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.
The conversion of the commercial item descriptions (CID) AA-52306 to SAE J2363 in November 1998 was done as an effort to align military needs with commercial manufacturers requirements and suppliers products. It is our belief that the API Engine Oil Licensing and Certification System (EOLCS), the American Chemistry Council (ACC) Petroleum Additives Product Approval Code of Practice provide a robust framework of requirements and oversight to allow the Department of Defense to purchase these products directly, with the understanding that only products with a formal API license and meeting the most current Heavy Duty Diesel Engine Oil requirements will be procured.
