Hi, I just got my 1st report after rod bearing replaced with BE bearing and OEM bolts at 70210 mileage. I hope can get some thoughts from expert here. I very confuse with the lead and copper ppm reading. Doesn't it at least 1 or 2ppm lead make sense? Why the copper ppm reading higher than lead? Any inputs I'm very appreciated. Thanks for advance. Attached is the Redline 5w50 last summer.
