OK, are the factory filled M1 cars ( Vettes, Porsche, etc..) getting M1 cuz it's the best for the car/engine, OR because it's driven by big business. Say I give you the rights to factory fill my WonderCar in return for mucho $$$. Which you turn around and say "We factory fill Eds WonderCar so we are the best oil" Everyone makes out well from the arrangement. But other oils may do just as well. Thoughts.....?
