Could someone lead me in the right direction please as to where I can find information about how to change the oil in the supercharger for a 1997 Regal GS?

Just follow the procedure below. Stop at the part where it shows the extraction of the old SC oil using a syringe or turkey baster. Use GM supercharger oil only, part # 12345982. You'll need 2 bottles which are 4 oz each. It holds 6 oz.
