How much limited slip additive?

Well my rear diff cover has been leaking for a while so today im finally getting around to pulling the cover off so i can re seal it. Im going to replace the stock cover with the 08 finned one while im at it.


I just ran out and picked up 4 quarts of syn gear oil and a 4 oz bottle of LS additive from ford. The bottle doesnt say anything about how much to add. Do i just put the whole bottle in there? Thanks

- Plus 8 oz. (U.S. measure) additive friction modifier, C8AZ-19B546-A (EST-M2C118-A) or equivalent for limited-slip applications.

Hmm so that would mean i need 2 bottles of this stuff right? Stupid ford guy asked me how much i needed and i said i dont know, enough for 1 sterling 10.25 axle and he said he THINKS they usually just put in 1 whole bottle. The bottle i got is like 3.98 oz.
