(Test Method)Standard Test Method for Evaluation of Automotive Engine Oils in the Sequence VIII Spark-Ignition Engine (CLR Oil Test Engine)
Standard Test Method for Evaluation of Automotive Engine Oils in the Sequence VIII Spark-Ignition Engine (CLR Oil Test Engine)
SIGNIFICANCE AND USE
This test method is used to evaluate automotive engine oils for protection of engines against bearing weight loss.
This test method is also used to evaluate the SIG capabilities of multiviscosity-graded oils.
Correlation of test results with those obtained in automotive service has not been established.
Use—The Sequence VIII test method is useful for engine oil specification acceptance. It is used in specifications and classifications of engine lubricating oils, such as the following:
Specification D4485.
API Publication 1509 Engine Oil Licensing and Certification System.
SAE Classification J304.
SCOPE
1.1 This test method covers the evaluation of automotive engine oils (SAE grades 5W, 10W, 20, 30, 40, and 50, and multiviscosity grades) intended for use in spark-ignition gasoline engines. The test procedure is conducted using a carbureted, spark-ignition Cooperative Lubrication Research (CLR) Oil Test Engine (also referred to as the Sequence VIII test engine in this test method) run on unleaded fuel. An oil is evaluated for its ability to protect the engine and the oil from deterioration under high-temperature and severe service conditions. The test method can also be used to evaluate the viscosity stability of multiviscosity-graded oils. Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.
1.2 Correlation of test results with those obtained in automotive service has not been established. Furthermore, the results obtained in this test are not necessarily indicative of results that will be obtained in a full-scale automotive spark-ignition or compression-ignition engine, or in an engine operated under conditions different from those of the test. The test can be used to compare one oil with another.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3.1 Exceptions—The values stated in inch-pounds for certain tube measurements, screw thread specifications, and sole source supply equipment are to be regarded as standard.
1.4 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. Specific precautionary statements are provided throughout this test method.

This standard is issued under the fixed designation D6709; 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 (´) 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).
