Hi! I just got a 2way cusco lsd. It has alot of miles but it looks like its still intact and well maintain. Anyways, the person who sold me said the best differential oil is KAAZ. But I can't find any in auto part store, except online ( i dont want to order online and wait like a week to get here

) . Is their any other diff oil brand that sells in auto part store?
Sorry im new.
