If a car is parked for about a week, it should be started once. If parked for about half a month, the car should be started and driven for three to five kilometers. This not only charges the but also changes the stress points on the tires when parked, which has no negative impact on the car. If the car is left unused for a long time, it can cause damage to the battery. For long-term parking, the following situations should be noted: 1. The vehicle's paintwork. If the car is parked outdoors for a long time, exposure to wind, rain, bird droppings, and dust can corrode the paint and rubber components. If possible, it's best to park the car in a garage. If a garage is not available, using a car cover can effectively protect the paint. 2. The vehicle's tires. If the car is not used for a long time, the tire pressure should be inflated to the maximum value, typically 2.8-3.0 bar depending on the tire model, to prevent damage from underinflation over time. 3. The vehicle's battery. If the car is not used for a long time, the negative terminal of the battery can be disconnected to prolong the battery's self-discharge time. Alternatively, the battery can be charged once every 1-2 months to prevent damage from internal plate detachment.

I think it depends on the situation, but based on my experience, I recommend starting the car every 7-10 days and letting the engine run for at least 10 minutes. Otherwise, the can easily drain completely. Once I forgot to start it for three weeks while on a business trip, and when I returned, the car wouldn't start—I had to call a tow truck, which cost me a few hundred dollars. If the engine oil doesn't circulate, it can settle and cause significant damage to the engine internals. Additionally, long-term parking can lead to tire pressure loss or other issues. I make it a habit to start the car once a week, checking the lights and dashboard while I'm at it—it's worry-free and safe. Remember, it's better to slightly move the steering wheel or drive a short distance when starting to keep all components active. In colder environments, start the car more frequently, like every 5 days, to avoid freezing the battery. Overall, regular starting saves money and hassle on major repairs, making it easy to maintain the car's condition.

I have driven various cars for many years and understand the core of . Starting the engine for over 10 minutes each week can keep the battery charged, as modern batteries self-discharge about 15%-20% monthly, which can be replenished by idling. The engine lubrication system recirculates oil, reducing component rust. If parked for more than two weeks without starting, tires may develop flat spots, and electronic components drain power quickly. I schedule a fixed weekly startup time, sometimes even taking a small drive around the garage to warm up the car better. In winter or hot weather, more frequent starts are needed, about every five days. For long-term non-use, such as a two-month trip, I disconnect the battery negative terminal or use a smart charger—safe and simple. Regular startups also prevent fuel system issues and extend the car's overall lifespan.

I personally think new car technology makes this easier. Manufacturers recommend starting the car for 15 minutes every 10-14 days, especially for models with alarms or remote monitoring. Apps can remind you of status—like systems I've used that show low battery and prompt you to start idling immediately. Idling consumes little fuel with minimal impact, while protecting the battery from unexpected issues. Older cars might be more sensitive, so doing it weekly is safer. Modern materials have improved durability, but don’t push it too far—like leaving it unused for a month increases risks. I set a weekly reminder on my phone and use the time to relax with music. In short, starting it more often saves money on replacement parts.

From my perspective, I prioritize both economy and environmental protection. Excessive idling of parked vehicles wastes fuel and increases emissions, but not starting the car at all is worse as it leads to component damage. A balanced approach is to start the engine and let it idle for about 10 minutes every 10 days. The fuel consumption is negligible, and on average, it saves hundreds of dollars annually on replacement costs. Environmentally speaking, it avoids the waste of producing new parts and results in lower carbon emissions. Personally, I've calculated that starting the car once every two weeks when it's idle is sufficient to maintain the battery and engine lubrication. In extreme cases, such as long-term travel, using a low-consumption charger or disconnecting the cables is even better, reducing idle pollution. It's both economical and green.

When I use my car infrequently, I find environmental factors are important. In cold or hot weather, the discharges quickly, so I recommend starting the car every 7 days and letting it idle for 15 minutes. This charges the battery while also lubricating the engine components. I set a weekend reminder on my phone, and when starting, I make a habit of pressing the accelerator slightly or moving the car a little to exercise the tires and suspension. In high-humidity areas, the risk of rust may be higher, so check the fluid levels. If parked for over a month, I disconnect the battery cable or use a maintenance tool, but weekly starts are the most convenient. To avoid embarrassing breakdowns, spending a few extra minutes starting the car ensures peace of mind and durability.
