What model Jeep do you have and what does the Owners Manual say?

Does it actually have Limited Slip Diffs on it? If so and you use LSD Lubricant it does not need additives cos they're already in it.

it'll be Quadradrive II in the GC of that age and engine ..I wouldn't use anything else but Mopar spec oil and 4oz of modifiers in both front and rear .. there is a sophisticated clutch pack and solenoids in these diffs I would be very wary to go off Jeep spec

All the Manuals I've seen regarding lubricants, and not just for Jeeps, state Chrysler/Mopar/Ford or whatever, then add, OR lubricants which match or exceed this Specification, so if the specs match you're OK.

All models, all axles:

Mopar® SAE 75W-140 Synthetic (API-GL5)

 

Mopar p/n 04874469 (MSRP $33.50 per quart)

 

 

Electronic axle notes:

 

Electronic (ELSD) axles require 118 ml (4 ounces) of Limited Slip Additive be added to the lubricant. (Mopar additive p/n 04318060AB $10.50 MSRP 4 oz. bottle)

 

ELSD axles are standard with Quadra-Drive II.
