Diff Oil & Transfer Box Oil 300

Looking to do the diffs and transfer box next weekend on my 110 1996 300tdi. I've read a few posts on here it will use about 5L of EP90 but then I have seen conflicting posts. I might be confusing myself here but thought I'd ask instead of messing up.

Looking to pick this up in the week, would this be ok for both?

I know it's been answered a few times think I'm just reading into it to much.

Thanks again
