The engine oil is equivalent to the "blood" in the automobile engine. It flows between the engine parts and plays a lubricating role to prevent serious wear between parts.
In addition to the lubrication function, there are some other functions. Such as cooling, cleaning, sealing and leakage prevention, rust prevention and corrosion prevention, shock absorption and buffering.
Changing oil is one of the most routine maintenance items in automobile maintenance. In addition to protecting the engine and reducing the number of oil changes, high-quality oil can also save fuel consumption. However, many people have some misunderstandings about the use of engine oil. If they do not pay attention to it, it may seriously affect the service life of the car!

01. The engine oil must be replaced when it becomes black
The blackened oil does not mean that it has deteriorated. The quality of the genuine brand oil sold on the market is quite high and can maintain the lubricating function under high temperature conditions.
Generally speaking, the oil has the function of cleaning and dispersing. After adding new oil, the sludge and carbon deposits on the parts are dispersed in the oil, which will lead to the black color of the oil after a certain time. The oil color, viscosity, etc. should be checked to determine whether it needs to be replaced by checking whether it is deteriorated, rather than observing that the oil color is black.
02. The role of oil additives is large
At present, there are various oil additives on the market, which all claim to effectively reduce the wear of machine parts and reduce fuel consumption. Oil additives cannot be added randomly. There may be incompatibility or chemical reaction between oil and additives. If the owner adds inappropriate additives to the engine oil, it will cause changes in the lubricating properties of the engine oil, which will not only reduce the wear of the parts, but also cause more serious damage to the vehicle.

03. Do not add less or more oil
The oil quantity should be controlled between the upper and lower scale lines of the oil dipstick. Because too much oil will flow from the gap between the cylinder and the piston into the combustion chamber and form carbon deposits. These deposits will increase the compression ratio of the engine and increase the probability of detonation.
Secondly, too much oil increases the stirring resistance of the crankshaft connecting rod and increases fuel consumption.
In addition, adding more oil will increase the internal pressure of the engine and easily lead to oil leakage of the engine seals.
04. The higher/lower the oil viscosity, the better
Some car owners think that adding high viscosity lubricating oil can protect the engine, and that using low viscosity oil can save fuel. These ideas are all mistaken. In order to prevent the friction of internal parts of the engine, the oil must have sufficient viscosity, otherwise it cannot form sufficient oil film protection at the operating temperature. However, the use of oil with excessive viscosity will lead to slow internal flow, increased resistance, increased fuel consumption and reduced engine power output.
The use of oil with low viscosity can guarantee the fluidity, but it is difficult to form a good oil film protection at the operating temperature, which will cause damage to the engine and power loss. Therefore, only by using the oil viscosity correctly can the vehicle reach the best state
05. The engine oil is only added but not changed
If the engine oil is not changed for a long time, the protective ability of the engine oil will be reduced, and the outer wall of the parts will not be well protected by a layer of lubricating protective film. Once the lubricating ability of the engine oil is reduced, the wear of the parts will be aggravated directly. Only adding and not changing the oil can only make up for the shortage of oil quantity, and can not completely compensate for the loss of lubricating oil performance.
