What are the misunderstandings in the use of automotive lubricants?
- 2018-10-08-

Automotive lubricants are used at very high frequency during maintenance. In addition to protecting the starter and reducing the number of oil changes, high-quality lubricants can also reduce the cost of gasoline. At the same time, we must also pay attention to not causing car problems due to the improper use of smooth oil. The " inappropriate " application method is generally due to the four " misunderstandings " of the riders on smooth oil .


For the following four " misunderstandings " , Shanghai Zhuoli Luluene Co., Ltd. answers us:

Misunderstanding 1: Lubricants are often added without changing

Lubricating oil should be checked frequently, but only the amount of oil that is not compensated for replacement is not enough, but the loss of lubricating oil function cannot be fully compensated. In the process of using the lubricating oil, the quality will gradually drop due to pollution, oxidation, etc., and there will be some cost, which will reduce the number.


Misunderstanding 2: The use of additives is large

The truly high-quality lubricants are products with a variety of initiator protection functions. The formula already contains a variety of additives, including anti-wear agents, and the balance of lubricants is carefully formulated to ensure the full development of various functions. Adding other additives by yourself can not only bring the rated protection to the vehicle, but it is easy to react with the chemical substances in the oil to form the landing of the comprehensive function of the oil.


Misunderstanding 3: When the lubricant turns black, it is time to change the oil.

This understanding is not comprehensive. Regarding the smooth oil without the anti-scrapping agent, the blackening of the color is indeed an indication that the oil has been severely deteriorated, but the smooth oil used in modern automobiles is generally provided with a bismuth disintegrating agent. The tincture cleans the adhesive film adhered to the piston and the black carbon deposit, and is evacuated in the oil to reduce the formation of high temperature precipitates of the initiator. Therefore, the color of the smooth oil is easily blackened after a period of use, but this time The oil has not completely deteriorated.


Misunderstanding 4: Lubricating oil can add more

The amount of lubricant should be controlled between the upper and lower scale lines of the dipstick. As a result of too much lubricating oil, it will enter the combustion chamber from the gap between the cylinder and the piston to form a carbon deposit. These carbon deposits will improve the tightening ratio of the initiator and add the bias of the knocking; the red hot form of the carbon deposit in the cylinder is also prone to premature combustion. If it falls into the cylinder, it will aggravate the wear of the cylinder and the piston, and accelerate the pollution of the smooth oil. . Secondly, too much smooth oil adds the stirring resistance of the crankshaft connecting rod, which increases the fuel consumption.
