Sounds ok.
Just make sure the rear diff oil is limslip variety.

Good to know. Just checked, and Penrite 80w-90 Diff oil does have Limslip added. Thanks Hodge.
On a somewhat related note - when I change diff oil should I be using some sort of sealant on the sump and fill plugs when I screw them back in? Changed both diff oils a few months ago and didn't use any sort of sealant and I have noticed that they have been weeping a bit of oil. If I should have used a sealant I would also appreciate some advice on what to use?? Thanks, Gags.
I've never used any sealant on sump and diff plugs.... Shouldn't need toQuote:

Thanks. Just went out and managed to get another quarter turn of tension - will see if that stops it from weeping!!
There is sometimes a copper washer that deforms to some extent to act as a seal. Apart from that, no sealer in threads
Further to this question .....
After speaking to my son "the mechanic", he says NOT to use any diff oil that has any form of "Limslip" added, as it could effect the workings of the factory fitted diff lock. He says that oils with "Limslip" additives should only be used in LSD's, not open or locker fitted diffs. I contacted Penrite who are making inquiries, as they were apparently unaware of this. They did contact ARB who also say not to use "Limslip" additives with their lockers.
To be continued ......
That is correct.
After checking out the diff oils at supercheap on-line, I found this listed, and purchased it. I'm hoping it's still available, as it's not listed in the Penrite web-site search. Supercheap says it's a special order from Penrite, so not kept in stores, and will be delivered.
Penrite HD Gear Oil Premium Mineral Non Limited Slip - 80W-90, 20l. ( only available in 20 & 105 lt drums and has no "slip" additives ) $160 for 20lts.
We'll see what happens.
just to add to big gags post . my car is almost due for its first gearbox and diff oil change so i've had a bit of a look around them and all of the filler and drain plugs have some sort of sealant around the plugs . in almost every other car i've had i've always had slight weeping from the plugs , very minimal , and only just noticeable, but there all the same. to make a tapered thread seal they have to be very tight and i have come across plugs ( hex heads ,allen key and slotted for flat head screwdrivers ) that have bee stripped because they were done up so tight to make them seal . they can be a real pain to remove . i have seen other alternatives to seal them as well . there is/was one system where you screw a plug in and then screw a cap in to the plug which seals with o' ring/s against the g/box housing to contain any weeping . years ago most 4x4,s would be parked outside on a patch of dirt and the odd drop of oil and grease here and there was part of the deal of owning a 4x4 . but these days a lot of people want to keep their car in the garage and not have it drop oil and grease on the floor , not to mention the issues this might cause with the authorities . i park my car in the garage , so would like what this sealant compound is that nissan has used .
Don't know if anyone is still following this thread?
Just to clarify. There is no LSD on factory 2014 GU Y61 DX cab chassis? I'm about to do my diff oils too, and i think it is just a standard diff lock? not LSD?
can someone confirm
If it's a dx and doesn't have an lsd it would be an open diff I assume. No lockers unless they were added and you would know about that. In this case it probably doesn't matter which oil you use. Limited slip stuff would do it.
I'd be interested to know also, picking up a 2012 model with locker in the rear, so assume that the oil will be the same front and rear. 80W-90 all round I assume? Still researching the options, but sounds like the Penrite is out. What alse is being used out there?
Cheers,
Paul

Looking through the treads it would seem that I can use the same oil in the gearbox and transfer as well, at least that would justify spending on 20lt.

looking thru the the manual it seems that a dexron lll atf oil is listed for the transfer box
Correct. If you use 80/90 the auto hubs will try to engage by themselves. If you use manual hubs or have converted your autos to manual. Then 80/90 is good.Quote:

Playing devils advocate, would the engineers not have taken that into account when they spec'd the 80W-90?
Is there a particular brand to recommend for the heavier oil, assume also that it would not want to have any limited slip additive.
pspeirs . a 2012 model may have a factory locker in it , it will be easy to work out which diff you have once you have the car , if it has a lock diff it will have a button on the console / dash to engage/ disengage the diff , and as far as oil is concerned is considered an open diff . you can get normal or heavy diff oil for LSD or open diff's at most places that sell car oils . the heavy oils( 90w- 140 ) is more for heavy towing or perhaps if you live in darwin or regularly push the car hard .
Yes, it does have a locker in the back, its this that made me confused as to whether it was a GU7 or 8. My days of pushing too hard are probably done, unless of course I leave the wife at home (and thats a very real option). The other thing I'm trying to consider is that the histort of the vehicle is unknown apart from the regular servicing.
