ASTM D6709-14

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D6709 − 13 D6709 − 14
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 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 the TMC. In addition,
the TMC may issue supplementary memoranda related to the test method (see Annex A3).
1. Scope*
1.1 This test method covers the evaluation of automotive engine oils (SAE grades 0W, 5W, 10W, 20, 30, 40, and 50, and
multi-viscosity 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
multi-viscosity-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.
1.5 This test method is arranged as follows:
1
This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products Products, Liquid Fuels, and Lubricants and is the direct responsibility of
Subcommittee D02.B0.01 on Passenger Car Engine Oils.
Current edition approved May 1, 2013May 1, 2014. Published May 2013May 2014. Originally approved in 2001. Last previous edition approved in 20112013 as
D6709 – 11.D6709 – 13. DOI: 10.1520/D6709-13.10.1520/D6709-14.

Until the next revision of this test method, the ASTM Test Monitoring Center will update changes in this test method by means of Information Letters. Information Letters
may be obtained from the ASTM Test Monitoring Center, 6555 Penn Avenue, Pittsburgh, PA 15202-4489, Attention: Administrator. This edition incorporates revisions in all
Information Letters through No. 10-1.13–1.
