I have 2016 Nimso with 27K mi which I track and perform UOA after each oil change (typ. 3,000 to 5,000 mi). I know it's overkill; but that's what I do. I have 5 reports and trend chart the Cu and Fe contaminants, normalized by mileage (i.e. PPB/mi). I also switched from Amsoil to Motul 300V after the first two, where I noticed a big drop in Cu, although it also dropped from 42 to 23 between the first two reports.
The averages from the first two reports using Amsoil were:
Fe 13 ppm
Cu 33 ppm
Mb 45 ppm
The averages from the last three reports using Motul 300V were:
Fe 15 ppm
Cu 13 ppm
Mb 544 ppm
I would say your numbers look normal, but I would recommend you get a baseline with 3 reports, and then recheck as you wish to check for changes.
