How often should you start a car that is parked and not driven?

If a car is parked and not driven for half a month, it should be started once. When a car is left unused for too long, it may have difficulty starting. Even when a car is turned off for an extended period, the battery still discharges. Over time, the battery can become completely drained, and its lifespan may also shorten. Components like tires, which are made of rubber, are prone to damage. If a car is left parked for too long without being driven, the tires may develop cracks. Therefore, leaving a car unused for extended periods can indeed lead to certain issues.

When my car is parked and not in use, I start it up every two weeks or so, letting the engine run for 10 to 15 minutes each time. I learned my lesson before when I didn't start it for a month while on a business trip—the battery was completely dead, and I had to call a tow truck and replace the battery, which was both troublesome and costly. Now, I’ve developed this habit because starting the car not only charges the battery but also keeps the oil circulating, preventing internal engine parts from rusting or seizing. For older cars or during winter, the starting frequency should be even higher, as temperature fluctuations can easily affect battery life. At the same time, I take the opportunity to check the tire pressure to prevent deformation from prolonged parking. In short, regular starting saves hassle—don’t wait until the car has problems to regret it.

As an experienced long-term driver, I recommend starting your car at least every ten days when it's not in use and taking it for a short drive. If the engine isn't running, gasoline can settle and deteriorate, and the battery will lose its charge quickly, which can be troublesome once depleted. This is my usual practice—starting the car and driving a few kilometers to keep the entire drivetrain active. Don't forget to check the fluid levels and inspect under the hood for issues like rodent nests. Prolonged parking in summer can lead to heat-induced aging, while in winter, more frequent starts are needed to prevent freezing damage. These simple habits can protect your beloved car and extend its lifespan.

For me, the most critical issue is battery health. If the car remains stationary, the battery might discharge completely in about two weeks, so I make it a habit to start the car weekly. Idling for 10 minutes is enough to recharge the battery, preventing the embarrassment of an unexpected power loss. Additionally, remember to check the dashboard warning lights to ensure no abnormalities, and unplug some car accessories if necessary to reduce power consumption. For long-term parking, also watch out for tire deformation or dust accumulation. Regular startups and simple checks can save you from costly repairs later on.

My approach is to start the engine every 14 days during parking, running it for 10 to 15 minutes each time to recharge the battery and maintain fluid activity. It's even better to take a short drive to exercise the brakes and suspension system, preventing issues from prolonged inactivity. For long-term parking, use a car cover to prevent dust buildup, check tire pressure to avoid excessive deflation, and in winter with low temperatures, starting it weekly is safer. Don't leave it untouched for over a month; otherwise, it's advisable to disconnect the battery's negative terminal. These small actions are practical and easy to do.

Based on years of car ownership experience, I adjust the starting frequency according to seasons. In cold winters, I start it weekly since batteries drain faster and engines are prone to freezing in low temperatures. During hot summers, starting every two weeks suffices, but I choose cooler periods to avoid extreme heat. Modern cars have numerous electronic systems that may trigger error codes if left idle too long, so I use a mobile app to set reminders as backup. During startup, I also check fluid levels and tire pressure, ensuring everything is normal before shutting down. This prevents component aging from prolonged parking, saving money and giving peace of mind.
