supercharger oil

I have an 88 Dech mustang with a paxton supercharger. The p/o # is scratched off so its hard to identify it but i'm pretty sure now its an SN-89. Someone told me it was putting out 4lbs of boost. This sound right?..anyway my question is how do you change the oil on these things? It says on it to use Type "F" fluid and it has a dipstick on the side of it. Thanks!

You can use a turkey baster with a rubber hose on the end and suck the Type 'F' out which is what you got with these superchargers new. Then put the Fluid back in the dip-stick hole. The blowers usually made 5psi but that changes to what is on the car because boost is based on back pressure(load).
