how full should the oil in the supercharger be

I believe there is a plug where you can insert a fingertip to check this. I would contact the dealer service department, they should be able to tell you.

yes,with hood up looking at engine next to snout on supercharger look right you will see a allen type nut remove and if you can see it or as littlehorn said insert finger if oil is on finger you ok,if you see nothing,go to dealer the sc requires a special oil.

Just in case some people don't know. How often should this oil be changed? and can it be changed? Just thought i'd ask.

no the only time you change it is if the top of supercharger gasket starts leaking.the reason i know about the supercharger is i own a 89 t bird supercoupe with 3.8 supercharged engine wich is standard engine for the 89 to 94 sc t bird.picts of mine in my garage then picturies.
