Rear Locking differential

Good evening, I have a 2012 6.7 with a rear locking differential. I going to be changing oil in it and I will probably be using Mobil syn 75W-140. My question is do I need to any additives with a locking differential? I did own an explorer that had an LSD that required Ford LSD fluid.

No additive needed for the locker equipped rear axles.

Yep, friction modifier only needed for a limited slip type.
