Land Rover LR3 transfer case fluid

Getting ready to change the transfer case fluid on the LR3. Can't remember last time it was done, at 239k now. I was reading this thread:

Hi all. Was wondering if anyone knows what oil can be used as a suitable substitute for this transfer box oil.

Google brings some oils up but they are still generally over £20 a litre.

Thanks in advance.

so it looks like DTF1 type fluid should be compatible, but it's full synthetic. The LR factory stuff is a synthetic blend. I'm leaning towards going factory since its worked this long, but curious what people here thought. I've also seen people have success with Royal Purple Synchomax.

DTF-1 is exceptional fluid. PAO and ester based. Ravenol DTF is also good.
But like you said, it worked so far.

Getting conflicting stuff now on if the LR stuff is synthetic blend. I think it's full synthetic, it's probably the same as any DTF1.

This seems to be the factory stuff. Ordered it. If anyone knows anything different, chime in! But from my research, the stuff above, or anything DTF+1, or Royal Purple Syncomax are interchangeable with factory.

Yep, that is BMW stuff. Though I do not know if it is the same fluid as the one in the BMW bottle. But people use that as they save like $20 per bottle.

Same exact stuff just rebranded for bmw. I have been using it for years.

For the price I wouldn't be looking further. I used Ravenol in our BMWs last time only because it was cheapest I could find a couple of years ago. It works great too.
