In the daily communication of car owners, engine oil is often referred to as the "liquid of life" of automobiles. Many veteran drivers will feel that the money is well spent when they see the oil turn black like ink when they change the oil, because it shows that the oil has effectively cleaned the engine and removed impurities from the inside of the engine. However, for a four-year-old car owner, his experience was a little different.

The owner found that every time the oil was changed, the color of the oil was not as pitch black as other owners had described. At first, he was secretly glad that his engine was in good shape, but as time went on, the unusual phenomenon made him suspicious. To solve this mystery, he began to delve into the possible reasons why the oil did not black.

After some investigation, he first ruled out the possibility that the driving environment was too superior. Although most of his daily routes are in areas with good road conditions and relatively clean air, they do not reach the extreme level of cleanliness, so this factor does not seem to be enough to explain the fact that the oil is not black.

He then turned his attention to the vehicle's engine technology. By consulting relevant materials, he found that modern engines use high-precision manufacturing processes and advanced fuel injection technology, which allows fuel to burn more fully and reduce the generation of carbon deposits and impurities. At the same time, the sealing performance of the engine has been significantly improved, reducing the amount of oil entering the combustion chamber and participating in combustion. These technical characteristics may be an important reason why his oil is not black.

However, it's not entirely good that the oil isn't black. In addition to lubrication, motor oil also serves multiple functions such as cleaning, heat dissipation and sealing. Under normal conditions, the oil circulates through the engine, absorbing impurities such as metal debris, dust and carbon deposits, and gradually turning black. If the oil remains dark for a long time, it may mean that its cleaning ability is not being fully utilized, which may adversely affect the life of the engine in the long run.

This discovery made car owners pay more attention to the details of car maintenance. During a maintenance process, the maintenance master also mentioned this problem and suggested that he appropriately shorten the oil change interval. Although the oil does not look dark, the additive components in it may have been depleted and can no longer provide full protection for the engine. Car owners are deeply aware of the importance of this advice, after all, the engine is the "heart" of the car, and maintenance work should not be sloppy.

Since then, owners have not only changed the oil regularly, but also started checking key components such as air filters and fuel filters to ensure that the air and fuel entering the engine are clean. At the same time, he also pays more attention to the key parameters such as water temperature and oil pressure of the engine, and immediately goes to a professional repair shop for inspection and repair once he finds any abnormalities.

Four years of car experience has made this car owner deeply realize that car maintenance cannot only look at the superficial phenomenon. Only by understanding the reasons and mechanisms behind it can we better protect your car and extend its service life. Today, he has become a car maintenance expert in his circle of friends, often sharing his maintenance experience with friends.
