Assuming you did enough changes to flush the residuals at what point would you start seeing a normalizing of metals within the oil? 10,000, 15,000, 20,000 mi?

Gene, my truck showed high iron for the first 25,000 miles after a new short block was put in my Ram listed below. That seemed a bit long for me but it is what the Blackstone samples showed. The truck is used as a daily drive and to pull our 36' travel trailer.
