Outer Limits 4x4 Board

Hey all, I'm changing my oils and i'm wondering what grade is recomended for my 1991 LandCruiser's transfer. I have all my other oils sorted I just need some info in this.

Thanks

im running castrol vmx80 in gearbox and transfer makes the shift better when cold and most people swear by it. Looking on about 5 different forums the general consensus is the thinner the better

X2 only Castrol VMX-M is prefered over the VMX80, it is slightly different formulation and helps with notchy gear change in the cruiser gearbox
