Thread: Transfer box and diff oils

You can get a Ravenol substitute for the transfer case from Europe. From memory it's about 8 pounds per litre or $50 from Rovacraft.

I just did mine. Seriously easy job.

Yeah, serves me right for typing without checking...

Nulon 75w-90 Performance smooth shift full synthetic in transfer case
Royal Purple Synchromax in diffs

RP imported based on availability and price, hate being gouged.

Through research I have found that you can use Nulon syntrans in both ZF6 transmission and transfer case . I have travelled with Nulon syntrans in my transmission for over 20,000klms with no problems as well as the transfer case . Gave the D3 a workout in the flinders rangers in September with not a problem. For the Ediff I used a GM carbon modified oil that is used in their lsd diffs at less than half the price of the land rover equivalent with the same specs

Any links to the Nulon syntrans specs you researched.

The transfer case oil is much lighter than 80/90. It's actually very similar to ATF in its viscosity. It also smells a lot like LG6 although I think it may be slightly thicker. For the sake of $100 every 80-100K km I would just use the Shell/LR/Ravenol oil.

That's good to know as I'm soon to change mine for the first time. I just changed the front diff oil - another seriously easy job using the spout on the 1L Syntrax LL bottle.

I read an article on the UK Forum where a guy ordered the transfer case oil for the D3 when it arrived on one side had all the specs for the transfer case oil, when he looked at the back label it said lifeguard 6

I've read the same thing. It does look and smell the same as LG6. I'm not able to find any specs on either so it's impossible to tell if they are the same without having them both analysed.

To my admittedly untrained eye, the transfer case fluid seemed thicker. Definitely nowhere near as thick as 80/90 though. I have a viscosity measuring funnel but I didn't test them.

Graeme, TFC is way easier than the diffs! Just put the car in offroad height and you can get easy access to it while on a creeper.
