How Often Should You Start Your Car?
3 Answers
It is recommended to start the car at least once every two weeks, while some vehicles may require starting once a week. Leaving a car unused for extended periods is detrimental, as it accelerates the aging of certain components and tires. If the battery is old, prolonged inactivity can lead to battery discharge, thereby reducing its lifespan. Generally, it is advisable to start the car once a week and let it idle for a few minutes. Here are the reasons for doing so: 1. When a car remains inactive for a long time, most of the lubricating oil adhering to the components that require lubrication will flow back to the oil pan due to gravity, reducing the lubrication of moving parts. 2. Without the protection of an oil film, metal is prone to react with oxygen, forming an oxide layer that increases friction and makes starting difficult. 3. If the battery does not receive a charge over a long period, the sulfation process of the battery plates intensifies, increasing internal resistance and shortening battery life. 4. Due to the self-discharge effect of the battery, the terminal voltage may drop below 85%, rendering the battery irreparable.
My wife and I mostly commute to work without driving, only using the car on weekends. Once, I forgot to start the car for three weeks while on a business trip, and when I returned, it wouldn't start at all, costing me several hundred dollars for a new battery. Since then, I've made it a habit to start the car once a week, letting the engine run for about 15 minutes each time. This not only charges the battery but also allows the oil to circulate and lubricate various engine components, preventing rust or seal aging. Especially in cold regions, it's even more important to be diligent in winter, as low temperatures can cause the battery to discharge faster. Living in the north, I now habitually start the car every Sunday morning. While at it, I check the tire pressure and coolant level. This small habit keeps my car running smoothly, extends its lifespan, and saves on repair costs. The key is to treat starting the car as part of routine maintenance—simple, easy, and highly effective.
When I first bought my car, I was naive and thought that if the car wasn't being used, it didn't need any attention at all. After returning from a trip, the car wouldn't start, and after seeking help from a mechanic, I learned that the battery had completely discharged and needed to be periodically started to recharge. Now, I start the car for about 15 minutes every 10 days or so, which is very helpful for beginners: it not only maintains battery health but also prevents flat spots from forming on the tires due to prolonged parking and keeps the fuel lines from clogging. I work in the city and drive less and park more, but since adopting this habit, my car has had no unexpected breakdowns. The engine sounds much smoother when starting, and I've also learned that in higher ambient temperatures, the frequency can be slightly reduced, but overall, it protects my investment. A simple step to learn with quick and significant benefits, it's perfect for novice drivers like I was back then.
