Frequent use of good oil will have what effect on the car engine?

What is the effect of regular use of good motor oil on the car engine?4S store teacher to tell the truth! Most people don't know much about motor oil because one is too specialized and the other is too troublesome. “Anyway, the money is not much, change a similar, will not have any problems on the line” This is the mentality of most car owners, so they prefer to choose the car manual (handbook) or the store staff's recommendations.

Oil, that is, engine lubricants, known as the car's “blood”, the engine can play a lubricating, cleaning, cooling, sealing, wear reduction, rust, corrosion and other roles. Engine is the heart of the car, the engine has a lot of mutual friction movement of the metal surface, these parts of the movement of fast, poor environment, working temperature up to 400 ° C to 600 ° C. In such poor working conditions, only qualified lubricating oil can reduce the wear and tear of the engine parts, to extend the service life.

The function of the oil: 1, lubrication 2, cooling 3, cleaning 4, sealing, 5, rust.

Oil composition: 1, base oil 2, additives. The base oil accounts for about 95%, the good or bad of the oil product depends largely on the good or bad of the base oil used. Additives are: viscosity index improver, cleaning and dispersing agent, anti-wear agent, antioxidant, coagulant reducer friction improver, rust inhibitor, anti-foam agent and so on.

Engine oil through the formation of oil film lubrication, so that the dry friction of the metal into the liquid friction between the oil layer, reduce frictional resistance, reduce wear and tear of machine parts. At the same time, the oil also plays the role of cooling, cleaning, sealing, rust prevention and elimination of shock loads.

In general, the oil is replaced when you do maintenance on your car, such as 7500 kilometers a maintenance. Most people are to drive the car to the 4S store, they do not have to care, the store directly to the change (original original), or the store gives a certain range of options, the owner of the car in this range to choose a their own want and then replaced.

For the new engine, should not use too good full synthetic oil, because the new engine still need to break in, at this time if the use of too good oil, the oil itself to form a protective film will be a certain degree on the break-in process to produce obstacles, which may affect the engine.

For the old engine, long time use of good engine oil, can to a certain extent reduce the engine noise, wear and tear. After all, the comparative effect from the basic friction experiment is obvious, in fact, some owners feel that the sound has become smaller after replacing the good engine oil, it should not be an illusion.
