Whatever you do with this engine the new oil will be pitch black within five
minutes of a change.
If you are really fussy and the oil has been in the engine that bit too
long, add a quart of diesel to your oil and run at idle for a minute or two
before draining. This will thin the old oil so it drains better. Very
occasionaly, and if another diesel vehicle happens to need changing at about
the same time, I drain both and refil the Landrover with the used oil from
the other vehicle which will have oil that is relitively much cleaner. I'll
run it on this for maybe five miles before draining again and refilling with
fresh oil and changing the filter.
After this the new oil will appear resonably clean for an extra ten minutes

Let it be. These engines seeped oil from new. Not badly. Certainly not worth
bothering with. If it doesn't leave a pool under the car or cause a bother
passing MOT, leave well alone. It's a Land Rover not a Lexus.
