The 2000 Cadillac DeVille requires SAE 5w-30 motor oil, holding 7.5 quarts with the filter. Oil plays a vital role in reducing friction, wear, and internal corrosion in the engine. The estimated cost of an oil change for your DeVille is approximately $40 to $50 for labor and $100 to $110 for parts. It is recommended to get an oil change every 6,000 miles or once a year, whichever comes first. Signs indicating a necessary oil change include engine noise, transmission issues, shaking at idle, smoke from the exhaust, decreased fuel efficiency, and illuminated Check Engine or Oil Change warning lights.
