This has been extensively discussed in this forum in the past as well as in the other concurrent thread about this topic (ps, this thread is the dupe).
It's simple. What's best for our engine is to get rid of all the nasty stuff the EPA forced the engineers to do to it. So: turn off EGR, get rid of PCV, and cut off the DPF. The SCR basically does nothing useful for the owner except make the garage smell like cat urine, so delete that too if only to improve reliability.
Makes sense, right?
The MS-11106 oil spec was a deliberate decision to sacrifice engine protection to preserve long-term DPF function (and possibly to slightly improve the fleet CAFE number towards the target demanded by the EPA). Everyone knew all along this was worse for the engine compared to something like Rotella T6. Thank the EPA.
Daily reminder that the "cheating" VW engineers were the good guys.
