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.
The conversion of the commercial item descriptions (CID) AA-52309 to SAE J2362 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, and the International Lubricant Standardization and Approval Committee (ILSAC) 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 ILSAC requirements will be procured.
