In order to improve the application period of vehicles, make full use of vehicles in LanzhouLubricating oilThe role of, and pay attention to the use of engine oil selection?。However, some car buyers often have some misunderstandings when applying lubricating oil, causing harm。Some car buyers feel the higher the price of crude oil, so the use of synthetic oil in domestic cars, especially new cars。As we all know, this is generally not worth the harm and many disadvantages will occur。The more expensive ones are not always good。

      If you blindly follow the trend of using more expensive oil, because the engine is thin at the normal working temperature, the air pressure will be very low, and even cannot reach the specified working pressure, and normal lubrication can not be achieved。Increase engine wear rate。Engine oil operates under harsh high temperature specifications, which is conducive to oxidation and mold, resulting in lubrication damage。Therefore, after a period of use, the oil will generally become moldy and lack proper lubrication。However, I do not know that with the continuous improvement of the quality of automotive lubricating oil, especially the use of heavy oil, the blackening of oil does not necessarily mean that the oil has long been degraded。

       Therefore, whether it is deteriorating or not, a variety of indicators should be tested, and oil should be changed on time to reduce cost。The quality of the lubricant is immediately related to the length of the engine's service life。New cars have strict requirements for lubricating oil。What kind of oil？How to disassemble it should be carried out in accordance with the regulations of the automobile lubricant manufacturer。When selecting lubricants, pay attention to the quality level and viscosity level。Should be based on engine compression ratio?Offset selection feature level。And then depending on the temperature?Load selection viscosity level。High quality oil ensures engine lubrication。Reduce damage?Reduce the frequency and ease of maintenance。When selecting the viscosity of the oil, try to use low-viscosity oil to save fuel in engine lubrication and tightness。Multi-viscosity automotive lubricants have the characteristics of light oil at low temperatures and light fuel oil at high temperatures。In cases where multi-grade oils are highly recommended, multi-grade oils can replace a wide variety of single-grade oils。While multi-grade oils can be used for cold and warm seasons and heavy engine oils, single-viscosity lubricants are generally recommended to help lubricate the engine and improve engine life。Therefore, it is not necessary to feel the use of multi-viscosity lubricants。Lanzhou Liulian lubricant factory is committed to the research and development of metal processing oil,Hydraulic oilOil production and application。
