Which is better, high or low kinematic viscosity?

Whether high or low viscosity is better for sports depends on the specific application scenario and requirements.
High kinematic viscosity:
Advantages: Lubricating oils with high kinematic viscosity typically have better lubrication and sealing properties, providing better protection between heavy-duty or high-speed components.
Disadvantage: High viscosity lubricating oil may increase frictional resistance, thereby increasing energy consumption and equipment heating. Meanwhile, high viscosity lubricating oil may not flow easily at low temperatures, affecting the start-up performance of the equipment.
Low kinematic viscosity:
Advantages: Lubricating oil with low kinematic viscosity has better fluidity and permeability, and can quickly penetrate into every corner of the equipment, providing better lubrication effects. At the same time, low viscosity lubricating oil can maintain good fluidity at low temperatures, which helps with the smooth start-up of equipment.
Disadvantages: Low viscosity lubricants may not provide sufficient lubrication and sealing, especially under heavy load or high-speed operation conditions, which may lead to increased equipment wear.
Therefore, it is crucial to choose lubricating oil with appropriate kinematic viscosity. When selecting, factors such as the operating conditions, workload, temperature range, and required lubrication performance of the equipment should be considered.
