Depends on your preference, I use AMS oil 5w-30 in the motor. Redline heavyduty shockproof in the transmission and ams oil 85w-90 in the diff. The redline heavyduty shockproof is good in the summer, but it's like molassas in the winter and takes a while for it to warm up.

I use Mobil 1 10-30 right now, and i have valvoline 75w-90 in the transmission and castrol 80-90 int he diff.

Im about to switch to Royal Purple RTX 10w-40 and Redline Shockproof heavy duty in the transmission. Im not too worried about the Diff, castrol does a pretty good job with the gear oil.

In florida no cold problems, so 10w 30 royal purple or some people just run straight 30 or 50 w down here. In the welded diff the cheapest I can find, and in the transmission royal purple also. And in the skyline diff r33 I can't find a fluid that I like. I thinks its because the writing on the can is in Engrish. I need one that has characters not letters...
