i'm about to get mine finally running soon, and i guess it's not going anywhere without some oil in it....

what do people use that have either the cusco unit or ralliart 5-speed? i wonder if there is a different oil for each? i only need something that will work cheaply, coz i gotta change it in 1000k's anyway.

what type of diff is it?

i have a cosco lsd and had to get GOOD OIL mine is some red line syn rally art can use stock oil but if you put stock oil in a cosco diff you will hear some realy bad noises.
