Introduction of BMW engine oil

It is a common problem for BMW to burn engine oil, and there are many reasons for burning engine oil. However, with the quality of BMW, the possibility of burning engine oil due to engine quality problems is extremely small, which is mainly caused by corrosion and aging of valve oil seal, crankshaft oil seal and oil seal between turbocharger and intake port.

Because oil seal is a rubber product, it is easy to age after being used for a long time. Coupled with the high temperature and high pressure of the engine, the oil seal ages faster, thus reducing the sealing performance, and the oil can easily penetrate into the cylinder to participate in combustion. However, if it is the problem of burning oil in the valve oil seal, then this problem is not big, but there will be blue smoke when the cold car starts, and the hot car will disappear. At this time, it needs to be solved in a professional repair shop or 4s shop, and a new oil seal can be replaced.
