I changed the SC oil in my supercharger today. I used the spray nozzle off an old bottle of Windex to remove the oil by inserting the plastic hose into the opening and pumping it out through the sprayer. After pumping out as much as I could I was able to put exactly one bottle of oil back in. It came to 4 ounces. Is this about right or did I leave a bunch of dirty oil in there?

I am pretty sure one bottle is correct for the method you used and the year of your car.

EDIT: Looks like one bottle is correct according to this Techinfo article.

Thanks.

One bottle for 92-95, two bottles for 96 and newer.
