The frequency of engine tune-ups can vary depending on your vehicle's make, model, and age. Generally, it is recommended to schedule a tune-up every 30,000 miles or every two years, whichever comes first. However, if you notice any performance issues such as decreased fuel efficiency, rough idling, or difficulty starting, it may be time for a tune-up sooner. Consult with the professionals at Christian Brothers Automotive Spring Klein to determine the best maintenance schedule for your specific vehicle.
