This truck is used as a plow truck and had a high number of idle hours during this OCI. It also had 3 injectors replaced and they didn't change the oil after they did the work. This batch of oil contained 4 qts. Schaffers 9000 5w-40, 5 qts Schaffers 7000 15w-40, 1 qt Schaffers #132 EP Moly Additive, M1-303 oil filter. Blackstone Labs seem to think that the injector work may have caused the high levels of copper. Is there anything else that could possibly lead to the level of copper as shown in the report? BTW, the truck had 56,206 miles on it and the OCI was 6,507 miles. The total hours on this sample was approx. 275 hours. The lab report is listed below:
