My car has been off the road and the track since I received the analysis on my M3 that showed high levels of copper in the oil. I’ve attached a picture of one of the bearings (actually two were “in the copper”) and truly believe that had I not gotten the early warning from my Oil Analysis the issue would have been much worse. I will continue to use Blackstone for the analysis, especially with fresh bearings in the car, to chart the health of my motor.
