Choosing the proper grade of oil is a critical step in engine maintenance. From conventional to full synthetic, your GMC Certified Service experts offer a range of oil types, including ACDelco Conventional Oil, ACDelco dexos1TM Full Synthetic, and Mobil 1™ Full Synthetic. Ask the Certified Service experts which grade of oil you should use for your specific GMC model. You can also check your Owner’s Manual for the correct grade.
These oils contain a variety of characteristics that affect your vehicle's performance, offer varying levels of engine protection, and can extend the time between oil changes.
