Not sure what would cause copper to be that abnormal. Oil was in the car a year with <3000 (I think) miles on it since I bought not knowing the miles for the last service. Has an oil cooler which was mentioned in the comments. Some minerals were also high calc, mag, phosph, zinc. Test was done by Blackstone Laboratories.

A little more info on the engine, supercharged flex fuel 1300 injectors water/meth stage 1 block rods pistons retainers springs. I only have time frames when work/service was done.

"Copper is elevated in this sample from your Nismo. Universal averages show typical wear for the
Nissan VQ37VHR with about 5,100 miles on the oil. The other wear metals could stand to be lower than this
after a 3,000-mile oil change, but only copper looks outright excessive. It could be harmless if you've added
an oil cooler, from oxides, but it could also show excess wear at brass/bronze parts like valvetrain bushings.
Fuel dilution was okay at only a trace, and we didn't detect coolant or excess dirt in this sample of Red Line
0W/40. Check back on copper."

COPPER 58 average 7
ALUMINUM 6 " 7
IRON 15 " 7
LEAD 6 " 4
MOLYBDENUM 467 average 152
