Infineum developed an SAE 5W-30 prototype motorcycle oil using the components that during bench screening delivered the most engine friction credit. This prototype was optimised to achieve JASO SL quality and MA2, which is the highest clutch friction level in the JASO 2016 specification.
但不知該原型油品(prototype motorcycle oil)現在是否已有實際的成品在販售?
