Straight from the R32 service manual:
Transfer case (page CH-59) - 1.8 litres of Nissanmatic fluid D [approx. 1.8 litres]
Manual transmission (page CH-23) - Nissan gear oil MP-G special GL-4 #75-90 [approx 4.1 litres]
Front final drive (page CH-125) - Nissan gear oil hypoid GL-5 85W-90 [approx. 1.0 litre]
Rear final drive (page CH-125) - Nissan gear oil hypoid LSD GL-5 80W-90 [approx. 1.5 litres]
In other words, only genuine Nissan MaticD in the transfer case, anything GL-4 or GL-5 about 75W90 in the gearbox, any GL-5 gear oil in the front diff, any GL-5 LSD oil in the rear diff both diffs 80W-90 is fine.
Engine takes about 4.5l with filter. 10w40 is recommended.
With the driveline there is Castrol on the cheap or Motul/Redline if money isn't an issue. Engine Oil brand? just read the big oil sticky in this forum.
