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 8oz.
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!
