I use Lucas 80/90, but pretty much any quality 75/90 oil will be fine. Mobil1 synthetic is another popular choice, on the higher end of the price range is the Redline and Royal purple stuff.

It takes 2 quarts. Exactly. If you use a synthetic, they normally have the additive in them. They will say on the side of the bottle. Otherwise, you have to add one bottle of the GM additive, which the autoparts store also sells.
