It supposedly does, if I recall correctly. Buried in that big oil thread I linked above I think there is some discussion of it.
They switched to 0-20 to overcome a cold weather starting issue. I encountered it once in Breckenridge on a below zero morning. It started and threw a code and said reduced power. I switched and haven’t looked back.OK!
AB does not have the 5w20 Castrol Professional (OE) in stock and they are saying it could be 3 months or more.
(Yes, apparently it is available on ebay, but at $80/qt that's not happening.)
SO....
Best Castrol alternative at this time?
Edge
Edge Extended Performance
Edge Euro Car
Keeping in mind that yes, we have all read the posts and likely commented on this before, and that I am not as liberal in my oil substitutions as some...
AND. My local dealership tells me that the specification for the 2013 has changed and they now sell and use 0-20 Castrol Edge Professional (OE) in the V8 - comments?

We use a lot of Motul at Robison Service. As for the commenter who notes the JLR spec will also meet ACEA A5/B5, that is true one way. In other words, the JLR rated oil can be used in any car that needs ACEA A5/B5, but you cannot assume another non JLR ACEA A5/B5 will br suitable in the JLR V8.
While many people believe/hope that any synthetic will be OK if changed every 7500 miles, why take the chance? The problem in these engines is that the oil is not strong enough to hold off metal on metal contact that produces wear. Do you think all that wear is happening at the 10k mile mark?
We have seen enough damaged engines to stick with the JLR rated oil AND ALSO strongly suggest a 7500 mile change interval.
