Thanks

, I hope people are finding it useful.
Just watched that video.
For anyone who wants to watch that video, most of the 1st 2 mins is the guys showing off his car

(which is nice to be fair

), the bearings are shown at 2:17, they are quite worn but not terrible (for S65), typical for LCI bearings, although they have only done 31k miles. The oil analysis discussion starts at 3:25
Interesting video, but their are lots of mistakes he makes (which I commented there for anyone who cares).
