Is that the oil weight they call for?

Molybdenum levels can also be from wear on piston rings. The upper piston ring may have a moly coating.
Are you getting enough upper cylinder lubrication with a lighter weight oil?

Looks good for right at 10k, XOM now guaranteed regular M1 to 10k, and with 3 left for TBN you are comfortably in that, and still in grade.

Yeah … not much written here when a 20 turns in numbers like that … until that truck takes on a harder life … nothing in need of change as is … Nice run !
I pull a 26’ Imagine 2600 travel trailer about 10% of the interval

What is the native silicon on M1 AFE? 24 looks just a touch high but I don't see any signs of any abrasives in the oil. Normally I would expect higher iron, aluminum and chromium numbers if that was the case. If maybe a 1/3 of that came from the oil it would be about what I would expect.

In my experience with 4 Tundras, Silicon stays relatively high until after the 30K miles mark. This oil started service around the 20K miles mark, so it's right on schedule...It's due to the sealers used internally
