ILSAC

ILSAC stands for International Lubricants Standardization and Approval Committee. ILSAC was formed through the cooperation of JASO (Japanese Automobile Standards Orgnization) and the AAMA (American Automobile Manufacturers Association) as a result of their concern regarding the slow response of the SAE, ASTM and API in updating lubricant performance specs to match the rapidly changing lubrication needs of the automotive industry.

ILSAC is now the governing body which has been empowered with the task of establishing minimum performance standards for the lubricants used in todays gas engine passenger cars and light duty trucks. However, the SAE, ASTM and API were not pushed entirely out of the lubricants classification and certification process. Instead, ILSAC joined together with those three organizations to develop the EOLCS (Engine Oil Licensing and Certification System).

The EOLCS is simply the mechanism by which oils that meet ILSACs performance requirements are licensed, and the API is the governing body which has been assigned the task of administering the EOLCS certification process.
