Does maintenance data change by model year on a GMC Sierra 1500?

Yes. This page keeps one model URL and loads the stored specifications for the year you select. The default year is the latest catalog year that has maintenance specifications.

What is the maintenance interval for a GMC Sierra 1500?

This catalog does not store a manufacturer maintenance interval for the GMC Sierra 1500. Confirm service timing in the owner's manual or the vehicle maintenance monitor. Capacities and sizes on this page are not a mileage schedule.

What should I verify before buying parts for a GMC Sierra 1500?

Match the model year and, when the catalog lists more than one engine, the engine. Oil grade, battery group, and wiper position are separate values. A catalog product mapped to the vehicle is not a claim that every engine uses that product.
