ASTM D8111-18

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.

Standard Test Method for
Evaluation of Automotive Engine Oils in the Sequence IIIH,

Spark-Ignition Engine
This standard is issued under the fixed designation D8111; 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
Portions of this test method are written for use by laboratories that make use of ASTM Test
2
Monitoring Center (TMC) services (see Annex A1).
The TMC provides reference oils, and engineering and statistical services to laboratories that desire
to produce test results that are statistically similar to those produced by laboratories previously
calibrated by the TMC.
In general, the test purchaser decides if a calibrated test stand is to be used. Organizations such as
the American Chemistry Council require that a laboratory utilize the TMC services as part of their test
registration process. In addition, the American Petroleum Institute and the Gear Lubricant Review
Committee of the Lubricant Review Institute (SAE International) require that a laboratory use the
TMC services in seeking qualification of oils against their specifications.
The advantage of using the TMC services to calibrate test stands is that the test laboratory (and
hence the test purchaser) has an assurance that the test stand was operating at the proper level of test
severity. It should also be borne in mind that results obtained in a non-calibrated test stand may not
be the same as those obtained in a test stand participating in the ASTM TMC services process.
1. Scope Scope*
1.1 This test method covers an engine test procedure for evaluating automotive engine oils for certain high-temperature
performance characteristics, including oil thickening (as measured by kinematic viscosity increase), piston deposits, ring sticking,
oil consumption, and phosphorus retention. Such oils include both single-viscosity and multiviscosity grade oils that are used in
both spark-ignition, gasoline-fueled engines, as well as in diesel engines.
1.1.1 Additionally, with nonmandatory supplemental requirements, a Sequence IIIHA Test (Mini Rotary Viscometer and Cold
Cranking Simulator measurements), or a Sequence IIIHB Test (phosphorus retention measurement) can be conducted. These
supplemental test procedures are contained in Appendix X1 and Appendix X2, respectively.
NOTE 1—Companion test methods used to evaluate engine oil performance for specification requirements are discussed in SAE J304.
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:
1.2.1.1 Where there is no direct SI equivalent such as screw threads, national pipe threads/diameters, tubing sizes, and valve
sizes and springs.
1.2.1.2 The ring end gaps in Table A8.7, the dimensions for the blowby ventilation support bracket in Fig. A3.2, and the torque
wrenches in Table A8.1 are in inch-pound units.
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. Specific warning statements are provided in 6.11.6, 7.1, 7.2.1, and 7.3.

Until the next revision of this test method, the ASTM Test Monitoring Center will update changes in the test method by means of information letters. Information letters
may be obtained from the ASTM Test Monitoring Center, 6555 Penn Avenue, Pittsburgh, PA 15206-4489.15206-4489, Attention Administrator. This edition incorporates
revisions in all information letters through No. 17-5.
