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.

FC

Ensures clean combustion and fewer deposits, suitable for motorcycles that require higher performance

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.

TC

The API TC specification is suitable for two-stroke engines (2T), ensuring good lubrication and protection of the engine from wear and overheating.
