Oil Change FAQ

Q: What do I need to do when my "Change Engine Oil Soon" message displays?

A: When the "Change Engine Oil Soon" message appears, oil change service is necessary for the vehicle as soon as possible, within the next 600 miles.

Based on driving conditions, the mileage at which an oil change is indicated can vary considerably.  For the oil life system to work properly, the system must be reset every time the oil is changed. DON THORNTON CADILLAC has Certified Service expert technicians who will perform this work and reset the system. Click here to schedule service.

Q: How can I be sure to get the correct type of motor oil for my vehicle?

A:  Consult your vehicle Owner's Manual or visit the Cadillac Certified Service experts at DON THORNTON CADILLAC to be sure you get the proper oil for your vehicle. For 2011 or newer vehicles, dexos1™ Full Synthetic is the recommended oil specification (dexos1™ for gasoline engines, dexos2™ for light-duty diesel engines, 15W40 CJ-4 for Duramax diesel engines). Advantages of dexos1™ Full Synthetic over conventional motor oil include improved oil performance and protection, increased piston cleanliness, reduced oil consumption, and greater viscosity control.

Q: I've heard that I should change my oil every 3,000 miles. Is that still true?

A: The majority of today's Cadillac vehicles are equipped with the Engine Oil Life System, which has made the 3,000-mile oil change obsolete. Depending on the age of the vehicle, driving habits, and road conditions, vehicles with today's advanced engines can go much longer than 3,000 miles between oil changes. Always be sure to check your engine oil level regularly, even with an Engine Oil Life System.

Q: Does regularly changing my oil filter help with the life of my engine?

A: Yes, because it helps ensure your engine is lubricated with clean oil which can help provide optimal engine performance. See your vehicle owner's manual for the recommended oil change interval, or follow the oil life monitoring system, if equipped.

Q: Do I need a new filter every time I get an oil change?

A: Yes, having your oil and oil filter changed, at least as often as recommended by the manufacturer, is important.
