What are the results of mixing car lubricants?

All kinds of automobile lubricating oil, its base oil in addition to the viscosity grade is different, the rest are the same, the difference only lies in the variety and number of its increased components. Therefore, lubricating oil varieties and quality grades are generally divided according to the variety and quantity of added components. Additives of different types of lubricating oil can not be mixed, otherwise it may make the additive in the oil attack chemical reaction, harm the due role of lubricating oil, may cause mechanical damage.

With the continuous improvement of additives and their formulations, some general oils have been developed and produced. 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, comprehensively compare the title, variety and trademark of oil, and choose and use grades and appropriate trademarks reasonably.
