The JASO specifications were developed by the Japanese Society of Automotive Engineers for motorcycle lubricants. They define the performance and behavior of oils in wet clutches and two-stroke or four-stroke engines.

MA

The JASO MA specification is suitable for four-stroke motorcycles with a wet clutch. It protects the engine and ensures its proper operation.

The API specifications were developed by the American Petroleum Institute, which evaluates the quality and performance of lubricants in gasoline and diesel engines, according to international performance standards.

SL

The API SL specification provides reliable engine protection as well as clean combustion in previous generation gasoline engines.

SJ

The API SJ specification is suitable for gasoline engines produced before 2001. It protects engines from wear and deposits.

SH

The API SH specification is suitable for older gasoline engines (before 1996), providing basic protection and good lubrication.

SG

The API SG specification is suitable for older gasoline engines (before 1993), providing basic protection against wear and oxidation.

SM

The API SM is compatible with gasoline engines, offering good wear protection as well as high thermal stability. 

SN

The API SN specification is suitable for modern four-stroke gasoline engines. It offers high wear protection, reduces engine deposits, and ensures clean and efficient operation.
