I have a 98 GU Patrol 4.2TD with Safari turbo and intercooler.
I am about to change the oil in both diffs to Redline synthetic as the current oil tends to cook on long beach runs.
Redline synthetic oil is quite expensive so I need to know how much to buy.
I have looked in the owners manual and on the Nissan website, and also googled for it, but I can't find any data.
Does anyone know what the oil capacity of the diffs is ?
Both diffs have ARB lockers.

Cheers

Try this link

This is from Caltex but most of the oil companies have something similar.

Front diff = 2.1 litres
Rear diff = 5.4 litres

Rear if no locker fitted requires LSD140 oil.
Hope this helps

I'm sure that's meant to be the other way around.

Be careful of redline - keep hearing good and really bad things about it. Might pay to stick to something like Mobil 1 synthetic diff oil

My mechanic uses Castrol oils, but I supply him with Shell Rimula X for my engine. I've don't like Castrol.
This is the first time I've changed oil types in the diff.
The current oil is absolutely useless so I obviously need something with higher pressure and temperature ratings.
I know quite a few guys in Perth who use Redline synthetic oils for all their lubricants and I haven't heard about any problems, quite the contrary. The University of WA uses Redline Oils for their race car project so they must have something going for them.

What problems have you heard about ?

Sorry, in one of my more un-specific moments, I have led you to believe that I had heard bad things about these oils....... this isn't the case, I was just curious to know if you had spoken to your mechanic about it.

"The current oil is absolutely useless so I obviously need something with higher pressure and temperature ratings"

Can you explain this to me with a little more detail? I am curious, and at this point in time , I don't know but am keen to learn.

Cheers

Brian

When I do long beach runs (10-15km's at 30-50kph) the diffs absolutely stink of burning oil. The smell is probably more noticeable because the diffs are vented above the level of the rocker cover.
I run in low range when on sand so the diffs are seeing more torque hence more pressure at the gear teeth.

My take on this is that the oil can't handle the temperatures and pressures generated by this activity.
I use the diff locks a lot on sand but it doesn't seem to reduce the smell, so this tends to make think it's a pressure problem at the gear teeth.

My solution is to use an oil which can take the pressure and temperature without breaking down - hence a fully synthetic oil.

G'day Fladylady,
I just did mine last weekend, 120 cruiser is nearly right, but wrong way round, 5 litres in front diff and 2litres in the rear.

You guys are right it is the other way around.
5.4 in the front
and 2.1 in the rear.

I have had a shocker with posts this week end. Too many parties and not enough sleep.

Thanks for the correction.

how many km's does your GU DX have on it and has it done 5th gear yet? Also at what km's did you turbo it?

Des,
Given that it's a 98 model, I don't think he needs to worry about 5th gear going. My understanding is that it only became a problem in the 2nd half of 1999 through until early 2001. Mine is a 2000 model and had to be done at around 80,000klm.

It goes in tomorrow for it's 225,000km service.

I haven't had any problems with my gearbox so far, and I've owned the vehicle for 4 years. I use it for club runs, sand, rocks, mud, etc, etc..

I assume the Turbo was fitted when the vehicle was new.
I bought the vehicle from ARB with lots of goodies on it :-)
