I finally got around to send in the UOA on this. A link to the interesting bits I found in my oil filter used for this OCI can be found HERE. Clift notes is that I found some material in the filter. The engine had been fed a constant diet of BMW LL01FE up to this point.
Tin (Bearings?) came in at 2ppm. Viscosity @ 100C came in at 10.8 vs 12.08 per PDS I presume if I kept going it would thicken up a little as I reached 10k miles. Going to do another UOA (LM 5w40) this summer (1 yr mark). I've only put 2k miles on the car since then.
