Gear Oil weight for ARB/44??

[lilgreenjeepyj]

Im looking to fill up my newly setup 44s both with ARBs. What weight should I run? Anything special for the ARBs? What about syntetic? I plan to run the cheap stuff to break the gears in, then switch to Syntetic.

Thanks

In your ARB Operating and Service manual it has all of the different oils for all of the different driving conditions and climates.

I'm using a 80-90 in my 44's.
