LSD’s need friction modifier additives. They use hyphoid gear oil, similar to whats used in MT transmissions, you just need to get a limited slip additive from a place like PartSource of PI

lmfao no no you dont a vlsd is a closed unit you need no additives.  
only a clutch type lsd needs additive and synthetic fluid.  
you can use dump truck oil if you want lol.
