How often should a sedan be driven when left unused?

It is recommended to start the car once a week and drive it every two weeks for about 3-5 kilometers. More relevant information is as follows: 1. The main issues with leaving a car unused for a long time are that the battery may lose charge if not recharged regularly, making it difficult to start the car, and the tires may deform due to uneven pressure from being stationary in one position for too long. It is best not to leave a car parked continuously for more than two weeks. 2. Before parking the car for an extended period, the exterior and interior should be cleaned thoroughly. Applying wax or a protective coating can help prevent paint corrosion. If possible, store the car in a garage. If parking outdoors, at least cover the car with a car cover to protect it from sun, rain, and damage from debris like fallen leaves.
It is generally recommended to start and drive a sedan at least once every three weeks if it remains stationary. Personally, when I don’t drive for an extended period, my biggest concern is the battery draining. Over time, the car battery will gradually discharge on its own, and after about a month, it usually won’t start. Additionally, the tires, constantly pressed in the same spot, are prone to deformation and air leakage, which can cause the steering to feel off when driving again. The engine oil also settles, leading to poorer lubrication upon restarting. I usually try to move the car every week, driving for at least fifteen minutes to warm up the engine and circulate the oil. If I really don’t have time, I’ll ask a neighbor to take it for a short drive. A car needs to stretch its legs every now and then.
I think driving once every two weeks is appropriate. If a car sits for too long, the brake discs can easily rust, especially after rainy days, making an annoying squeaking sound when braking. Additionally, tire pressure slowly leaks over time, and if parked for more than two months, you'll likely need to refill the air. Another issue is the deterioration of fluids in the car, particularly gasoline, which can form deposits and clog the fuel injectors over time. It's best to drive for about 20 minutes each time, taking a quick spin on the highway. This allows the engine to warm up, evaporating moisture, which is also good for the exhaust system. Moreover, the air conditioning system needs regular activation to dehumidify and prevent mold growth. Regularly driving the car can save a lot of maintenance trouble later on.
