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

It is recommended to start a car every two weeks if it's not driven for a long time. Here are some tips about long-term car storage: Recommendation to start every two weeks: This prevents the lubricants in the vehicle from affecting the car due to prolonged inactivity. When a car remains unused for extended periods, most of the lubricant that should be coating the moving parts will flow back to the oil pan due to gravity, reducing lubrication effectiveness at various moving components. Additionally, the battery may lose charge, causing sulfation of the plates and shortening its lifespan. How to store a car for long periods: Before parking the car, both the exterior and interior should be thoroughly cleaned. Applying wax or a protective coating can help prevent paint corrosion. If possible, store the vehicle in a garage. If parked outdoors, at least use a car cover to protect against sun, rain, and debris like fallen leaves that can damage the paint. For vehicles parked long-term, avoid engaging the parking brake too tightly. The brake system can chemically react with moisture and oxygen in the air when idle for long periods, combined with rainwater erosion, causing rust on brake discs and pads. If they stick together, this can impair braking performance and may lead to wheel lock-up upon restarting.
I've repaired many cars before and heard experts say this multiple times. For cars that aren't driven for long periods, such as being parked for over two weeks, it's best to start them every seven to ten days. After starting, let the engine run for 10 to 15 minutes. This helps recharge the battery and prevents it from being completely drained and damaged, as batteries slowly self-discharge over time. If left unchecked, the battery will die, making it difficult to even open the door or start the ignition. Tires are also prone to issues—remaining stationary for weeks can cause them to flatten or deform, affecting balance and safety. I recommend regularly checking tire pressure to maintain the standard value. Engine oil and coolant can also settle; starting the car allows them to circulate, preventing rust on parts. Last time I went on a business trip and didn't touch my car for a month, the battery was dead when I returned. So if you plan to park it for even longer, using a battery charger for maintenance can save both hassle and money.
Our car often sits unused in the garage. I've found that if the car is parked for more than ten days, it's best to start it up. After starting, let the engine run for five to ten minutes, which helps prevent battery drain. A dead battery makes it difficult to start the car, leaving you in a passive position during emergencies. As a family user, I always remind my children to regularly check the car's condition to avoid sudden issues. The fuel system is also important, as fuel can oxidize and deteriorate over time, affecting performance. Tires left in one position for too long can flatten and leak, shortening their lifespan. It's recommended to start and maintain the car once a month or purchase a simple battery maintainer for charging. Safety first—don't skimp on this effort.
