i figured I'd post this...i change my supercharger oil every other regular oil change. so here goes...

1. The first step to changing the supercharger oil is to remove the engine cover by unscrewing the bolt just above the "3800 Series II Supercharged" text on the cover. Also remove the engine oil crankcase filler cap

2. Next, get your two 4 oz (ounce) bottles of GM Vehicle Care Supercharger Oil, which is part number 1 # 12345982 at any GM dealership or at online retailers. You'll also need a sprayer top and some sort of bottle to hold the old supercharger oil. (i found that an old turkey baster also works) The old oil will really stink so be prepared for that

3. now remove the allen wrench bolt you see located towards the end of the snout. Once you remove the bolt, you can insert your totally clean and dry spray bottle pump head tube. (You don't want to introduce any water or foreign substances into the supercharger oil reservoir chamber of course.)

5. Once you get most of the oil pumped out of the supercharger, try to move the pump's hose around to get any more that is hiding in the crevices of the M90. Then you just have to use a small funnel and carefully fill the supercharger up with oil to just under the bolt threads. Don't Overfill Your Supercharger!
