The scope of this document is to outline the joint engine oil classification efforts of API, ASTM, and SAE. The designation, status, and descriptions of the categories are presented, as well as the test techniques and primary performance criteria.
The scope of this SAE Standard is to outline the joint engine oil classification efforts of API, ASTM, and SAE. The designation, status, and descriptions of the categories are presented, as well as the test techniques and primary performance criteria.
This SAE Standard outlines the engine oil performance categories and classifications developed through the efforts of the American Petroleum Institute (API), the American Society for Testing and Materials (ASTM), American Automobile Manufacturers Association (AAMA), the Engine Manufacturers Association (EMA), International Lubricant Standardization and Approval Committee (ILSAC), and SAE. The descriptions by API and ASTM, along with prescribed test methods and limits, are shown for active categories in Table 1 and obsolete categories in Table A1. Following Table A1 is a historical documentation of the obsolete categories. For purposes of this document, active categories are defined as those (a) for which the required test equipment and test support materials, including reference engine oils and reference fuels, are readily available, (b) for which ASTM or the test developer monitors precision for all tests, and (c) which are currently available for licensing by API EOLCS.
The purpose of this SAE Standard is to describe test conditions and performance evaluation factors for both diesel and gasoline engine tests. Specifically, the tests described in this document are used in the requirements for engine oils in U.S. military specifications, as well as in the API Engine Service Classification system described in API Publication 1509, and the ASTM D 4485, SAE J183, and SAE J1423 standards.
The purpose of this SAE Standard is to describe test conditions and performance evaluation factors for both diesel and gasoline engine tests. Specifically, the tests described in this document are used to measure the engine performance requirements for engine oils described by the API Service Categories described in API Publication 1509, ASTM D 4485, SAE J183 and SAE J1423 standards, and U.S. military specifications.
