Got a link?And let us not forget the in depth research/trial article that someone here posted that showed that di moly was more effective than trinuclear moly at preventing wear. This is why Japanese oils prefer the older di moly in high quantities, their research showed it was better at reducing timing chain wear than the trinuclear variety.
Because the Infineum presentation (ironically, presented in Japan) showed trimer had lower friction and better synergy with ZDDP. With DLC's, dimer had a tendency to delaminate, which was not observed with trimer.
The "conclusions" slide from that presentation:
I suspect the reason many of the OE Japanese oils continued to use dimer was availability and cost. We really only see trimer used by Mobil and SOPUS, not surprising given it was originally exclusively an Infineum product.
