GMC Vehicle Maintenance Schedule and Owner's Manuals from the Certified Service experts


Determining the right time for vehicle maintenance can be confusing—especially when your GMC seems to be running just fine. The Certified Service experts make regular vehicle maintenance as convenient and simple as possible.

Depending on the vehicle you drive, your vehicle maintenance schedule may vary. You may benefit from technologies such as the engine Oil Life System (OLS). The Oil Life System calculates oil deterioration and indicates when an oil change is required, which may affect the frequency and type of other services required. If you do not have this technology, the Certified Service experts at your GMC dealer can help recommend the right maintenance schedule.


A great source for required service and vehicle maintenance information, including your maintenance schedule, is your vehicle’s GMC Owner Manual. If you need a replacement manual, locate your brand below to purchase or download (subject to availability) the owner and service manuals you need.
