Automotive lubricants in the maintenance of the use of very high frequency. The aluminum forging said the high quality lubricating oil in addition to engine protection, reduce the number of oil, but also can save the cost of gasoline. At the same time, we have to be careful not to because of lubricating oil caused by improper use of auto fault, "improper use of" from general having four "misunderstanding of lubricating oil".

For the following four kinds of "misunderstanding", the aluminum forging offers professional explanation:

Misunderstanding 1: lubricating oil often do not have to change

Always check the oil is correct, but only the replacement can not only make up for the lack of oil quantity, but can not fully compensate for the loss of oil performance. Lubricating oil in the use of the process, due to pollution, oxidation and other reasons, the quality will gradually decline, while there will be some consumption, so that the reduction in the number of.

Misunderstanding two: additives useful

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. Adding other additives not only can not bring extra protection to the vehicle, but it is easy to react with the chemicals in the oil, resulting in a decline in the overall performance of the engine oil.

Myth three: what time should the lubricating oil black oil change

This understanding is not comprehensive. For the oil did not add quiet dispersant, the black color is indeed a serious deterioration of the performance of the oil, but the use of modern automotive lubricants generally have 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.

Myth four: lubricating oil can add more

The amount of lubricating oil should be controlled between the upper and lower scales of the oil dipstick. Because too much oil from the gap between the piston and cylinder in fleeing into the combustion chamber to form 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 increases the friction resistance of the crankshaft connecting rod, so that the fuel consumption increases.
