An American National Standard
Designation: D 6709 – 04
Standard Test Method for
Evaluation of Automotive Engine Oils in the Sequence VIII
1
Spark-Ignition Engine (CLR Oil Test Engine)
This standard is issued under the fixed designation D 6709; 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
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This test method can be used by any properly equipped laboratory without outside assistance.

However, the ASTM Test Monitoring Center (TMC) offers a very valuable service to the test
laboratory; the Center provides reference oils and an assessment of the test results obtained on those
oils by the laboratory (see Appendix X1). 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 American Petroleum Institute (API)
imposes such a requirement, in connection with several 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 theTMC. In addition,
the TMC may issue supplementary memoranda related to the test method (see Annex A3).
