Why cant car oils be mixed

There are still many kinds of car lubricating oil products on the market, and owners can try many brands of goods. But the exception is oil, there is still a big difference between different types. The formula of different brands of smooth oil must be different. So why can't car oils be mixed?

All kinds of automobile lubricating oil, its base oil in addition to the viscosity grade is different, the other is the same, the difference only lies in the variety and number of its added ingredients. Therefore, lubricating oil varieties and quality grades are generally divided according to the variety and quantity of added ingredients. Different kinds of lubricating oil additives can not be mixed, otherwise it can make the additives in the oil attack chemical reaction, harm the due role of lubricating oil, may cause damage to the machine. With the constant improvement of additives and their formulations, some general oils have been developed and consumed. For example, gasoline and diesel engines with QE/CC, QF/CD lubricating oil. They can be used in the range of marked grades. Therefore, whether lubricating oil can be mixed should be based on the requirements of the manual, one-sided control of the title, variety and trademark of oil, and reasonable selection and use of grades and appropriate trademarks.



The same type of oil goods, will also distinguish between different viscosity grades. Oil oil also clearly remember before a pro said: "I think the 40 viscosity of the oil is a little thick, 30 of the oil is a little thin, I prepare to mix them in a reuse, 35 viscosity should be just good!" I just want to say: "dear, I know you are good at math, but the viscosity is not so calculated." This and the freezing point results of antifreeze is the same truth, high freezing point and low freezing point antifreeze mixture, freezing point thought will lose the average.
