How often does a car need tune up?

The frequency of car tune-ups depends on various factors such as the car's age, mileage, driving conditions, and the manufacturer's recommendations. Older cars may require more frequent tune-ups, while newer vehicles with advanced engine management systems may need them less often. Generally, a good rule of thumb is to have your car tuned up every 30,000 miles or 24 months, whichever comes first. However, some specific components within the tune-up may require attention more frequently, such as spark plugs, fuel filters, and air filters. It is always best to consult your vehicle's owner's manual or a trusted mechanic for the specific maintenance schedule for your car.
