What Are the Hazards of Leaving a Car Unused for a Long Time?

[DiAbigail]

Here are the hazards of leaving a car unused for a long time: 1. Accelerated engine wear: When a vehicle remains parked for an extended period, the lubricating oil film on the surfaces of the engine cylinders and pistons can deteriorate due to exposure to oxygen and other corrosive acidic and alkaline components in the air. This forms a gummy substance that loses its lubricating properties. Upon restarting the engine, dry or semi-dry friction occurs between the cylinders and pistons, accelerating component wear. Additionally, the starting resistance significantly increases, making it difficult to start the engine. 2. Tire deformation: When a car is parked, its weight is borne by the parts of the four tires in contact with the ground, causing these contact areas to compress and deform. The longer the car remains unused, the harder it is for the deformed areas to recover, altering the mass distribution around the tires and resulting in uneven rolling radii. This imbalance can cause body vibrations during high-speed driving, affecting ride comfort, accelerating tire wear, and introducing safety risks.
