What are the effects of not changing engine oil for a long time?

The effects of not changing engine oil for a long time: 1. It will cause the engine oil to become ineffective and deteriorate. Instead of providing protection, the oil will increase wear and damage to the mechanical parts; 2. The cooling effect will be reduced. The heat absorption and thermal conductivity of oil are far superior to water. If the oil deteriorates severely, the heat dissipation function will be greatly reduced; 3. Once the oil deteriorates and its performance declines, the lubrication performance of the bearings and the lubrication and cooling function of the mechanical transmission components will be lost, further damaging the engine. The harm is similar to that of insufficient oil. Insufficient oil causes direct damage, while not changing the oil depends on whether the oil has deteriorated and its performance has declined. Damage occurs only after deterioration and performance decline, and the process is relatively longer, causing gradual damage; 4. If the engine oil is not changed for a long time and only topped up when low, it will inevitably lead to a large amount of carbon deposits and sludge accumulation. These impurities will not only affect heat dissipation and lubrication but may also severely clog the oil passages, leading to engine damage or even complete failure.
