How to select lubricant viscosity?

How to select the viscosity of lubricating oil?
Viscosity is only a physical indicator of lubricating oil. The quality of oil cannot be judged simply by viscosity, but the selected viscosity must be suitable for the working needs of your engine. If the selected viscosity is too high, the oil is too viscous, which will increase the movement resistance of the engine, generate too much heat, consume the power of the engine, and is not conducive to the normal operation of the engine. If the selected viscosity is too low, the oil is too thin, the oil film strength is reduced, and the wear of engine parts will increase, which will not protect the engine.

The correct choice should be to select the best viscosity according to the requirements of the automobile manufacturer and the actual use environment of the vehicle. It is best to use a multi-grade viscosity lubricant that can meet the needs of winter and summer use. Universal lubricants can maintain relatively stable lubrication performance regardless of temperature changes, and provide better protection for the engine.
