How often should I start the engine during long-term parking?

During long-term parking, it's recommended to start the engine once a week. If possible, driving the vehicle for about twenty minutes is even better, as this helps prevent battery discharge and allows various fluids to circulate properly, thereby protecting the engine. Extended parking can lead to issues such as battery drain, flat spots on tires, and oil sedimentation. If the vehicle needs to be parked for an extended period without regular starting, you can disconnect the negative terminal of the battery to avoid excessive power consumption. When a car remains unused for a long time, most of the lubricating oil clinging to engine components will flow back to the oil pan due to gravity, reducing lubrication in moving parts. Without proper oil film protection, metal surfaces may react with oxygen to form oxide layers, increasing friction and making engine startup difficult.
As an experienced driver with decades behind the wheel, I've learned that a car's condition often deteriorates after prolonged parking. Generally speaking, starting the engine every two weeks is the safest approach - letting it idle for 10 to 15 minutes is sufficient. This isn't unnecessary fuss; it charges the battery to prevent starting issues when you return, while also circulating oil to lubricate internal engine components and prevent rusting or stiffening. For parking periods exceeding one month, perform additional tire checks as prolonged pressure can cause deformation and slow leaks. Be extra diligent in cold weather, as thickened fluids may cause starting difficulties. Finally, routinely inspect the cabin for rodent damage to wiring - these small precautions can save significant trouble and repair costs. Remember, prevention is better than cure - just like people, cars need regular movement to stay in good condition.
