Awww you beat me to it. Unless it's a 2 stroke car, they are totally different. With a 4 stroke, you don't want to burn oil as it is hopefully kept seperate from the combustion chamber. On a 2 stroke, you want to burn the oil for lubrication; no valves, cams, etc so they can get away with it easier than a 4 stroke.
