Camera and Vette use different type of locking differential. As why additive is needed.

Ok. So I guess I should purchase fluid such as Amsoil severe gear or Royal Purple that don't have the ls additive pre mixed. I've noticed most of the gear oils such as mobil 1 have ls additives.

thanks by the way

Since you don't have the G80 option you can run whatever you want.
Additive, no additive won't make a difference in differential operation.
