How often should I start my car if it's not used for a long time?

If your car is not used for a long time, it is recommended to start it once a week for about 10 to 15 minutes. This not only charges the battery but also allows you to check for any abnormal engine conditions. It would be even better if you can drive it for about twenty minutes, as this prevents the battery from being undercharged and ensures that various fluids are properly circulated to protect the engine. If the vehicle needs to be parked for an extended period and you don't have time to start it regularly, you can disconnect the negative terminal of the battery to avoid excessive power loss. During long-term parking, besides regular battery maintenance, other car components such as engine oil, coolant, brake fluid, and power steering fluid also require periodic cleaning or replacement.
My previous car sat unused for over a month, and when I tried to start it, the battery was completely dead—I had to call for roadside assistance, what a hassle. Since then, I've learned to start it every two weeks. On a nice day, I'll run the engine for at least 15 minutes to charge the battery and circulate the oil, while also moving the car slightly to prevent flat spots on the tires. For cars left idle long-term, fluids can settle, affecting lubrication; after starting, the engine feels smoother. Remember to do this in a safe place—don't run the car in an enclosed space to avoid exhaust buildup. My little tip: maintaining this habit can save you a lot on repair costs.
