Wear metals look excellent for that long of a run. Would like to see a TBN analysis at this mileage, I would guess it would be very low. My TBN for M10W40 was less than 50% of starting TBN at 8500 miles.
Flashpoint and viscosity are low. Suggest doing a TBN on next run to see how additives are doing. 10k OCI is a good idea IMO.
Also suggest posting this on the used oil analysis section of
