HOW TO CHANGE THE SUPERCHARGER OIL ON A GM 3800 SERIES II V6
just a quick instructional video of how to properly change the Supercharger oil on your 3800... some people say just to re-top off your Supercharger, but many owners as well as a good number of master mechanics ive talked to about it that worked on these cars, they say to full out replace it by draining it and putting new oil in, simply because if you know anything about oil youd know that it breaks down over time especially because of heat and friction. new oil handles it better and keeps it properly lubricated and cooler temperature. old oil will be dirty, maybe burned, and possibly ineffective if broken down enough over time. which method you trust is up to you, im not saying either method is right or wrong, this one just makes more sense to me, therefore thats the one i do on my car so we made the instructional video for this, if you choose simply to top off your oil, do all the same steps just dont empty the old oil first.

Weird 3800 Engine Noise
Top swapped 01 impala 3.8L. XP Hot Cam. 2.5" Down Pipe. Fender Well Intake.
It seems to always make this odd noise I simply can't put my finger on.
Things that I know it is NOT:
Acc. Belt Tensioner,
S/C Belt Idler Pulleys,
S/C Belt Tensioner.
And I don't believe it's the A/C as it makes the same noise with the clutch
engaged or not.

How to change your GM 3800's supercharger oil
Really easy! Takes no more than 30 minutes to do. Everything you need is
less than $30 with the right tools.
Supercharger oil: 4oz bottles are
$10-$12 at your local GM dealership. Need 2 bottles. You only need 6 out of
Vacuum pump: usually a free rental at some auto parts stores(such as
autozone) but some lack the cup. Tool costs around $30 to buy
Buy a inexpensive trigger spray bottle. Put the hose end of the trigger in
the Supercharger and spray into the
bottle. Takes longer, but is cheap!
3800 Series 2 make your own fenderwell intake for less then $100
Build your own fenderwell intake for way less then $100
Support 3800 vendors. I dont work for any of these guys but without them a
lot of us wouldnt be able to mod. Our cars are not supported by the big
aftermarket companies so heres a quick plug for the 3 vendors left.
Iv been hearing a noise comeing from the engine bay so i took a short video
for people on the Grand Prix forums to take a listen so they can determin
what the problem is.Thanks to this video i figured out its Supercharger coupler that wore out.
