97 Park Ave - Supercharger Oil

Does anyone know the correct way to service the oil on a PA supercharger?? I am planning on siphoning/pumping out the old fluid, refilling it, driving for a while and then repeating the process to 'flush' the cone out more. If anyone can tell me the correct procedure, or has tips on an easy way to do it please let me know. Thanks in advance. Matt

You really only need to empty and refill, but what you're planning to do sounds like a winner to me!

I just pump it out and refill. Two bottles.

Stuff comes out is nasty. The oil itself is clear.
