Understand Motor Oil Viscosity Ratings

Your motor oil's viscosity rating might seem mysterious, so let's demystify it now. First, let's cover the concept of viscosity. It measures a fluid's resistance to flow. Think of a pitcher of iced tea. If you bump it, the tea will slosh. Therefore, tea and similar beverages are low-viscosity fluids. Conversely, a freshly made milkshake flows much slower than iced tea. Thus, milkshakes are high-viscosity fluids. What does this mean for your motor oil?

On the side of a motor oil container, we find two numbers with a W and a hyphen between them, such as 5W-20 or 10W-30. Those are motor oil viscosity ratings. The value before the W is an oil's viscosity at low temperatures, and the value after the hyphen is the oil's viscosity at high temperatures.
