Always go to maintenance, but for oil there is a misunderstanding? No matter what the industry, is most likely to kill regulars? You often do maintenance in the same shop, people say what you believe in, do not doubt, do not hang 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 points, but also reluctant to send money to the outside.

Automotive lubricants in the maintenance of the frequency of use 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 improper use of lubricating oil, 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?

This is the landlord encountered the problem. Some friends of the basin that: the color of the lubricating oil is a serious deterioration of the oil is realized, it must change. In fact, this is only for the use of the lubricant is not added to the quiet dispersion agent, but the use of modern cars are generally add a quiet oil. 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?

Lubricating oil is often added to the need for change?

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

Sometimes the additive is useful.

Some friends think, in the lubricating oil to add additives, can play a better role. Here, you can be responsible for telling the landlord, this understanding is wrong! The real quality of lubricating oil with a variety of engine protection function of the finished product, the formulation already contain a variety of additives, including antiwear agent and lubricant most is fastidious about the balanced formula to ensure the full play of the various performance.

Adding other additives not only can not bring extra protection to the vehicle, but it is easy to react with the chemical substances in the oil, resulting in deterioration of the overall performance of the oil. This is not superfluous?

Oil can add more to add?

Some friends think that lubricating oil can more is more like, and less will suffer, every time to fill. Oh ~ how can not see it so! Tell the landlord, the amount of oil should be controlled in the oil on the scale, the lower the scale between the lines as well. Because too much oil from the gap between the piston and cylinder in fleeing into the combustion chamber to form coke.

It's not a good thing to accumulate carbon! 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.
