Tell that to Ford Motor Company. I'll stick with what Ford tells me to use, API Certified. I chose certifications, not snake oil.You don't have to worry. Amsoil has always been way ahead of the API. Way ahead.
Generally speaking, API is a industry self imposed label. It's like letting the fox regulate the hen house.
