Because it came with EGR, it has a factory centrifuge. MB says 1200 hrs for non-USA Unimogs, without EGR, with 228.5 oils; I think they do not have a centrifuge.
1200 hrs? More?
Sorry for the off topic.

Doug would probably be the best to hazard a guess, but i can add a couple of points.
Our fuel is
FWIW, our Nissan Patrol, which uses a 4.2 litre indirect injected TD with a factory by-pass filter and only a 10.5 litre sump could easily do 20,000km on CI-4 D1 towing horses.
The oil still had life in at that distance, but I was in front financially so dumped it.
At that stage our fuel was 50PPM sulphur.
