D4 Transfer & Diff Oil Question

[John_D4]

Can I use this oil in the transfer case and diffs of my 2013 D4?https://uploads.tapatalk-cdn.com/20191111/9467c2fed64715f1aa7016d00018b852.jpg

I could only find a spec sheet in Russian (at least that's what it looks like) for that oil. From what I can gather looks like a manual transmission oil - GL-4. I wouldn't run it in diffs or the transfer case

Ditto.

One of the Russian TDS said it's a GL-4, i definitely wouldn't use it in a diff.

Tfr case oil and diff oils are completely different - use genuine LR oil in the tfr case. I use this in my diffs and works well

This oil came from the Holden factory when it closed down (bought legally). No probs, I’ll get rid of it and will use other oil.

Why genuine oil over Penrite for the transfer case?

As far as Im aware penrite dosent have anything that meets the spec for the transfer case. I use royal purple syncromax in my D3 as that is claimed to be compatible with the required spec

Why genuine oil over Penrite for the transfer case?

Because the tfr case is pretty unique and I don't believe Penrite make anything compatible. Remember the tfr case is nothing like a simple gear tfr case like the LT230 - There are other compatible oils from other companies but most cost about the same as the genuine LR oil.

Roger, Penrite pro gear for the diffs and LR oil for the transfer case.

I don’t have a workshop manual yet, how much oil for the diffs and the TC?

[101RRS]

· Replace rear diff oil – 1.1 litres of Castrol SAF-XO - 75W/90 spec grade oil
· Replace front diff oil – .61 litres of Castrol SAF-XO - 75W/90 spec grade oil (non e-diff)

· Replace transfer case oil – 1.5 litres of Shell TF 0753 spec grade oil

If you do not want to us the LR oil in the transfer case then the Royal Purple Synchromax is a good alternative - LR oil is about $80 a litre while the price of the Royal Purple varies around $50-$60.

Nice. 2lt of each. Thanks for your help

Also - I should have mentioned - the book says to put in those amounts - however in my experience it is close enough to just fill to the bottom of the fill holes as long as the vehicle is level. Everytime I have done mine (the tfr case every 80,000km) and the diffs every 24,000km it has worked out to be only a few mls in it - slightly over.

So just below the point where it runs out? Excellent. Thanks again Garry

[101RRS]

Just fill till it runs out then put the filler plug in and clean up. If you have a rear e-diff you will need to lookup oil and capacity as it is different to a normal rear diff.

Yep - like 101RRS said - the transfer case has an electronically controlled multi-plate wet clutch in it to provide centre diff locking and torque biasing function (for control of off road performance and on road comfort for example when parking). The LR specific oil (and the Royal Purple alternative) would be specified with the wet clutch in mind.
