American Automobile Manuf. Assoc.

AAMA is an organization of North American automobile manufacturers which has a great deal of influence over the lubricant minimum performance standards as set forth by ILSAC, SAE, ASTM and the API. It was the AAMA along with JASO that helped to create ILSAC (International Lubricant Standardization and Approval Committee) which plays an integral role in setting the minimum performance standards for motor oils and lubricants.

Since ILSAC has its roots in a cooperative arrangement between JASO and the AAMA, it's role is very much influenced by what the AAMA wants. So, the AAMA plays a role in the standardization of lubricants testing and performance criteria.
