Well im putting a Zexel Torsen Posi/4:11's in this week. how many bottles of limited slip additive do i need to use? I have used just one in the past when i changed my rear end fluid, but i keep reading 2 bottles in various places..? So what is it really? Im thinking i just need one bottle.

Also what are some good gear oils you guys had good experience with

 

now i am reading that the Zexel doesnt need the additive....can any one help on this?

 

I just put in one bottle of limited slip additive when I change my gears and they are working fine, but I don't have a Zexal Torsen posi so I'm not sure if they need additive or not.

 

i just pured in that royal purple stuff and says it already has the limited slip additive mixed in.

 

My owners manual says to use one bottle, with the GM synthetic. You may not need it depending on what fluid your using - I'd toss one in just to be safe.
