Nobody knows your vehicle better than the GMC Certified Service expert technicians. As trained professionals, they can help recommend the optimum maintenance schedule for your GMC vehicle. Advanced technologies, such as the engine Oil Life System (OLS), also keep you well informed. The OLS calculates oil deterioration and indicates when an oil change is needed, which may affect the frequency and type of other services required. And now, with GMC Pro Grade Protection two maintenance visits* are included in the purchase or lease of select vehicles, within two years or 24,000 miles.
