.......Reason I ask is that I asked on here before and was told not to as it messes with the car monitoring the oil quality.
Are you sure it does this ?
If it does I'd like to know how....BREXIT - done properly.

How do you expect your car to ask for oil?
When you follow the procedure of checking the oil, if it needs some, it says "Add 0.5l" or similar. There is a procedure in the handbook which then tells you how to add it.
If it says ok, you don't need to add any is my understanding?

It tells you how much to add and then incorporates the new sensed level into the oil quality algorithm. If the vehicle has a number of aborted DPF cycles and the oil level rises beyond that acceptable (due to diesel contamination) then the vehicle will display the oil service caption.
As discussed elsewhere on the forum there is a concern that the algorithm allows too much oil contamination as it seems rather too relaxed about a rise in oil level.Land Rover - Turning Drivers into Mechanics Since 1948
I checked my level this morning on the IID and the car. IID says 4.5L, the car display shows halfway between min and max, but doesn't state how much should be added. Think I will buy a litre today and add half and see what difference that makes. I though there was a litre between min and max on the display but the IID tool volume doesn't support this..

hmm, but when I check with the IID, the volume is not always the same within the space of minutes - so how do I get an accurate reading???
After my commute to work of 8km, I see 5.5L on one day, and 6.3L the next day, so which reading do I trust? --

Like for like (same temperature and sufficient time to flow back to the sump) the results should be the same - mine are.Land Rover - Turning Drivers into Mechanics Since 1948

When you check the oil using the correct procedure, does the car ask for oil or say ok? If ok, see robbies post above.
If it needs some, it will say add "0.5" or whatever

Car doesn't ask for any oil. Just rechecked and level is on the first notch above halfway. IID now saying 4.9L with a level of 127m (though I believe this to be mm). I don't have a DPF so not as concerned about the level rising due to contamination.
is 5.5L enough? or should I top up until it reads 6.5?--

I would go by what the car display says after ensuring the oil was cold and sufficient time given for all to drain back to sump after switching off. and add half a litre max at a time until you can see the effect on the display.
