Rear End Oil Limited Slip

[Troy911]

I have a 1992 325i with a 5 speed and a limited slip Diff , can someone tell me the right kind of Gear oil I need for both . Thanks !

I use Redline products. Trans I use Redline MTL and Limited slip diff I use 75x90 Redline oil. There is also shock proof oil which locks up the limited slip sooner but it is noisy.

Use any name brand synthetic 75w-90 with limited slip modifiers. I use Royal Purple Max Gear.
