How Often Should You Start a Car That Hasn't Been Driven for a Long Time?

Generally, a car that is not in use should be started once a week. If left unused for 10 days, it's not a big issue, but parking conditions should be considered—preferably in a sheltered area. Below are relevant details: 1. The main problems with long-term car storage are: the battery may lose charge if not recharged regularly, making it difficult to start the car; tires left in one position for too long can lead to uneven pressure distribution and deformation. 2. For prolonged parking, the most critical component is the battery. Even when unused, a battery discharges on its own. Typically, a battery can fully discharge within three months. Therefore, it's advisable to disconnect the battery if the car won't be used for an extended period; otherwise, electrical components in the car will continue to drain power.
I have a car at home that often sits idle. Once, after being parked for two months, it wouldn't start, and the battery was completely dead. Since then, I've made it a habit to start the car every two weeks, letting the engine run for at least 15 minutes, and sometimes driving around the neighborhood for about five kilometers. This helps prevent the battery from deep discharge damage, while also allowing the engine oil to circulate and lubricate the components, avoiding rust. Tires can deform if left in one position for too long, so short drives help distribute the pressure evenly. In summer, it's best to park in the shade to reduce issues with the fuel lines drying out; in winter, more frequent starts are necessary as the battery discharges faster in cold weather. Regular startups also allow you to check if the brakes are responsive—safety first. Keeping the car in good condition ensures peace of mind when traveling.
