Modern engines feature modern conveniences. The GM Oil Life Monitoring System takes the guesswork out of when you need your next oil change. When the CHANGE ENGINE OIL SOON message displays in your instrument panel, it’s time to book an appointment. In some cases, the Oil Life Monitoring System might not indicate the need for vehicle service for up to a year.
For added convenience, you can also keep track of your vehicle’s oil life with the myChevrolet®, myBuick®, myGMC®, or myCadillac® apps, as well as book your next oil change when the time comes.
Since lack of proper engine oil maintenance can potentially damage your engine, imposing costly repairs, we’ve made it easy to schedule an oil change. Enter your postal code and simply choose a Certified Service location near you.
