What is the viscosity of lubricating oil? A comprehensive guide to viscosity

1. What is viscosity? Why is viscosity important when choosing lubricants for vehicles?

2. How is viscosity measured?

• Low-viscosity oil can be described as thin and lightweight.
• High-viscosity oil can be described as thick and heavy.
• Low-viscosity engine oil (0W-20) flows faster than high-viscosity oil (20W-50).

3. What is kinematic viscosity?

4. How to understand dynamic absolute viscosity?

5. Learn about the Viscosity Index.

6. How to choose the appropriate viscosity.

• Increased contact, friction, and wear between engine components.
• Increased oil consumption.
• Rubber seals leaking.
• Increased friction and temperature during engine operation.
• Poor flow and lubrication at low temperatures.
• Reduced energy efficiency.

• Extended oil change intervals.
• Maximum fuel savings.
• Reduced engine wear.
• Decreased oil consumption and emissions.
• Superior performance in extreme temperatures.
