Motul 300V 5w40, I always change oil after 6 track days. Not concerned with iron or copper levels. Compared to the last 3 reports from my 2017 BRZ, Motul 300V 5w30, engine rebuilt to OEM specs:
cumulative miles: 2450, 4266, 6106
iron: 8, 12, 7
copper: 5, 4, 2
Iron seems to be ok, copper a bit high but it has been trending down.
