Chevrolet recommends that drivers schedule an oil change in 3,000-mile intervals to improve the performance of the vehicle. Cars that require synthetic oil only need oil changes every 7,500 to 10,000 or every 12 months. Drivers should top off the oil periodically to ensure the parts in the engine are lubricated in between oil changes. Routine oil changes are necessary for increasing the lifespan of the vehicle and reducing the risk of expensive repairs that may be needed. Make sure to check your owner’s manual for more information.
