Problem with most responses here are oils of the past with API CI4 plus and CJ4 oils that had plenty of Zinc and Phosphorous anti wear additives. With the implementation of the current oil API CK4 Chevron (Delo) and ExxonMobil (Delvac) chose to reduce Zinc and Phosphorous levels in order to be in line with the gas engine API SN specification. Having said that I would avoid these two brands for now.
