How much oil and what type is needed for a Cadillac Seville?

The amount of oil and type required for a Cadillac Seville depends on the model year and engine type of the vehicle. Here are the general guidelines:

For Cadillac Seville models with a gasoline engine, the recommended oil type is 5W-30 synthetic oil, and the recommended oil capacity is approximately 7.5 quarts (7.1 liters) for most model years and engines.

For Cadillac Seville models with a diesel engine, the recommended oil type is 15W-40 diesel oil, and the recommended oil capacity is approximately 8 quarts (7.6 liters) for the 5.7L diesel V8 engine.

However, it is always recommended to consult the owner's manual or a certified Cadillac service center to determine the exact oil capacity and type for your specific model and year.

It is important to use the correct oil type and amount for your Cadillac Seville, as using the wrong oil or exceeding the recommended oil change interval can lead to engine damage or decreased performance. It is recommended to change the oil at least once a year or every 7,500 miles, whichever comes first, for gasoline engines, and every 10,000 miles or every year, whichever comes first, for diesel engines. Always follow the manufacturer's recommended oil change interval and use the recommended oil type to ensure the best performance and longevity of your Cadillac Seville.
