I saw that and have used RM European for years with great results. I just wasn't sure what to think about the fluid.
So, for the purpose of this thread, there appears to be three types of fluid that at least some vendors identify as Land Rover part number LRN1375:
Febi Bilstein, ~$10/liter, such as:
http://www.rmeuropean.com/Products/LRN13754-MFG36.aspx
ZF LifeGuard: ~$21/liter, such as:
http://www.roverparts.com/nxt/?keywords=LRN13754
Land Rover labelled: ~$31/liter, such as:
http://www.ebay.com/itm/262816635036 (I've seen it mentioned that the retail price on this is $57/liter but have no link)
The factory service manual specifies Shell M1375.4 as shown in post 10 in this thread (
http://www.landroverworld.org/posts/172619/). This is an oil spec and from what I can tell Shell themselves do not market an oil meeting that spec, .
Clearly Land Rover doesn't have an oil refinery in Germany, so someone else makes it for them. The question is if the Febi Bilstein or ZF is the exact same formulation. The Febi says it's made in Germany too, and ZF makes the transmission, but then neither of them claim that their fluid is what LR specifies other than meeting the spec and none of the suppliers who are claiming that these are equivalent will be on the hook if your tranny gives out. Then there are other cheaper brands that also say they meet the Shell M1375.4 spec. So, who knows. The only safe bet would be to buy the LR labelled stuff. From there it's up to your tolerance for risk, I guess.
