What grade of Engine oil do people use for high mileage Tdci 2.4 Defender Pumas?

I do not think you will get a definitive answer on this, just what people do themselves. . The big factor here is the required Ford specifications, which are chosen by Ford for this particular engine. Our 2008 2.4 Puma has slightly less mileage than yours and I recently topped up the engine oil. It does not bother me that it needed topped up. The handbook says to check your oil level so Ford/JLR must expect it to use oil at sometime in it's lifetime.
There are additives in every engine oil and the additives in the Ford specification oil are different to those in another oil with different specification. The additives might be much the same but the concentration of each cocktail is tailor made to perform in certain ways specific to the engine. The 5W part of the oil was chosen so as to get lubrication quickly throughout the engine on start ups. I would not worry about top ups provided it is not an inordinate amount over short periods of time.
Maybe someone else will be along who has an engine that has 500.000 kms and never needed a top up. You can buy engine oil additives that you can add to your engine which are like treacle when being poured. These are advertised to work on worn engines and stop oil use. I would not use them as they are bound to have an effect on how the oil performs, especially on starting up. If it thickens the oil it will interfere with 5W part of the oil doing it's job.
I had a conversation with a sales rep who used to work for a major oil company about engine oil. If I get time I will put the jist of it up.
