To change the oil in a 1998 Cadillac STS, start by warming up the engine slightly to thin the oil, then turn it off and let it cool for a few moments. Use a wrench to remove the oil drain plug and let the old oil drain completely into a pan. Replace the drain plug, then remove the old oil filter, applying a little oil to the new filter's gasket before installing it. Finally, pour in the new oil through the oil filler cap, checking the level with the dipstick to ensure it’s at the proper level.
