The windex bottle method suggested is the one i use. Just stick it in there and squeeze till all the oils out. Ive never used engine oil in my supercharger, but alot of people have with zero failures i've seen. I still use the gm supercharger oil. Its 12 bucks a bottle at my dealer and you'll need 2 bottles. Pricier than engine oil, but for something that you change less often than your trans fluid it'* not all that bad. This coming from the guy that changes his trans/sc fluid once a year lol.

An fyi the sc snout is aluminum so make sure you don't cross thread the plug when you put it back in.

thanks for the info. tomorow morning im taking the sc. back off cause im still getting a a gringing noise at idle. when i change the clupler i never greesed the needel berrings in the back of the supercharger i hurd you have to use aircraft greese but i cant find it anywhere, will reg. high temp berring greese work??? and im also going to cut the triangle opening a little bigger does that increse horspower or am i waisting my time????
