Regular oil changes can help optimize the performance and fuel economy of your Chevrolet car, truck, or SUV. Many older-model Chevrolet vehicles, including those manufactured without or before the creation of the Oil Life Monitoring System, require oil changes at 3,000-mile intervals. However, thanks to advances in engine technologies, newer models may have a longer range between oil changes. Always refer to your Chevrolet vehicle Owner’s Manual for oil-change intervals for your specific vehicle.
