It is recommended to change your supercharger oil every 30,000 miles or 36 months whichever comes first. Depending on how you drive your car. If its more aggressive then I would change it sooner. Watch out though, that stuff could gag a maggot!! Lol. If your going to change it you will need some kind of way to get it out of there. Like an eye dropper similar to what you would feel an animal with. or some kind of seringe with a hose. I used a seringe from a hospital, worked great. Two bottles will fill it up. FYI, it is full when the oil reaches the bottom of the threads on the plug. Hope this helps.
