Gday Paul, have a try of the search function(top right of the screen). There are a few threads mentioning diff oils. Make sure the rear diff has LSD compatible oil.

Tap, crackle, pop

I used penrite 80w-90 up front and penrite limslip 85w-140 in the rear on my GQ, you can use the limslip 80w-90 in the rear..... I just chose the thicker grade as I thought it might be better for me old clunker

Yeah I find the 85-140lsx helps the rear work a little better and as stated above just a 80-90 gear oil in the front.

"You should find".
Penrite list straight 140w lsd oil.

if you use 80-90 LSD in the rear diff it will shudder [when taking off and turning at the lights for instance]
found out straight after a service and when i checked i found they had used 80-90 LSD
took it back, they changed it to 85-140 LSD and no more shudder.
