With the arrival of winter and cold spells, car owners in some areas found a layer of white foamy liquid inside the sealing cap of the fuel filler, which is called "oil emulsification". Many car owners have questions about this, is engine oil emulsification a common problem in winter?How can we avoid oil emulsification?
First, we need to clarify the definition of oil emulsification. Oil emulsification refers to the phenomenon of emulsification caused by the mixing of two incompatible liquids, i.e. the oil turns milky white and creamy yellow, giving it a yogurt-like appearance, and foam may also appear on the upper layer. This phenomenon occurs due to the presence of insoluble substances in the mixture of the two liquids, which reduces the surface tension of the liquid and forms emulsification.
In winter, the oil is more prone to emulsification. This is due to the interaction between the hot air generated during engine operation and the external low temperature, which causes easily emulsified parts such as oil filler pipes and cylinder head covers to condense into small droplets when cooled. At the same time, the oil droplets also "slide" out of the engine and mix well with these small droplets, resulting in oil emulsification. This phenomenon is normal, but regular checks and oil changes are required to ensure the proper functioning of the engine.
We can see that the possible causes of oil emulsification mainly include:
1.The engine heats up too slowly, causing the water vapor in the oil to not evaporate, resulting in emulsification. This phenomenon often occurs in hybrid models, which rely on electric start, and the engine heats up slowly, making it more likely to cause this problem.
2.If you don't change the oil for a long time, it will cause the oil to deteriorate, and driving for a long time in extreme environments, or the driver's incorrect driving habits can also easily lead to oil emulsification.
3.The oil used is of poor quality and contains moisture, or the quality does not meet national standards.
So how do you avoid oil emulsification?First of all, it must be warmed up thoroughly. Before driving in winter, before driving on the road, the vehicle needs to be thoroughly heated to reduce the condensation of water vapor on the cylinder walls. It is recommended to warm up the vehicle within 30 seconds to 1 minute after the engine starts;Secondly, it is necessary to avoid frequent short drives. Without sufficient driving distance and running time, the moisture entering the engine cannot evaporate completely, which can easily lead to oil emulsification. The most important thing is to choose the right oil, and when changing the oil, you need to choose the right type of oil according to external factors such as actual location and temperature.
When it comes to choosing a motor oil, Wells lubricants are a great choice.
