Mobil 1 has a link showing Zinc, Phosphorous and Manufacturer approvals in a nice table, linked below. Interestingly, the 0w20 offerings in the various flavours, with two exceptions ( M1 EP HM 0w20 and M1 HM 0w20 ), have lower PP and ZN levels than the other grades, including 5w20's.
Wonder why ? Are they using something else in these 0w20's ?
And, the motorcycle and racing lines have much higher levels of both, with more than double the amounts in the racing oils.
