use pulstar EF -1 found on ebay, use mobil 1 synthetic 5w -30, extended performance, i also left out a half a quart to reduce windage at crank and indexed my plugs so gap faces intake. add an air raid intake, remove muffler, if you have a 2.2 it will now waste a 2.4. if you have a 2.4, you will shut down pontiac solstices
