Automobile oil is used very frequently in maintenance. In addition to protecting the engine and reducing the number of oil change, premium lubricants also save fuel on gasoline. At the same time, it should also be careful not to cause automobile trouble due to improper use of lubricating oil. "Improper" method of use generally comes from the Four Misunderstandings of lubricating oil".

For the following four kinds of "misunderstanding", Taizhou Rong big, Beijing Great Automotive Components Company Limited gave a professional explanation:

Myth 1: lubricants are often added

It is correct to check the lubricating oil regularly, but only replace and replace, which can only compensate for the shortage of oil quantity, but can not fully compensate for the loss of lubricating oil performance. In the use of lubricating oil, due to pollution, oxidation and other reasons, the quality will gradually decline, while there will be some consumption, so that the number of reduced.

Myth two: additives are of great use

The real oil quality is have a variety of function of motor protection products, a variety of additives containing formulations, including antiwear agent, lubricating oil and give full play to the most exquisite formula to ensure balanced performance. Self addition of other additives can not only bring additional protection to the vehicle, but also react with the chemicals in the oil, resulting in a decline in the overall performance of the engine oil.

Myth three: when the oil is black, it's time to change the oil

This understanding is not comprehensive. For no added dispersion of lubricants, the black color is indeed a serious deterioration of oil performance, but the use of modern automotive lubricants are generally accompanied by a quiet decomposition agent. This quiet agent will adhere to the piston glue film and carbon black washed down, and dispersed in oil, reduce the engine high temperature deposits, so the use of lubricating oil after a period of time to color black, but the oil is not completely bad.

Misunderstanding four: lubricating oil can add more

The amount of grease should be kept between the upper and lower scales of the oil dipstick. Because the lubricant is too much, it will break into the combustion chamber from the gap between the cylinder and the piston to form a coke. These deposits will increase the compression ratio of the engine, increase the tendency to produce knock; coke in the cylinder are red state but also easy to cause early burning, such as falling into the cylinder will aggravate the wear of the cylinder and piston, will accelerate oil pollution. Secondly, the lubricating oil is too much, which increases the resistance of the crankshaft connecting rod and increases the fuel consumption.
