For a 2010 Cadillac CTS3 6, you should use the oil type 5w-30. It's important to remember to change your oil when necessary — typically every 5,000 to 10,000 miles is a good guideline. Neglecting this maintenance can lead to engine problems. Quality oil is crucial for keeping your engine running smoothly. If the oil isn't addressed, you may notice a strong burning odor, which should be checked immediately to prevent any potential danger, like an engine explosion. Poor-quality oil can result in engine failure, lower gas mileage, and unusual knocking sounds from the engine.
Cadillac suggests using 5w-30 synthetic motor oil for a 2010 Cadillac CTS with a 3.6L engine.
