Choose the Suitable Engine Oil for your Car

2019-11-22

Buying a car can be an instant decision, but maintaining a car is a long-term task. Generally speaking, the running in period is about 5000 kilometers of the new car's initial driving. For a new car, the running in period is an important and special process: the metal contact surfaces of all parts in the car's power system are still uneven or burr in microcosmic sense, and the fitting clearance of parts is not even. In this stage, the fine bumps on the parts will be worn off, so that the fitting clearance of all moving parts will be intensified Dense, smoother movement.


The function of engine oil?

During the running in period of new cars, the anti-wear requirements of the engine oil are very high. Because of the uneven fit clearance within the engine, it is more difficult to form a smooth lubricating oil film, which leads to the lack of lubrication in some parts, resulting in wear, and even may cause serious consequences such as tile burning and cylinder pulling. Therefore, Antiwear Ep Additive should be added when produce the lubricant oil.

How to choose the suitable engine oil?
During the running in period, the engine oil with low viscosity is generally selected, and excellent antiwear performance is required. The oil with lower viscosity has better fluidity and cleanness, which can help heat dissipation more effectively and take away the fine debris produced by running in. Wear resistance refers to the ability of lubricating oil to avoid metal wear caused by contact when there is friction between metals. Better wear resistance helps the engine "smooth" through the running in period. The lubricant manufacturer can change the viscosity of lubricant by adding Viscosity Index Improver. According to the user's manual, it is recommended to carry out the first maintenance and oil change in the first 2000-3000 km of the new car.


There will always be a day when a new car will become an "old car", so what should be done to adjust the maintenance strategy for the old car? With the growth of vehicle age, it is necessary to comprehensively consider your driving habits and the performance requirements of the vehicle to adjust the oil products used. Oil with high viscosity can protect engine parts more, which is suitable for long-term high-temperature operation of the engine, filling the gap that engine becomes larger due to long-term operation. But the oil with low viscosity may be more fuel-efficient, the engine speed can be increased faster and the acceleration is sensitive.

So how to choose the suitable engine oil?

In consideration of the normal wear consumption of the engine, the larger the clearance between the mating surfaces and the viscosity of the engine oil, it should also be slowly increased with the increase of the age of the vehicle. Generally, it is recommended to use relatively thin engine oil for vehicles within 50000 km. After 50000 km, slowly increase the viscosity of the engine oil, which is also the most appropriate protection for the engine.
