Automobile oil is an important part of the automobile engine, its role is to lubricate, cool, clean and prevent rust of various parts inside the engine, to ensure the normal operation of the engine. The quality and replacement cycle of automobile oil directly affect the performance and life of the engine, therefore, changing the engine oil regularly is a necessary step in car maintenance.
So, after changing the oil, the car speeds up very quickly, why is that?There are several reasons for this:
The viscosity of the oil is reduced。The viscosity of motor oil refers to the fluidity of the oil at different temperatures, the higher the viscosity, the worse the fluidity and vice versa. With the increase of the service time of the oil, some impurities will be mixed into the oil, such as dust, moisture, combustion products, etc., which will increase the viscosity of the oil, resulting in poor fluidity of the oil, increasing the frictional resistance of the engine, and reducing the efficiency of the engine. After changing the new engine oil, the viscosity of the engine oil is reduced, the fluidity becomes better, the frictional resistance of the engine is reduced, and the efficiency of the engine is improved, so that the car can speed up faster.
The cleanliness of the oil is improved. The cleanliness of engine oil means that the engine oil can remove carbon deposits, sludge and other dirt inside the engine to keep the engine clean. Carbon deposits and sludge will affect the cylinder compression ratio, valve tightness, and working condition of the fuel injector of the engine, reducing the power output of the engine. After changing the new engine oil, the cleanliness of the engine oil is improved, which can effectively remove the dirt inside the engine and restore the original performance of the engine, so that the car can speed up faster.
The oxidation resistance of the oil is improved. The oxidation resistance of engine oil refers to the ability of engine oil to resist oxidation reaction at high temperatures, prevent oil deterioration, and prolong the service life of engine oil. The oxidation reaction will darken the color of the engine oil, increase the viscosity, and generate some harmful substances, such as gum, asphaltene, etc., which will clog the oil filter, affect the circulation of the engine oil, and increase the wear of the engine. After changing the new engine oil, the oxidation resistance of the engine oil is improved, which can effectively inhibit the oxidation reaction and maintain the stability of the engine oil, so that the car can speed up faster.
To sum up, after changing the engine oil, the car speeds up quickly, because the new engine oil has better viscosity, cleanliness and oxidation resistance, which can effectively lubricate, cool, clean and prevent various parts inside the engine, improve the efficiency and performance of the engine, and make the car speed faster. Of course, the time and method of changing the engine oil should also be noted, it is generally recommended to change the engine oil every 5000 kilometers or half a year, and choose the appropriate oil brand and model when changing the engine oil, and follow the prescribed procedures and steps to ensure the effect and safety of the oil change.
