The engine is the heart of the car, and the oil is the blood of the engine.
In addition to extending the life of the engine
It can also play a role in auxiliary cooling and cooling.
Sealing leak-proof, shock absorption and cushioning
Nowadays, more and more car owners realize the importance of engine oil,
But little is known about the proper use of motor oil.
Today, let's talk about some common engine oil misconceptions.
01. Do you need to change the oil as soon as the oil is dark?
Many times, we will notice that the oil of the engine turns black, well, a lot
Novice drivers feel that the oil can't be used because of their lack of experience, in fact
This method of judgment is very unprofessional.
Although engine oil is more susceptible to oxidation and deterioration when working at high temperatures,
But with the continuous improvement of lubricating oil quality, especially the use of multi-grade engine oil,
The oil will turn black faster, but that doesn't mean you have to change to a new one.
02. Do you only add or change the engine oil?
If you don't change the oil for a long time, the viscosity of the oil will decrease and it will not be good
The outer wall of the parts forms a layer of lubricating protective film, so the oil
When lubricity is reduced, it can lead to increased wear on the components.
When you only mix the new oil with the new oil and don't take the old one out, the oil is there
During use, the performance will gradually decline due to pollution, oxidation and other reasons.
At the same time, there will be some attrition.
03. How long does the oil with higher viscosity last?
Some car owners believe that the viscosity of engine oil will continue to decrease with the use of time, therefore
It is a misconception that the higher the viscosity of the oil, the longer it will last.
Because the use of engine oil is related to engine performance, the degree of wear, the driving environment and
Temperature is closely related, but also with its own quality level, wear resistance and high temperature resistance
Oxidation additives are closely related.
04. Would you rather add more oil than less?
The amount of oil is slightly lower than the scale on the dipstick, and too much oil will increase the rotational resistance of the crankshaft and reduce the engine's
output power, and those excess oil will enter the combustion chamber to participate in combustion, causing the vehicle to burn oil, blue smoke,
Fuel consumption has increased.
