Often to change the oil maintenance, but have what misunderstanding? No matter what the industry, he is most likely to repeat? Do you often do maintenance at the same store, what people say what you believe, do not doubt, you do not pit pit who? Maintenance of such a thing,often changing place. ~ trouble is really in trouble, but better than the slaughter! Prefer to trouble spots, can not bear to send silver.

Automobile lubricating oil used in the repair and maintenance of very high frequency. High quality lubricating oil in addition to engine protection, reduce the number of oil, but also can savefuel costs. But if the improper use of lubricating oil, is the cause of fault! Since the landlordasked today, it is about the general enthusiasm on the Four Misunderstandings in used lubricating oils!

Lubricating oil is black, the oil change?

This is your problem. Some friends think: the realization of oil color black is a serious deterioration of the oil, it would have to change. In fact, this is only for the lubricating oil is notquiet dispersant, but oil modern vehicles are usually added quiet dispersant. This quiet agent willadhere to the piston on the film and black carbon washing down, and dispersed in the oil,thereby reducing the generation engine high temperature deposits, so the color to use for a period of time after the oil is easy to become black, but this does not mean that the product has been deteriorating.

The teacher often encourage maintenance shop landlord for lubricating oil, but he is notprofessional, not aware of this, or is the pit lord, want to make more money. This kind of "slaughter", that landlord still dare to?

Lubricants often add do not change?

Just said, there is lubricating oil detergent dispersant and black is normal, do not change, butcan not always only and does not change! Just not only make up for lack of oil change quantity,but not fully compensate the loss of performance of lubricating oil. You should know, the lubricating oil in use process, due to pollution, oxidation and other reasons is worse, at the same time, there will be some consumption, to reduce the number of. In order to make the oil well, after a period of time or need to be replaced.

Sometimes additives is the most useful

Some friends said, adding the additive in lubricating oil, can play a better role. Here, you canresponsibly tell you, this is a misunderstanding! Lubricating oil quality is really have a variety offunction of motor protection products, a variety of additives containing formulations, includinganti-wear agent, give full play to the most exquisite and lubricant formulation in order to protect the various properties of the equilibrium.

Add the other additives not only to the vehicle additional protection, chemical and oil instead ofin the reaction, resulting in poor performance of oil. It is not superfluous?

Oil will be more and more?

Some friends think, the lubricating oil can more is more, seemed to be less will suffer, every timeto fill. Oh ~ I can not open! Tell the landlord, oil amount should be controlled between oil ruler,scale line as well. Because too much oil from the gap between the piston and cylinder in fleeing into the combustion chamber to form coke.

Carbon deposition is not what good stuff! These carbon will improve the compression ratio of the engine, increase the tendency to produce knock; coke formation in the cylinder are red state but also easy to cause the early burning, if you fall into the cylinder will aggravate the wear of cylinder and piston, will accelerate oil pollution.
