For the 2002 Cadillac DeVille, the recommended oil type is SAE 5W-30. If you live in a region where temperatures drop to as low as 0F, consider using SAE 10W-30. When changing your oil, don't forget to replace the oil filter too. Engine oil not only lubricates the engine but also cleans, reduces friction, and prevents overheating. Checking your oil weekly is recommended to ensure you have enough oil. Running your engine with low oil levels can cause damage to the engine and its components.
The recommended oil for the 2002 Cadillac DeVille is Valvoline synthetic motor oil in a 5W-30 viscosity grade and a 5-quart capacity.
