如何正确使用机油 润滑油使用的10个误区（10 misunderstandings on how to use the lubricating oil correctly） Lubricating oil is very important for the car, is also essential, but if not the proper use of oil, but will not bring good results, following a brief talk about some mistakes in the use of oil, in order to protect their own car. How to correctly use lubricating oil, many owners still exist a little misunderstanding, specifically summarized as follows: 1. domestic cars blindly use imported oil Some owners believe that imported oil must be better than domestic oil, so imported oil is used in domestic cars, especially new ones. As we all know, doing so often is not worth the candle, there will be many ills. For example, most of the imported oil viscosity is low, it can not meet the requirements of domestic cars on the viscosity of the oil. With a variety of domestic engine parts with thermal expansion coefficient and the clearance of imported cars is large, and most of the domestic car engine oil radiator device, if blindly imported oil, because of engine oil in normal working temperature under pressure too thin so low, even less than the required working pressure, can not meet the needs of normal lubrication, engine wear. 2. oil blackening is oil deterioration Engine oil is working in a demanding high temperature condition, easy to oxidize, deteriorate, produce acidic substances, and stack polymer deposits, so as to destroy lubrication. In addition, the burning of the exhaust gas into the crankcase will also cause deterioration of the engine oil. Therefore, after a certain period of time, the engine oil will usually blacken and lose its proper lubrication. But with the continuous improvement of the quality of lubricating oil, especially the promotion of thickening oil, oil black does not necessarily mean deterioration of the oil. This is because the cleaning agent added to the thickened oil will disperse the deposits on the machine and darken the oil color. Whether should be the in
