need some diff help

hey guys im droping off my car for a ta install and i might have the rear end oil changed and im wondering what diff i have.
if the rear of the car is in the air and in neutral the wheels both spin the same way. i read a thread a wile ago but i cant find it now and it said that if both wheels spin the same way i have a certain diff and if the wheels spin oposite then its a certain kind of diff.
i need to know what gear oil to buy and if i need the additive or get royal purple or what.
thanks in advance guys
