API Service Symbol Logo

A design criterion for new categories is that the performance requirements of later categories exceed the performance requirements of all previous categories. Therefore, API SM oils will be superior in performance to SL, SJ, SH, etc.

The API Service Symbol indicates the API Service Categories, the API Viscosity Grade and the API Energy Conserving Category.

ILSAC Certification Mark Logo

The ILSAC Certification Mark indicates that the product manufacturer has been granted a license to use the "Starburst" symbol for engine oils which meet the latest Performance Standard of the International Lubricant Standardization and Approval Committee. ILSAC is a cooperative effort among members of The Alliance of Automobile Manufacturers (BMW, Daimler Chrysler, Fiat, Ford, General Motors, Isuzu, Mazda, Mitsubishi, Nissan, Toyota, Porsche, Volkswagen and Volvo) and the Japanese Automobile Manufacturers Association.

To qualify for the use of either one of these two symbols the supplier must conduct extensive engine tests to demonstrate performance of the product.
