My Unimog, 25600 mi OCI, about 700 hrs, sump 29.6L, 10L makeup oil (2.5l/6250mi since new)
Anchorage-Halifax-Antwerp-Ulaan Baatar-Germany-Venice-Antwerp-Halifax-Anchorage
Delvac 1 SHC 5W40
according to my calculations the makeup oil decreases contaminates by about 16% using the exponential mixing equation

Fe 44
Cr 1
Pb <1
Cu 9
Al 4

Si 5
Na 17
K <1
coolant none

Mg 36
Ca 4553
P 1387
Zn 1405
B 284

Water none

Vis 13.0
Fuel <1
Soot 0.4
TAN 2.84
TBN 11.5 even with about 8000mi of 300-3000ppm S diesel

Next time I'll try for 1200 hrs = ~45000mi

You drove a MB Unimog from Anchorage to Halifax, played around in Europe, then drove from Halifax back to Anchorage?!?!?

That's one helluva road trip!

Actually drove all the way to Mongolia and back summer 2016, left it in Germany at Unicat (camper mfg.) over the winter for some odds and ends,
But we went to Venice and shipped it back to Halifax and drove home this summer.

The Cu rose from 3ppm/17500mi to 9ppm/25600mi. Sn not at all. Does anyone think that means anything ? Leaching from the oil cooler?
