Does my supercharger need to be maintenanced? If so, how and how often? Have read about checking the oil, but how is that done?

Supercharger oil change

I've heard 50K miles, but just changed mine at 28K...it was certainly needed, as the oil was dis-colored and stunk pretty bad! I've been getting 30K as a response from a few other maintenance guru's...I say better to do it sooner than later (especially if you like to use the supercharger as much as I do).

according to gm, the S/C doesnt need to be serviced at all, and the life expectency is ~100k, that being said, it ALWAYS stinks badly, easiest way to change is w/ a syringe and airline hose and suck out as much as you can. It takes 1 1/2 bottles IRRC

I just changed mine, on a 04 ss if you look at the snout of the supercharger


You can go to your dealership or browse online for the supercharger oil which looks like this...



Carefully unscrew that, I would do this when your engine is cold. I found it easier if you have a spray nozzle and just spray it in a water botttle like this image


Get as much as you can out and just refill it with the bottle, I would purchase two bottles and once you do that your all set!

Does anyone know or have pics of the filters?

I have filters for the supercharger. It's a square filter that looks like it goes inline somewhere. GM Part # is 801528 - foam filter it's small too. Does anyone know where they go?
