How often should a vehicle be started if left unused for a long time?

It is recommended to start the vehicle every 14 days if it remains unused for an extended period. If idling without driving, it is advisable to let the engine idle for ten minutes and then gently press the accelerator for two minutes to warm up the engine. This helps prevent the relatively shortened service life of components such as the vehicle battery, tires, and engine oil due to prolonged parking. This practice can prevent flat spots from forming on the tires, lubricate the engine and transmission, and allow the alternator to charge the battery. It is not recommended to leave the car unused for long periods, as this can cause damage. A vehicle left unused for a long time may easily experience battery drain, and prolonged battery discharge can affect its lifespan.

My car is usually parked in the home garage, and before every international trip, I make sure to start it at least once every ten days. The reason is simple: the battery slowly discharges when idle, especially in modern vehicles with numerous electronic devices like anti-theft systems or Bluetooth connections, which continue to consume power even when turned off. If left unused for too long, it might not start after two weeks, and the battery could be completely dead, requiring replacement. When starting, I let the engine run for about 15 minutes, keeping the RPM around 1500. This helps recharge the battery while circulating the oil to lubricate engine components, preventing rust or sticking. The parking environment also matters—damp areas accelerate corrosion—so I recommend checking tire pressure and clearing surrounding debris. In short, regular starting is a necessary habit to maintain vehicle health.

Having driven for twenty years, I am well aware of the troubles of leaving a car unused for long periods. Issues like battery self-discharge, fluid sedimentation causing starting difficulties, or tire deformation affecting safety are common. My routine is to start the engine once a week, letting it idle for about ten minutes, and then taking a short drive to exercise the suspension system. Based on my experience, the interval can be extended to two weeks in summer, but should be shortened in winter due to accelerated discharge in cold temperatures. If forgotten, the battery is usually dead after a month, and replacing it is costly. It's best to use a smart charger plugged in for peace of mind. Regular maintenance not only prevents unexpected issues but also enhances driving comfort.

As someone who travels frequently on business, leaving the car parked at home unused can lead to issues. I've set a rule: start the engine every seven days. After ignition, let it idle for ten to fifteen minutes - enough time to charge the battery and lubricate internal engine components. Though brief, this routine effectively prevents excessive battery drain and part corrosion. I also check the lights and fluid levels to ensure everything's in order. This simple habit guarantees smooth starts every time, eliminating last-minute worries before trips.
