Beike and Shell are not the same brand, and there is no connection between the two brands. Beike is a cottage brand and advocates that friends must not buy Beike engine oil. Shell is a world-renowned engine oil manufacturer and R&D company. D manufacturer, and Shell is also a partner of Ferrari. There are three major brands of engine oil that I often encounter, Shell, Castrol and Mobil. Although the prices of these three brands of engine oils are quite expensive, their lubricating performance is still quite good. Engine oil is indispensable for the normal operation of the engine. If there is no oil in the engine, the engine will not run normally. The engine oil not only plays the role of lubrication, but also has the functions of cleaning, sealing, buffering, rust prevention and heat dissipation. When the engine is running, the engine oil will form an oil film on the surface of each component in the engine, which can reduce the wear of each component in the engine. Encourage small partners to choose the viscosity suitable for their vehicle engine when purchasing oil. The viscosity of the engine should not be too high or too low. If the viscosity is too high, the resistance will increase when the engine is running, which will affect the power output and fuel consumption of the engine. If the viscosity is too low, the oil can't form a stable oil film on the surface of each component, which will aggravate the engine wear. The performance of the engine will basically decline after long-term use of engine oil. Of course, friends must change the oil on time. Every time you change the oil, you basically change the oil filter. Well, thank you for reading. This question ends here.
