Many HDEO have 0 moly and yet they have excellent uoas. Usually, like Quattro Pete said, there are other AW that acts similarly.
People seems to focus a lot on moly content, but an oil formulation has to be looked at as a whole and not focus on one of the many ingredients.
That being said, some researches came to conclusion that moly might help timing chain wear, but so does boron.
Exactly! This reminds me of all the threads that obsess over base oils, that one oil is better than another simply because of the base oil content. Ha. Each oil producer additive packages have many different chemical substances in different quantities, with the goal being a complete package (antiwear, low volatility, resistance to oxidation and shear and other breakdown, all that stuff). Zero moly means nothing because the performance of the finished lubricant product is what matters. Thank you jbutch.
