Oil emulsification refers to the mixing of water or other liquids into engine oil to form a milky white or yellow-brown foamy mixture. This phenomenon usually occurs in parts such as the oil cap, oil dipstick or oil pan.
| parts | Phenomenon description |
|---|---|
| oil cap | Milky white foam or paste appears |

| oil pan | The oil fluidity becomes poor and may be accompanied by sediments |
2. Main causes of engine oil emulsification
According to recent technical discussions and feedback from car owners, the main reasons for engine oil emulsification are as follows:
| Reason | Proportion | Description |
|---|---|---|
| short distance travel | 45% | The engine does not heat up sufficiently and the water cannot evaporate |
| cold climate | 30% | Low temperatures lead to increased condensation |
| Poor engine seal | 15% | Coolant seeps into the oil system |
| Oil quality issues | 10% | Inferior engine oil has poor anti-emulsification properties |
3. The impact of oil emulsification on the engine
Oil emulsification will reduce the lubricating properties of the oil and may cause the following problems:
1. Accelerate engine wear
2. Block oil lines and filters
3. Reduce heat dissipation efficiency
4. May cause more serious mechanical failure
It is worth noting that experts pointed out in recent discussions:A small amount of emulsification is normal under certain conditions., don’t panic too much.
4. How to prevent and deal with engine oil emulsification

|---|---|
| Avoid frequent short-distance driving | Change engine oil and oil filter |
| Regular high speed driving | Check engine sealing |
| Use engine oil of appropriate viscosity | Clean engine lubrication system |
| Maintain good driving habits | Check cooling system for leaks |
5. Oil emulsification situation of recent hot models
According to the popularity of forum discussions, the engine oil emulsification problem of the following models has received greater attention:
| Brand | car model | Discussion popularity |
|---|---|---|
| toyota | RAV4 hybrid | high |
| Honda | CR-V | in |
| Chang'an | CS75 PLUS | in |
| Volkswagen | Tiguan L | low |
6. Expert advice
1. After discovering the emulsification phenomenon, first check whether the oil level is normal.
2. If the oil cap is only slightly emulsified, you can first observe
3. If the oil dipstick shows emulsification or abnormal oil volume, it should be repaired immediately.
4. Pay special attention to how you use your vehicle in winter
7. Common misunderstandings among car owners
According to recent discussions, many car owners have misunderstandings about engine oil emulsification:
Misunderstanding 1: Thinking that a small amount of emulsification is an engine failure
Myth 2: Frequent oil changes can completely avoid emulsification
Myth 3: All brands of vehicles will have the same degree of emulsification
Summary
Engine oil emulsification has been a hot topic in the automotive field recently, but car owners don't need to worry too much. Understanding its causes and correct handling methods can effectively prevent and solve this problem. The most important thing is to develop good driving habits, check the condition of the vehicle regularly, and deal with problems in a timely manner if any problems are found.
