This is from 2007. Truck is a 2006 Toyota Tacoma 4.0
No makeup oil was added during the run. Mobil 1 oil filter and OEM air filter. Driving was mixed stop and go with some long freeway runs in between. 7,350 miles when sampled. Interested to take another sample now that I am at 67,000. Have performed several OCI's since but with no UOA's. Copper stands out. Unsure of the culprit beyond RL chemistry.
