Transfer case doesn't determine additive, the prescense of a limited slip does.

Does the NP203[full-time] system use limited slip axles?
That's what I was wondering

Limited slips could have been ordered with full time or part time. The tranfer case dosn't determine open or limited slip diferentials. If you are changing the fluid you will be able to tell if it is open or limited slip by looking at it. If you are just topping it off I don't think a litle bit of strait 80/90 will hurt a limited slip. Limited slip additive wont hurt an open diferential either.
