Standard Test Method for
Evaluation of Engine Oils in Diesel Four-Stroke Cycle
Supercharged 1M-PC Single Cylinder Oil Test Engine1
D 6618 – 00
This test method can be used by any properly equipped laboratory, without outside assistance.
However, the ASTM Test Monitoring Center (TMC)2 provides reference oils and an assessment of the test results obtained on those oils by the laboratory. By this means, the laboratory will know whether their use of the test method gives results statistically similar to those obtained by other laboratories.
Furthermore, various agencies require that a laboratory utilize the TMC services in seeking
qualification of oils against specifications. For example, the U.S. Army imposes such a requirement,
in connection with several Army engine lubricating oil specifications.
Accordingly, this test method is written for use by laboratories that utilize the TMC services.
Laboratories that choose not to use those services may simply ignore those portions of the test method that refer to the TMC.
This test method may be modified by means of Information Letters issued by the TMC. In addition,
the TMC may issue supplementary memoranda related to the test method.
