Might take the GU for a spin up to Agnew next week if all goes according to plan, so I'm giving it a bit of a birthday while I've got some time on my hands.
My question is, from practical experience, what are the best oils to do the diffs, gearbox and transfer case in a '99 GU Patrol ST 4500 petrol? I want to stick with readily available brands, preferably Castrol as it can be bought anywhere at a reasonable price. Vehicle has done 178,000km's.
I've searched the archives extensively but it all got a bit much to take in.
So what do you folks recommend in Castrol only, using no additives and no $90/500ml synthetics please. Should I just stick to the standard generic listings or use something else.
While I'm at it, what is the best coolant?
Cheers.

I have been using the following since new, almost 200000kms now and not a problem.
Front Diff: Castrol EPX 80W90 (recommended in the Castrol book)
Gearbox: VMX 75W 85 (if my memory serves me right, also from the castrol book)
Transfer Case: Dextron III (also from the Castrol book)
Rear Diff: LSX 80W 140 (also from the castrol book)
Castrol coolant but not the one they sell at supercheap already mixed, I buy it in concentrate from the depot.
***IMPORTANT*** make sure you don't mix, specially the coolant, drain flush and then fill, use demineralised water to mix with the coolant if you have any doubts about the water quality
All Castrol oils mineral at a reasonable price but I do change them "all" every 40000kms regardless.

I take it the Nissan doesn't transfer oil from the gearbox oil to the tranny case. . . . if it does, how do the oils go mixing?? I was always told never to mix different oil types. (I know that boxes shouldn't transfer oil, but they do no matter who make it!)

Impossible in this one, the gearbox is separate from the transfer case, it looks like they are together but there is a big spacer in between so if either one was to leak, the oil would end up on that spacer and drain to the floor I know what you mean, it was common in the Landcruisers and they even used to add a hose so it would equalise back.
