thanks.

You'd have either check their websites for tech data sheets (assuming they have them which some do not), or visit a well stocked store and read the backs of some containers. Pay attention to the ACEA ratings rather than the API as ACEA requires the finished product to be tested in order to obtain ratings, while the API has shifted to a "self policing" and “component rating” mode since it became the public relations and marketing arm of the US industry rather than a watchdog............... You can find an ACEA "whitepaper" as a PDF file if you do a Google search, which will explain the meaning for their ratings system, which is very comprehensive.
