Understanding Motor Oil Viscosity

You’ll feel the difference in thickness as you pour motor oil into your car’s engine, and it’s important to understand how this consistency affects the way it flows through your vehicle’s intricate network of parts. Viscosity grades, which are represented on an oil container as a series of numbers and letters (e.g., 5W-30), indicate the oil’s resistance to flow at different temperatures. The "W" stands for winter, and the number preceding it represents how well the oil flows in cold weather. The second number indicates how effectively it lubricates an engine at high temperatures.

Engine lubrication is critical because all engines generate heat from friction between moving parts. If those parts don’t have adequate lubrication, they can seize up and suffer irreparable damage. Motor oil ensures that these components remain slippery enough to move against one another without grinding together. However, if the viscosity grade is too low or high for your specific engine type, you may encounter difficulties with performance or even experience engine failure over time. That’s why choosing the right viscosity grade is essential in maintaining optimal engine health.

5W20 vs 5W30: Which One is Right for Your Engine?
