the Oil in your supercharger should be changed every 30k miles, using GM supercharger oil, best way to get it out of there is with a turkey baster, and when you go to fill it up the reccomended amount is 6 oz of fluid which is a bottle and a half.

thanks for the advice, i just got the car not to long ago and i am not sure if it has ever been changed. i will get that done asap then!! once again, thanks

yeah when you take the plug out give the fluid a whiff, if it smells horrible then it needs to be replaced.

If you want to make it cheaper on you buy it zzperformance.com there bottle is 6 oz and 9.95 as to 2 bottles of GM which are 4 oz a peice which you pay 7 a peice for, just a thought!
