Ooops, sorry... thought FSS was in use by '97. So you don't *have* to use synthetic but it's highly recommended. And if you are using synthetics, you cannot check the oil level a few minutes after shutdown - period. You must do it when cold. It's not that hard to do it cold! The synthetics cling to interior surfaces for hours when warm, many people have observed a half-quart difference or more between cold and warm measurments...
