range of diesel engines that operate at various
conditions.
Only use commercial oils that meet the following
classifications:
• API CH-4 minimum multigrade oil
• API CI-4
• ACEAE3
To make the correct choice of a commercial oil, refer
to the following explanations:
API CH-4 – API CH-4 oils were developed to meet
the requirements of the new high-performance diesel
engines. Also, the oil was designed to meet the
requirements of the low emissions diesel engines.
API CH-4 oils are also acceptable for use in older
diesel engines and in diesel engines that use high
sulfur diesel fuel.
Three new engine tests were developed for the API
CH-4 oil. The first test specifically evaluates deposits
on pistons for engines with the two-piece steel piston.
This test (piston deposit) also measures the control
of oil consumption. A second test is conducted with
moderate oil soot. The second test measures the
following criteria: wear of piston rings, wear of
cylinder liners and resistance to corrosion. A third
new test measures the following characteristics with
high levels of soot in the oil: wear of the valve train,
resistance of the oil in plugging the oil filter and
control of sludge.
