How often should you at least drive a car that's been sitting idle?

If it's a new car, you should drive it at least once a month. Here is relevant information about car storage methods: 1. For long-term parking, it's best to keep the car in a garage: The car's paint is like human clothing. The first priority when storing a vehicle for extended periods is protecting the paint surface, as fallen leaves, dust, and even rain or snow can damage the paint. During holidays, fireworks can easily hit the paint surface, exposing the metal body and easily causing rust. 2. Appropriately increase tire pressure: After a vehicle sits idle for an extended period, the four tires' contact points are prone to pressure-induced deformation. The longer the parking duration, the harder it is for the deformed areas to recover, eventually rendering the tires unusable. If not replaced promptly, driving at high speeds can cause body vibrations, creating driving hazards.

I remember driving for decades, and cars need to be driven regularly when parked, otherwise they develop problems. The battery is the biggest issue; leaving it unused for a week or two can easily drain it, making it difficult to start. If parked for too long, tires can deform under pressure, making driving unstable and potentially leading to blowouts. Engine oil that doesn’t circulate can settle and deteriorate, reducing lubrication effectiveness and causing internal wear. Once, I was away on a business trip for three months, and when I returned, the car wouldn’t start. In the end, I had to replace the battery and clean the engine system, costing me a lot of unnecessary money. My advice is to drive the car at least every two weeks, for about 20-30 minutes each time, to recharge the battery, keep the mechanical parts active, and extend the car’s lifespan—saving money and giving peace of mind.

I usually worry about safety, and leaving a car parked for too long poses significant risks. Tires under prolonged heavy pressure can permanently deform, making the car prone to imbalance and accidents when driven. Brake discs rust in humid weather or garages, causing grinding noises or even failure during braking, especially in rainy conditions. Without engine operation, lubrication becomes insufficient, leading to increased wear during startup. I recommend starting the car every week or two, even for a short trip to the supermarket, to prevent these issues. I once left my car unused for two months, and when I drove it, I heard a screeching sound and nearly had an accident. Regularly driving for just ten minutes is a simple way to maintain the car and ensure safety.

I know a bit about car conditions. From a component perspective, when a car sits idle, the engine oil drains back, leaving lubrication points dry and prone to rust; fuel lines accumulate sediment, potentially clogging injectors; the battery self-discharges quickly, draining within weeks and causing startup failure. All these accelerate aging. I recommend starting the engine once a month and driving for at least half an hour to recharge and maintain the system, which can avoid major repair troubles.

I live in the city and often park my car in the garage. I drive it once a month to prevent any unexpected issues. A friend of mine left his car parked for two months without moving it, and the battery died, requiring replacement, along with new tires, costing thousands in repairs. A stationary car deteriorates quickly—engine oil and fluids degrade, and the battery drains faster. Taking short drives not only recharges the battery but also keeps the mechanical parts active, saving both hassle and money. Routine maintenance isn’t difficult.

Calculating the economic costs, leaving a car unused for long periods actually costs more money. A new battery can cost hundreds to thousands, and replacing deformed tires is another expense; engines that aren't run regularly are prone to damage, and repairs can be even more expensive. Driving the car once every one to three weeks for about twenty minutes each time helps recharge the battery and prevent depletion, especially in winter when more frequent use is needed to prevent battery wear. In the long run, this saves on repair costs and makes maintenance simpler and more efficient.
