This SAE Standard defines the limits for a classification of engine lubricating oils in rheological terms only. Other oil characteristics are not considered or included.

The purpose of this SAE Information Report 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 D4485, SAE J183, and SAE J1423 standards, U.S. military specifications, and ILSAC GF Standards.

This SAE Recommended Practice was developed cooperatively by SAE, ASTM, and API to define and identify energy conserving or resource conserving engine oils for passenger cars, vans, sport utility vehicles, and light-duty (3856 kg [8500 pounds] GVW or less) trucks.

This SAE Standard defines the limits for a classification of engine lubricating oils in rheological terms only. Other oil characteristics are not considered or included.

This SAE Standard outlines the engine oil performance categories and classifications developed through the efforts of the Alliance of Automobile Manufacturers (Alliance), American Petroleum Institute (API), the American Society for Testing and Materials (ASTM), the Engine Manufacturers Association (EMA), the International Lubricant Specification Advisory Committee (ILSAC), and SAE. The verbal 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. Appendix A is thus a historical documentation of the obsolete categories.

This SAE Recommended Practice is intended for use by engine manufacturers in determining the Fluidity/Miscibility Grades to be recommended for use in their engines, and by oil marketers in formulating and labeling their products.

The information in this SAE Recommended Practice has been compiled by Technical Committee 1 (Engine Lubrication) of the SAE Fuels and Lubricants Division. The intent is to provide those concerned with the design and maintenance of two-stroke-cycle engines with a better understanding of the properties of two-stroke-cycle lubricants. Reference is also made to test procedures which may be used to measure the chemical and physical characteristics of these lubricants.

This SAE Standard outlines the engine oil performance categories and classifications developed through the efforts of the Alliance of Automobile Manufacturers (Alliance), American Petroleum Institute (API), the American Society for Testing and Materials (ASTM), the Engine Manufacturers Association (EMA), International Lubricant Standardization and Approval Committee (ILSAC) and SAE. The verbal 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. Appendix A 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.

This SAE Information Report lists engine and laboratory tests for service fill engine oils which are associated with specifications and classifications established outside of North America. These specifications and classifications include those developed prior to June 1, 2006 by International Technical Societies as well as individual original equipment manufacturers. The information contained within this report applies to engine oils utilized in gasoline and diesel powered automotive vehicles.

This SAE Standard describes lubricating oils meeting the physical, chemical and performance requirements of American Petroleum Institute (API) performance categories CF and CF-2, CI-4, supplement CI-4 PLUS, and SAE J300. These oils are suitable for the lubrication of wheeled vehicles with compression-ignition (diesel) engines. This document supersedes the military’s Commercial Item Description (CID) A-A-52306.

This SAE Standard describes lubricating oils meeting the physical, chemical, and performance requirements of the American Petroluem Institute (API) SM category and the International Lubricant Standardization and Approval Committee (ILSAC) GF-4 standard. These oils are suitable for the lubrication of spark-ignition engines (gasoline engines). This document supersedes the military’s Commercial Item Description (CID) A-A-52039.
