Audi experts tell you that poor lubrication is the main cause of the oil problem
1. Poor engine lubrication conditions: in many cases, due to the lubrication of lubricating oil, the working conditions of the engine are relatively poor, and it is easy to have large engine heat load and high temperature. If the oil level is not appropriate according to the requirements and good lubrication is not provided for the bearing bush, the abnormal wear of the bearing bush will occur, plus the failure of the bearing bush for a long time.
2. Oil viscosity is too large: the selection of normal oil is very important, but it is also necessary to pay attention to the selection of oil viscosity grade. If the oil viscosity is too large, it will lead to the oil fluidity, the heat axis Bush that cannot be taken away, and the temperature of bearing Bush will increase, but it will also increase the running resistance of the moving parts of the engine.
3. The viscosity of lubricating oil is too small: if the viscosity of oil is too small, the oil film is not easy to form during the running time of the engine. At this time, the alloy layer of the axle housing will accelerate the wear. When the wear reaches a certain degree, the ceramic tile of the engine will be caused.
4. Low oil pressure: if the engine oil pressure is too low, the flow between the crankshaft and the bearing shell will be reduced, and the normal lubricating film will not be formed, resulting in wear and even damage of the bearing shell. There are many reasons for the low oil pressure, such as low viscosity of oil, abnormal operation of oil pump will cause low oil pressure.
5. The poor quality oil filter and oil filter are also very important. The poor quality filter can not filter out the impurities well. The impurities in the oil are used. Some defects of the filter paper even appear, resulting in the filter closing, the oil impurities can not filter out the hair, resulting in the engine lubrication conditions, so the engine tile occurs.
