I do not know about the LR4 specs, but my LR3 is at 145,000 miles and so far it has had 8 oil changes in its liftetime. I am the 3rd owner since 96k, but records provided show 14k, 33k, 52k, 73k, 96k, 107k, 119k, and 139k. 14k, 33k, and 96k were with dino oil as that was the spec in 08 and that is what the dealer uses in those cases. The rest were Mobil 1 full synthetic 5W30. I am not aware of any issues related to the oil changes. The previous owner claimed he had a good friend in the oil business who said the modern synthetics would all easily do 20k+ anymore, but that making that claim would hurt sales, so they dont.
I just change the oil every time I am in a shop. For my old DII, that was every few months! The LR3 and RR once or twice a year depending on how lucky we are with problems that year. The RR only goes about 7500 miles a year anyway, so it is not a major issue. Our Saab which gets used under 2k per year I change every year regardless. Now if I had the LR4 I would likely do it more often with a Mityvac just because I could. Time, space, and conveninece are limiting factors with the vehicles we have.
There is just too much mixed info on the topic for me to buy into any one theory and I do not have the time or desire to study motor oils to the point where I am satisfied with my knowledge of them. I would end up like GSXR with lots of facts, but still no clear answer. It's less frustrating this way
