JASO is the Japanese Standards Organization, it represents el key players in the Japanese Automotive sector. The JASO standards have been broadly adopted by oil marketers and Original Equipment Manufacturers globally. The T903 specification is specifically for four-stroke motorcycle engine oils. It specifies a performance framework and specification for both wet clutch gear transmission motorcycles and CVT scooter aplicaciones.

The T903 specification consists of three parts: the engine rendimiento, el clutch friction Rendimiento, y thirdly physical chemical limits.

On the 8th of May, JASO released their latest update el T903:2023 version. The required crankcase performance has been aligned with the latest API which is the American Petroleum Institute specification. The SAE number two has been updated to use the latest friction materials and reference oils. The physical chemical limits have been changed for improved protection of the three-way exhaust catalyst.

Lubrizol anticipated these changes our current Technologies are already T903:2023 capable and ready to go.

Going forward, the use of dedicated motorcycle oil formulations will be increasingly required to meet the needs of modern low emission high power density hardware.
