Recently, it seems to me that a lot of formulations are moving away from ZDDP and going for more hBN and Mo to make up for less Zn/P.
Is this shift in the AW chemistry effective long-term?
I'm not saying that these AW additives are not studied or tested otherwise we wouldn't have seen them in finished products, still no one talks about them. I'm asking if it's possible that hBN is the lesser of two evils rather than relying on reduced Zn/P alone, and formulators knows this, yet they have no other choice.
