If I correctly understand what it is, they DO use it, just likely in lower concentrations than an additive bottle would provide.
Yep, they have been using MODTC for years...go back in time, and there was much debate on BITOG about Delo400 having Moly while the diesel engine manufacturers were against it (they were against MoS2).
Nulon have used MoTDC as advertising on their bottles for 5 years or so, like they just invented the stuff.

There are a number of forms of soluble moly such as X-nuclear moly, MoDTC, MoDTP.
The culprit in diesel engines was MoDTP or moly dithiophosphate.
There was an industry paper about 2002,3 that showed while MoDTP was great in hydraulic oil, it caused corrosion problems in diesel engines due to their higher combustion temperature.
Once again, soluble moly's are only one form of friction modifier.
I have never seen any advantages to PTFE in any motor oils. It does make a good grease thickener for certain applicatons.
