I just got back my latest UOA for Motul 5W-40 and noticed an interesting change. It looks like molybdenum, calcium and boron have increased and zinc and phosphorus have decreased based on the past trends. I've been running the same Motul 5W-40 since 128K mile, so this should not be a leftover remnant from some previous oil. Wear rates still look good so not really a concern, although I typically like to see higher zinc and phosphorus numbers. Not sure if anyone else is seeing the same trend.
