Using Castrol Edge EP 0w20 in the 5.0 S/C?

I've read that JLR has made some changes over the years in their oil specifications for the 5.0 engine.

Has anyone here switched to the 0w20 spec?

I don't think JLR are making any modifications for the L322 specs, but it seems that the AJ133 engine itself now uses the 0W20 weight in all the documentation since 2018.

Purely personal experience with no 'official' evidence; I used 0w20 on the change before my last and found it made things a bit noisier but no ill effects. Word on the web is that JLR changed it so that the oil can circulate quicker to chains / tensioners. I'm now back to original 5w20.
