How often should a parked vehicle be started?

It is recommended to start the car once a week and let it idle for a few minutes. The reasons are: 1. When a car is not started for a long time, most of the lubricating oil adhering to the parts that should be lubricated will flow to the oil pan due to gravity, reducing the lubrication effect on the moving parts. 2. When metal is not protected by an oil film, it easily reacts with oxygen to form an oxide film, increasing friction and making it difficult to start. 3. If the battery does not receive a charge for a long time, the sulfation process of the battery plates will intensify, increasing the internal resistance of the battery and reducing its lifespan. 4. Due to the self-discharge effect of the battery, the voltage will drop below 85%, making the battery irreparable.
I have extensive driving experience, and leaving a vehicle parked for too long can easily lead to problems. It's recommended to start the car at least every two weeks and let it run for 10 to 15 minutes. If left unused for an extended period, such as over a month, the battery will gradually discharge and eventually die, making it difficult to start and requiring you to spend money on a new battery or charging. Fluids will also settle and accumulate in the engine, leading to poor lubrication and part wear. Parking outdoors is even worse, as rodents and birds may chew on wires and damage the electrical system. Remember to drive a short distance after starting the car to keep the tires moving and prevent flat spots, and check if the brakes are rusty. I personally experienced leaving a car parked for three months without moving it, and the cost of replacing the tires was a painful lesson of over a thousand yuan. In short, regular starting and maintenance are low-cost, safe, and reliable. Don’t be lazy and risk bigger issues.
