A finely tuned performance machine like your Cadillac deserves regular attention to keep it running at its peak. The Certified Service technicians at your Cadillac dealer are expertly trained to understand how your Cadillac uses its oil and how it monitors oil life. An oil change performed by a Certified Service expert provides you outstanding service and convenience, with the additional benefit of expertise on your Cadillac vehicle.

When it is time for your next oil change, visit the experts at your Cadillac dealer.


Choosing the proper grade of oil is a critical step in engine maintenance. From conventional to full synthetic, your Cadillac Certified Service experts offer a range of oil types, including ACDelco Conventional Oil, ACDelco dexos1® Synthetic Blend, and Mobil 1™ Full Synthetic.

The advanced technology in your Cadillac helps maintain performance with diagnostic tools that indicate the optimal time for service. For example, most Cadillac vehicles are equipped with the engine Oil Life System (OLS). This system interprets your vehicle’s speed and engine temperature and continuously monitors operating conditions—which helps determine when it’s time for an oil change.

The OLS also monitors your personal driving habits and the area’s climate conditions to let you know precisely when to come in for an oil change. As soon as the OLS light comes on, it’s time for service—it’s that simple.

Your Certified Service technician will reset your Oil Life System after an oil change. To reset the system yourself, ask your technician how, or consult your Owner’s Manual if necessary.
