Does a car need an oil change if it's parked for a long time?

Yes, a car needs an oil change if it's parked for a long time. Here are the hazards of not changing the oil: 1. Causes the oil to become ineffective and deteriorate: The oil not only fails to protect but also increases wear and damage to the components. 2. Accumulation of impurities in the oil over time: Such as metal shavings, which can lead to corrosion of internal components. 3. Damages the engine: Once the oil deteriorates and its performance declines, the lubrication properties for bearings and the cooling function for mechanical transmission parts will be lost, further damaging the engine. Lack of oil causes direct damage, whereas not changing the oil depends on whether the oil has deteriorated and its performance has declined. Damage occurs after deterioration and performance decline, and the process is relatively longer, causing gradual damage.
