Thread: gearbox,diff,transfer oil

I use a 50-50 mix of 80-90 and 85-140 Nulon on diffs and transfer.
I found that towing in hot conditions made the transfer case oil go discoloured quickly.

When I changed to the mix the oil stayed a good colour.

It makes it hard to change from hi to lo when cold but other than that is fine.
I cannot comment on the gearbox other than to repeat what others say that Castrol Syntrans is the go.

This refers to a D1 or D2 or an old RRC with LT230 as you don't say what type of car you have and it is not in your profile.

Well if you have read all thats in there about oils Im afraid what ever further we say you may more than likely will fail to understand or grasp either

It's not a matter of failing to understand or comprehend the information but no real information on the oils in question unfortunately schuy1 you have failed to grasp the question at hand and instead have a febil attempt at my intellectual integrity. I thought my question was fairly straight forward regarding theses two nulon oils I apologize if this confused you schuy1.

You might find some information here.

feeble? Sorry, couldn't resist it.
BTW I use Nulon 75-90 semi synthetic in the R380 and LT230, and I'll put this in the diffs when the time comes.

I used Castrol VMX 80w in the gearbox and Castrol 80-90 in diffs/tc on D1. The D2 is auto, but still uses the 80-90 in diffs/tc.

gulf western do a very nice sae90 for diffs and transfer cases etc

$99 for 20l at supercheap i believe

use it all thru my fleet with a touch of CEM AW0

syntrans for any manual landrover gearbox is my preference

i personally wouldn't put nulon on a wheelbarrow wheel after my experience with it in gearboxes and overdrives

to each his own though...

Thanks all who gave me constructive advise much appreciated would be interested as to the trouble you had incision with the nylon product I had my gearbox oil changed son time ago by a land rover specialist he used syntrans in my gearbox found it a pita from 1st to 2nd when cold. I have found nulon engine oil to be fairly good but it is changed every 5000k without fail other oils not so often.
