The Japan Automobile Manufacturers Association, Inc. and representatives from Chrysler LLC, Ford Motor Company and General Motors Corporation, through an organization called the International Lubricants Standardization and Approval Committee (ILSAC), jointly developed and approved an ILSAC GF-5 minimum performance standard for engine oils for spark-ignited internal combustion engines.

 

This standard specifies the minimum performance requirements (both engine sequence and bench tests) and chemical and physical properties for engine oils for spark-ignited internal combustion engines. It is expected that many engine manufacturers will recommend ILSAC GF-5 oil. However, performance parameters other than those covered by the tests included or more stringent limits on those tests included in this standard may be required by individual original equipment manufacturers (OEMs).

 

Southwest Research Institute (SwRI) develops unique test cells and equipment to ensure fluids and components meet client and industry specifications.
