What are the symptoms of oil emulsification?

[LaJune]

If the engine oil emulsifies, some white milky substance will appear on the engine oil filler cap, which is a symptom of oil emulsification. Oil emulsification is caused by water entering the engine oil. If the oil emulsifies, it needs to be replaced immediately, otherwise it will cause engine damage. Here are the hazards of oil emulsification: 1. When emulsified oil leaks water in places like the bearings of mechanical equipment, it can likely destroy the oil film. 2. The emulsified liquid contains liquid water, which stays on the surface of mechanical parts and can cause rusting of equipment components, affecting the normal operation of the unit. 3. Emulsified oil deposits in the lubrication system, affecting the normal circulation of the lubricating oil, leading to insufficient oil supply to mechanical equipment and causing mechanical failures. 4. If emulsified oil is not treated promptly with equipment like oil purifiers, it will accelerate the overall aging of the oil. At the same time, the aged oil will produce harmful substances such as naphthenic acid soap and colloids, further accelerating the emulsification of healthy oil. 5. After the car engine oil is emulsified, the lubricating effect of the engine oil is greatly reduced, increasing the friction coefficient among various mechanical equipment components. During the operation of mechanical equipment, bearings are highly likely to be damaged due to overheating.
