I'm not convinced that there is no other oil for the l322 transfer box than the original from Castrol BOT only supplied by Lan Rover.
What is your sugestions?

I use Ravenol TF0870.

An other option : https://www.advancedfactors.co.uk/adv903-i...0908-p.asp TDV8 4.4 2012

There's quite a few choices to search:

Smith and Allan (popular company with forum members)
Ravenol
Westway
Rock Oil
Febi Bilstein
Mannol 2015 Range Rover Autobiography 4.4 SDV8

Loads of options as above. Ensure it meets the spec as per WM or Handbook and you'll be fine  Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
2025MY Defender D350 90 in Silicon Silver on coils
1974 Series 3 Lightweight = "Millie"
Many, many other Landies over the years

The oil recommendations suggested above do not apply to the NV225 transfer case found on the 2002 to 2006 TD6. TF0870 should not be used.

Ravenol do list LS SAE 75W-90 as suitable but I have no experience with it. I hope RRPhil will see this thread and provide further guidance.
