Is it necessary to choose oil with high viscosity in summer?
In summer, with the gradual rise in temperature, the engine of the car is also facing higher working temperature and pressure. In such a season, the choice of oil is particularly important, because it is directly related to the lubrication effect and operation stability of the engine. On whether we must choose oil with high viscosity in summer, this problem actually involves many aspects of consideration.
First of all, we need to understand that oil viscosity refers to the flow of oil at a specific temperature. Oil with high viscosity can better maintain its lubrication performance at high temperatures and is not easy to thin, thus ensuring that the engine can still be adequately lubricated at high temperatures. This is undoubtedly beneficial to reduce engine wear and increase engine life.
However, this does not mean that the summer must choose a high viscosity oil. Because, too high viscosity can also cause some problems. High-viscosity oil has poor fluidity at low temperatures, and it is difficult to reach the lubricating part quickly when starting the engine, which may lead to increased engine wear. In addition, high-viscosity oil will also increase the fuel consumption and emissions of the engine, which is not conducive to energy conservation and environmental protection.
Therefore, when choosing oil, we need to consider comprehensively according to the use environment of the vehicle and the requirements of the engine. If the vehicle often works in a high temperature, high load environment, it may be appropriate to choose a slightly higher viscosity oil. However, if the vehicle is mainly driven in an environment with low load and large temperature changes such as urban areas, then it may be more appropriate to choose an oil with moderate viscosity or excellent low temperature fluidity.
In addition, in addition to viscosity, we also need to pay attention to other performance indicators of oil, such as oxidation resistance, cleaning and dispersion. These performance indicators also have an important impact on the lubrication effect and life of the engine. Therefore, when choosing oil, we should choose those oil products with good comprehensive performance, rather than just focusing on the viscosity of this single indicator.
In short, there is no absolute answer to whether the oil with high viscosity must be selected in the summer. We need to make choices based on the actual use of the vehicle and the requirements of the engine. At the same time, we also need to pay attention to other performance indicators of the oil to ensure that the engine can still be fully lubricated and protected in high temperature environments.
Finally, it is recommended that car owners consult professional auto repair shops or car manufacturers when choosing oil to ensure that they choose the right oil products for their vehicles. At the same time, it is also necessary to regularly replace the oil and oil filter, maintain the good condition of the engine, and extend the service life of the vehicle.
In the high temperature season of summer, let's choose the right oil for the car, provide adequate lubrication and protection for the engine, and ensure the safe, stable and efficient operation of the vehicle.
