This is the second UOA I have done for the truck in my description. This sample was done on 5 quarts of 5w30 Mobil 5000 and one quart of MMO ran for 5,585 miles. The first UOA I sent in was flagged for high levels of copper. This second UOA below was flagged again for high copper levels. Im not very well familiar with reading these UOAs, is the level of copper in this sample really that high? If so, where could it be coming from? For the record, my driving is 80% city and the motor runs strong. It has never had an issue, its just enough to make my BITOG OCD go off!
