Standard Test Method for Evaluation of Heavy-Duty Engine Oils under High Output Conditions—Caterpillar C13 Test Procedure
SIGNIFICANCE AND USE
5.1 This test method assesses the performance of an engine oil with respect to control of piston deposits and maintenance of oil consumption under heavy-duty operating conditions selected to accelerate deposit formation in a turbocharged, intercooled four-stroke-cycle diesel engine equipped with a combustion system that minimizes federally controlled exhaust gas emissions.
5.2 The results from this test method may be compared against specification requirements to ascertain acceptance.
5.3 The design of the test engine used in this test method is representative of many, but not all, diesel engines. This factor, along with the accelerated operating conditions, needs to be considered when comparing test results against specification requirements.
SCOPE
1.1 The test method covers a heavy-duty engine test procedure under high output conditions to evaluate engine oil performance with regard to piston deposit formation, piston ring sticking and oil consumption control in a combustion environment designed to minimize exhaust emissions. This test method is commonly referred to as the Caterpillar C13 Heavy-Duty Engine Oil Test.3
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Exceptions—Where there are no SI equivalent such as screw threads, National Pipe Treads (NPT), and tubing sizes.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Annex A1 for general safety precautions.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This standard is issued under the fixed designation D7549; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A

INTRODUCTION
Any properly equipped laboratory, without outside assistance, can use the test procedure described
2
in this test method. The ASTM Test Monitoring Center (TMC) provides calibration and an
assessment of the test results obtained on those oils by the laboratory. By this means the laboratory
will know whether its use of the test method gives results statistically similar to those obtained by
other laboratories. Furthermore, various agencies require that a laboratory utilizes the TMC services
in seeking qualification of oils against specifications. For example, the U.S. Army has such a
requirement in some of its engine oil specifications.Accordingly, this test method is written for those
laboratories that use the TMC services. Laboratories that choose not to use these services should
2
ignore those portions of the test method that refer to theTMC. Information letters issued periodically
by the TMC may modify this test method. In addition the TMC may issue supplementary memoranda
related to the test method.
