Attached are my past two Oil Analysis' from Blackstone. Pertinent info:
2011 Bmw 335i [N55] bought used at 63,000mi.
Currently 85,000 mi.
Running Jb4, Map 1 constantly with occasional map 4 during super hot weather.
Running Pentosin 5w30 oil kits from FCP Euro.
Few pulls from a dead stop but alot of pulls from 2nd n 3rd gear.

First sample was after forum recommended 7,500mi. Blackstone advised to push oil change interval to 9,500 miles due to Super low wear metals and plenty of oil additives remaining.

Second Sample was at 9,500 miles. Again, super low wear metals and plenty of additives. Was advised to try 11,500 miles for next sample. I'll post results of sample at this 11,500mi interval in the future.

Btw, no magnetic drain plug or anything, and not running catch can... yet.
Overall, my engine is in great health and Pentosin Oil has been working out great. It's always good to have tangible insight into how your engine is working.
