How often should a car be started if left unused for a long time?

[DiRiley]

If a car is left unused for a long time, it needs to be started once a week. The precautions for a car left unused for a long time are: 1. Clean the vehicle thoroughly to avoid spontaneous combustion of flammable or explosive items inside the car after prolonged exposure to sunlight; 2. Ensure the fuel tank is sealed properly without any oil leaks or seepage, and avoid leaving the vehicle under constant direct sunlight, as this can cause the fuel tank temperature to rise excessively, increasing the risk; 3. Drive the vehicle for a certain distance each week to keep it running, which helps the components wear in properly, prevents rust, and clears carbon deposits; 4. Start the engine once a month to help extend the engine's lifespan; 5. Regularly check the battery to prevent excessive discharge.
