Turk:

As I said, the MoS2 oils have not been proven to help in the normal running of an engine. Yes, since it's particulate a good oil filter will trap the MoS2, leading to the filter bypass opening. This gives a drop in oil pressure all by itself, and of course the filter does nothing after it clogs up.

I will not use it for anything except break-in lube on a new cam in a piston engine. And even then, not on a roller cam.

Really don't thnk the moly would have helped keep your VW rrunning - if it was run out in 35K miles there was definitely something wrong. Most likely somebody ran the pooh out of it.
