I need to know if anyone knows what can cause an oil test to come back with high copper. The amount was 46ppm. The car only had 5k miles on it and the oil that was tested came from the second oil change at 4100 miles. In other words the oil only had about 900 miles on it.
The oil was suppose to have been the 5w30 ester. It was not. The dealership put in 5w30 Synthetic. The test also showed it had a viscosity of only 20.
