Motor oil is the blood that maintains the engine's life. It is a component that is capable of cooling and lubricating the engine. Now, more and more owners are aware of the importance of the oil, but the correct use of the oil is poorly understood.

One, when the oil change

People often say: the car should be regular oil change. But how long in the end for a regular? Basically, every car's manual will be clearly written. In the past, the standard is every 5000 kilometers, but in recent years, the automobile manufacturers continue to develop research, hope that the structure of the engine can be improved, the need for regular maintenance and oil change time. So, many new cars in general driving situations, if the use of synthetic oil, basically can be replaced once every 10 thousand km oil, some can even drag on 20 thousand km. Automobile maintenance professionals believe that the "driving" is often traveling on the highway, rarely stop and go. But if often in city driving, go to where there are traffic lights, real traffic congestion and each trip away most and not more than ten kilometers. This driving method belongs to "wear and tear of driving.

In the "loss of driving conditions, engine wear is relatively large, the oil demand is relatively high. Therefore, it is recommended to shorten the interval between the replacement of oil, to effectively protect the engine.

Tip: peacetime, we very difficult by the naked eye or touch to determine oil is not the change, but after long-term use, oil impurities accumulate, if not timely replacement of the new oil, these impurities for a long time will wear engine, shorten the car's life.

Two, choose how to choose oil

Choice of good oil, can make the car more durable, more dynamic. Good oil, especially the total synthesis of oil in addition to protect the engine, oil to reduce the number of, also can reduce the cost of gasoline. So, it is more than two times the price of ordinary oil, is the best choice for many owners.

Purchase oil attention four elements

Under normal circumstances, the choice of motor oil should pay attention to the following four elements:

1, the choice of oil should be based on the requirements of the engine to choose, it is not necessary to use a lower engine on the use of too high level of oil, it can not lower the use of oil in the higher requirements of the engine.

2, should be as far as possible to choose a multi-stage oil, multi-level oil due to savings, long life, high efficiency, the engine has a better protective effect. Based on the characteristics of multi-stage oil, in the use of the process may be too early onset of black, oil pressure than ordinary oil small phenomenon, are normal.

3, some domestic brands of oil quality is quite good, and the price is lower than similar imported products many, ease of use, there is no need to blindly pursuit "kerosene".

4, such as the engine is in good condition, and the seasonal temperature is low, should be used as much as possible viscosity of the smaller oil, so as to make the flow of oil. In the case of high temperature season or serious wear of the engine, the choice of high viscosity of the oil is conducive to the formation of oil film, reduce engine wear.

Tip: the market brand of oil, to select the level of oil, although expensive, but for the protection of engine parts will is better.

Three, the amount of oil should be slightly lower than the scale of oil

As we all know, oil for engine movement is really important, because it is responsible for two major functions of lubrication and heat. Therefore, at any time, for the engine, never lack of oil. But too much to add (more than the upper limit of the scale) has a bad effect on the outcome. Too much oil, will increase the crankshaft rotational resistance, reduce the output power of the engine, and the excess oil will fleeing into the combustion chamber and combust, causing the vehicle to burn engine oil, take the blue smoke with increasing even fuel consumption. After the combustion of oil residue (the main component is carbon, very hard) will accumulate in the wall of the combustion chamber, reduce the space of the combustion chamber, so as to reduce the engine's compression ratio, at the same time, also can accelerate the cylinder and the piston wear and reduce the service life of the vehicle.

In the addition of lubricating oil, be sure to keep the scale is slightly lower than the oil. In addition to master the oil model, season, climate, engine displacement, technical performance, and many other factors. Therefore, it is best to choose a professional car care center, after the careful judgment of the car, select the applicable oil, and in the maintenance process carefully to prevent the hidden dangers. Of course, the general car maintenance center maintenance oil will not add more (cost control), but if it is your own oil, car maintenance center will not be too concerned about, then you have to pay attention to do not add oil.

Tip: add oil is a mistake, if found oil has more, the best car maintenance center entrusted to let go.
