Higher cold weights (5W or 10W as opposed to 0W) oils from a given manufacturer also tend to demonstrate higher film strength as well. That is also why they suggested the Motul product in a higher weight, which is a Group V oil with both higher ZDDP (1200-1300 ppm) and superior film strength when compared to M1.
