Yes= always. And a direct quote from Lloyd Butfoy on the subject is, 'Using 
'Posi-Lube' (traction additive) in your ZF won't hurt, and may help". 
Nowadays in the U.S, most differential lube says "For Posi-type differentials", 
which covers the ZF LSD and is handy: no extra additive needed. Note the 
additive has nothing to do with the quality of shifting, only the working of the 
limited slip clutches. FWIW, many synthetics will leak from older design 
transmissions since their seals & gaskets weren't made to cope with synthetic 
oils. Not all leak but its unpredictable until you try. If you get a leak, 
drain the stuff and refill with non-synthetic lube; most leaky seals 
eventually dry up and stop leaking without rebuilding. Good luck- J Deryke
