Oil is originally in a liquid state, but after emulsification, it can condense at the oil filler cap. In recent years, reports of oil emulsification have suddenly become frequent, affecting many well-known brands such as Honda, Changan, and Toyota. Oil is like the "blood" of the engine, but once it becomes emulsified, it looks like it has "leukemia." So, how does an engine get such a "serious illness"?

"Causes of Oil Emulsification"
Essentially, oil emulsification occurs when oil mixes with water, creating a white, milky substance. One might wonder, isn't the engine sealed? How does water get mixed with the oil?
Clearly, there must be an issue in some part of the engine, leading to a problem with the seal quality. This allows coolant or external moisture to enter, causing emulsification.
"Is Oil Emulsification Really That Serious?"
If you notice that the oil on the dipstick has turned white, it means that emulsification has already occurred within the engine compartment, and the oil has even deteriorated. This situation is much more serious than simple emulsification at the oil filler cap.
If oil emulsification is only found at the oil filler cap, this phenomenon is easier to understand. It's similar to how windows fog up in environments with significant temperature differences between the inside and outside. The emulsification on the oil cap is the same principle.
Fortunately, most reports from car owners about oil emulsification are related to the presence of emulsified substances at the oil filler cap. This phenomenon is particularly noticeable in winter and, although not entirely without issues, it is more like a "chronic illness" that, if left unchecked, may affect engine performance over time.
"How to Avoid Oil Emulsification?"
1:Change driving habits by taking longer trips and reducing the number of short-distance drives.
2:Choose higher-quality oil products.
3:In low-temperature environments, it is best to warm up the car for a period before driving.
4:Increase the frequency of maintenance and shorten the intervals between services.
