In relation to oil, what does viscosity refer to?

Viscosity is a measure of a fluid's resistance to flow, which is often interpreted as the "thickness" of the oil. Fluids with high viscosity, like honey or motor oil, flow slowly compared to low-viscosity fluids, such as water or gasoline, which flow more easily. In the context of oil, understanding its viscosity is crucial because it affects how the oil performs in various applications, such as lubrication in engines or as a cooking ingredient. The weight of the oil also plays a role, as heavier oils tend to have higher viscosities. Therefore, recognizing viscosity in terms of thickness and weight is essential for both industrial uses and consumer applications.
