What happens if a car is not maintained for a long time?

[Tom]

Consequences of long-term lack of car maintenance: 1. The car paint is prone to damage, especially in summer when the weather is hot, and UV rays can corrode the car paint, making the car look old quickly; 2. If the air filter exceeds its replacement range, it will lose its ability to filter air impurities, failing to protect the engine's internal pistons, intake and exhaust valves, piston rings, and cylinders; 3. Tires will age faster, and in severe cases, may lose air or become unusable; 4. If the car is left unused for a long time, the oxidation of engine oil will be more severe than during normal driving. Oxidized oil has reduced lubrication effectiveness, failing to protect the engine, and certain acidic substances in the oil can corrode engine components, affecting the engine's normal operation.
