It goes into the Supercharger's snout. There is a plug in the snout, which can be removed and that is where you would change the oil. I think the manual says it needs to be changed every 60,000 miles, but the GP community normally changes their SC oil every 30,000 miles (Probably the best thing to do, if you are running a smaller pulley other than stock).
If you do change it, wear a gas mask. The old supercharger oil wreaks like there is no tommorow :lolsign:
