Always go to maintain, but change the oil to have what mistake? No matter what the industry, the most easy to kill is familiar? You often do in the same shop to do maintenance, people say what you believe in what you do, and do not doubt, do not pit you pit who? Maintenance of this kind of thing, or often change place. Is really ~ trouble trouble, but better than the slaughter! Would rather trouble point, but also reluctant to send money to send.

The frequency of the use of motor oil in maintenance and maintenance is very high. High quality lubricating oil in addition to engine protection, reduce the number of oil, but also can save the cost of gasoline. But if the use of lubricating oil is not used, it will cause the car trouble yo! Since this landlord asked, it is about the general riders on four errors of lubricating oil used!

Lubricating oil black, should change?

Some of the friends of the basin that: the color of the oil is black oil is a serious deterioration of the liquid, then you have to change. In fact, this is only for the lack of a quiet dispersant of the lubricating oil, but the use of modern automotive lubricants generally have a quiet decomposition agent. This quiet agent will adhesion on the piston glue film and black carbon washing down, and dispersed in the oil, thereby reducing the generation of the sediment in the engine high temperature, lubricating oil for a period of time after the color to black, but this does not mean that the oil had deteriorated.

Shop maintenance master often cuanduo landlord for lubricating oil, if it were not for his lack of expertise, failed to recognize this, or is the pit lord, want to earn more money. This "black", the landlord later dare to go?

Often do not have to change the lubricating oil?

Just said, a lubricating oil cleaner decomposition agent black is normal, do not change, can not always only and does not change! Only to make up for the deficiency of the number of oil, but can not fully compensate for the loss of the performance of the lubricating oil. The landlord should know that the use of oil in the process, due to pollution, oxidation and other reasons, the quality will be poor, while there will be some consumption, so that the number of. In order to make the lubricating oil to give full play to its performance, the use of a period of time or need to be replaced.

Sometimes additives are useful

Some of the friends of the basin, in the lubricating oil to add additives, can play a better role. Here, you can tell the landlord, this understanding is wrong! The real high quality of the lubricating oil is a variety of engine protection functions of the finished product, the formula has contained a variety of additives, including anti - wear agent, and the most exquisite formula of lubricant to ensure the full play of all kinds of performance.

The addition of other additives can not only bring additional protection to the vehicle, but it is easy to react with the chemical substances in the oil, resulting in poor oil performance. This is not superfluous?

How much oil can be added?

Some friends think, lubricating oil can more is more like, and less will suffer, every time to fill. Well, how can you not see that! Tell the landlord, the amount of oil should be controlled in the oil on the oil ruler, the scale line between good. Because too much oil from the gap between the piston and cylinder in fleeing into the combustion chamber to form coke.

Carbon is not a good thing! These carbon will improve the engine compression ratio, increase the knock tendency; coke in the cylinder was glowing red also easily lead to premature combustion, if fall into the cylinder exacerbate cylinder and piston wear, but also accelerate the oil pollution.
