How often should a sedan be started if it's not driven for a long time?

Under normal circumstances, if a car hasn't been driven for a week, it should be started for 10-15 minutes. This not only charges the battery but also checks for any abnormalities in the engine. It's important to let the vehicle run for a sufficient amount of time; otherwise, the battery may not recharge enough to compensate for the power used during ignition. Here are some precautions for cars that are not driven for extended periods: 1. Always park the vehicle on a flat surface to prevent tire deformation due to uneven pressure and ensure that the fluids inside the car remain balanced and functional. 2. If possible, park the car in a garage to protect the paint from damage. 3. Start the car once a week, and if possible, take it for a short drive to keep it in good condition. If this isn't feasible, consider disconnecting the car battery to prevent it from draining over time. 4. After starting a car that hasn't been driven for a long time, it's advisable to let it warm up for about 10 minutes to ensure all engine components are properly lubricated and functioning correctly.
I understand this issue deeply because I often travel and leave my car idle. When a sedan is parked for a long time without moving, the battery will gradually discharge, the engine oil will settle causing increased engine wear, and the tires may even deform. Generally, it's recommended to start the car every 1 to 2 weeks and let it run for 15 to 20 minutes. In winter or humid environments, increase the frequency to once a week to prevent moisture damage to the electrical circuits. Don't just let it idle when starting—drive a short distance to get the transmission and brakes moving, and check that the tire pressure isn't too low. Before storing, fill up the fuel tank to reduce moisture and consider using a battery charger for extra peace of mind. In short, stick to a maintenance routine every 10 to 14 days to avoid a dead battery or seized engine, otherwise, the repair costs can be hefty.
In principle, prolonged inactivity poses multiple risks for vehicles. The battery self-discharges at 1-2% daily, potentially depleting and becoming irreparable within one to two weeks. Engine oil settling can lead to cold-start component wear. Moisture in electrical circuits may cause short circuits, while insufficient tire pressure results in flattening and deformation. The optimal practice is to start the car every 7 to 10 days, allowing it to run for 10 to 15 minutes to warm up the engine and recharge the battery. During rainy seasons, reduce the interval and enhance ventilation to prevent rust. For long-term storage, monthly startups are acceptable, but exceeding four weeks increases risks. Simply put, regular startups maintain battery charge and lubrication, while moving the car to rotate wheel positions minimizes deformation forces, offering more comprehensive vehicle protection.
