If your using synthetic I assume you have a ZT not a clutch type eg auburn...if thats the case, you dont need the additive anyway.

Just my 10bolt. I didn't think you needed to, but I've read some guys do it anyway with synthetic amsoil.

Torsen diff does not require LS additive, but is ok to use.

Clutch diff requires LS additive.

Most synthetic gear lube says "LS" on the bottle, this means the LS additive is already mixed in.
