How often should a car be started if it is not driven for a long time?

If a car is not driven for a long time, it is recommended to start the engine every one to two weeks and then drive a certain distance. The driving distance should not be less than 20 meters. This allows the generator to charge the battery, lubricates the internal components of the engine and transmission, and prevents flat spots from forming on the tires. When a car is parked for an extended period, the fluids in the transmission and engine cannot circulate, and the internal components of the transmission and engine will not be adequately lubricated. If a car is left unused for a long time, the paint is prone to issues. If parked outdoors without a car cover, prolonged exposure to wind, sun, dust, fallen leaves, and bird droppings—if not cleaned promptly—can seep into and corrode the paint, causing it to lose its luster and even leading to aging and peeling.
My car at home often sits idle, and I have experience to share with everyone: vehicles left unused for long periods need to be started regularly. Start it about once every weekend, let the engine run for over 20 minutes, and it’s best to drive it a short distance on the street. Why is this necessary? First, the battery slowly discharges—without starting, it could be completely drained within two weeks, leaving you unable to start the car and requiring a tow or battery replacement, which is a hassle. Engine oil also tends to solidify and separate, leading to poor lubrication and increased wear. In northern winters, the battery is more prone to freezing and failing. Tires under prolonged pressure can deform, so moving the car helps maintain balance. Based on my experience, pay attention to whether the engine sounds smooth when starting and check if the lights are working properly—this can help detect issues early. In short, making it a habit to start the car every 7-10 days can save you a lot on repair costs and unexpected risks.
