i just finished readin the posts about 16v diff oils and everybody recomends redline but i dont have acces for redline, instead i bought motul 90pa rear axle oil and on the label it says limited slip
in addition i bought petrochemical pmt-3 friction free complete additive package and its says cointains molybdenum disulfide, my questions are :

did i buy the right stuff?
is the moly stuff the one needed for the LSD diff?
how much of the additive should i use?

thanx a lot
