From 1943, the US Army had qualified lubricants to its specifications, partly based on recommendations from an advisory body that it sponsored. Then in 1977, the US Army contracted SAE International to review and make recommendations on candidate products based on military performance specifications.

SAE created the Lubricant Review Institute, which established a Gear Lubricant  Review Committee.  This allows the US Army to retain responsibility for approving and qualifying products to its specifications. PRI has been involved in the Lubricant Review Institute since 1998, when SAE transferred the administrative function to us and a Qualified Product List was developed.
