How often should you start the car when it's parked for a long time?

It is recommended to start the car once a week when it's parked for a long time. If possible, driving it for about twenty minutes is even better, as this helps prevent the battery from discharging and allows various fluids to circulate properly, thereby protecting the engine. Prolonged parking can lead to issues such as battery drain, flat spots on tires, and oil sedimentation. If the vehicle needs to be parked for an extended period and there's no time to start it regularly, disconnecting the negative terminal of the battery can help avoid excessive power loss. When a car remains unused for a long time, most of the lubricating oil adhering to the moving parts will flow back into the oil pan due to gravity, reducing lubrication in critical areas. Without the protective oil film, metal parts are prone to react with oxygen, forming an oxide layer that increases friction and makes starting the engine difficult.
If the car remains stationary for an extended period, I recommend starting it at least once a week, preferably running it for 10-15 minutes. The battery is the heart of the car, and prolonged inactivity causes gradual discharge, especially noticeable in cold weather. Starting the engine allows the alternator to recharge the battery, preventing it from dying due to depletion. Additionally, fluids like engine oil and transmission fluid may settle or oxidize; regular operation helps circulate them, lubricating the engine internals and reducing rust risks. The same goes for tires—prolonged stationary pressure can lead to deformation or pressure loss, causing uneven wear. From experience, developing a weekly startup habit is simple yet effective in avoiding many costly repair headaches. If time is tight, set a phone reminder—a small effort that saves major trouble.
