How Long Can a Car Sit Without Being Driven Before It Gets Damaged?

Generally speaking, leaving a car undriven for over a month can start to have an impact, though the effects are minimal at this stage. However, once it exceeds three months, the impact becomes significantly more severe. If a car isn't started for a month, some mechanical components may be affected due to insufficient lubrication from the engine oil. Beyond three months, the engine oil can deteriorate due to oxidation, and certain parts may rust or corrode. Consumables like the battery, tires, and paint will also be affected to varying degrees. If a car is left unused for an extended period, the following measures should be taken: 1. Park the car in a garage if available; otherwise, find a safe, dry, and shaded spot to park and cover it with a car cover. 2. Disconnect the battery. Only the negative terminal needs to be disconnected. 3. Clean out all items from the interior, especially avoiding leaving snacks inside. 4. Maintain sufficient tire pressure.
As someone who drives frequently, I've noticed that if a car sits unused for more than two weeks, problems start to arise. Last time I was away on business for a month without touching my car, the battery was completely dead when I returned, making it difficult to even call for roadside assistance. The tires had also flattened and deformed, likely due to uneven pressure distribution over time, causing a bumpy ride. The engine had trouble starting, possibly because the oil had settled and failed to lubricate properly. Prolonged parking also caused the brake pads to rust, resulting in squeaky noises. For safety, I believe it's essential to start the car at least every two weeks, letting the engine warm up for about ten minutes or taking a short drive to keep the components active. If the car will be parked for an even longer period, such as several months, it's best to disconnect the battery terminals or use a battery maintainer to prevent further damage. Regular vehicle checks can save a lot of repair hassle and expenses.
