How Long Can a Car Sit Without Being Started?

[OTyler]

After being parked for a week, the car should be started once to recharge the battery. It is recommended to start the car every two weeks and drive it for 3 to 5 kilometers to maintain its performance. Prolonged inactivity can lead to various issues, including paint damage, battery drain, rubber aging, and fluid deterioration. Below are suggestions for long-term vehicle storage: 1. Clean the vehicle thoroughly: Before parking, clean both the exterior and interior of the car. Applying wax or a protective coating can help prevent paint corrosion. If possible, store the car in a garage. If parking outdoors, use a car cover to protect it from sun, rain, and debris like fallen leaves. 2. Avoid engaging the parking brake tightly: For long-term parking, it is best not to engage the parking brake too tightly. The brake system can react with moisture and oxygen in the air, leading to rust on the brake discs and pads. This can cause them to stick together, affecting braking performance and potentially causing wheel lock-up upon restart. 3. Increase tire pressure: Raise the tire pressure to around 2.8 to prevent tire deformation. Additionally, park on a flat surface to minimize tire damage. Parking on uneven surfaces for extended periods can cause tire deformation. 4. Prevent battery drain: Even when not in use, car batteries self-discharge. A good battery may deplete in about three months, while lower-quality ones may discharge faster. To avoid total discharge and battery failure, start the engine every 1-2 weeks. This also helps prevent internal engine rust. 5. Start the car periodically: Vehicles left unused for long periods may experience oxidation of engine oil, brake fluid, coolant, and electrolyte. Regularly starting the car and driving it briefly allows the engine to reach normal operating temperature. Before using the car again, replace the engine oil and other fluids and perform appropriate maintenance.
