how do you check the supercharge oil?

i could be wrong, but isn't the S/C linked with your regular oil system?  

hell no.....to ckeck the oil level in the supercharger requires a special tool...check with gm for availability...hopefully this helps and the skies remain blue...

you can actually just jam your regular dipstick in there,   have it running and stick the dipstick in the slots in the side of it  and see where it's at.. it should only be about half of a full engine oil
