Understanding Engine Oil Viscosity: What Does Oil Viscosity Mean?
Before diving into the specifics of amsoil 0w20 vs 5w30, let’s clarify what those numbers actually mean. Engine oil viscosity is a measure of its resistance to flow.
Think of it like honey versus water. Honey has a higher viscosity; it flows slowly. Water has a lower viscosity; it flows quickly. For engine oil, this “flow” characteristic changes with temperature.
Decoding the Numbers: “W” and Hot Viscosity
Every multi-grade engine oil, like Amsoil’s offerings, has two numbers separated by a “W.”
- The first number, followed by “W” (which stands for Winter), indicates the oil’s viscosity at cold temperatures. A lower number means the oil flows more easily when cold. This is crucial for cold starts and rapid lubrication.
- The second number represents the oil’s viscosity at normal operating temperatures (typically around 212°F or 100°C). A higher second number means the oil maintains a thicker film at hot temperatures, offering more protection against wear.
So, when we look at Amsoil 0w20 vs 5w30, we’re primarily comparing their cold-start characteristics and their hot-weather protection capabilities. The goal is always to have oil that flows quickly when cold but remains robust enough when hot.
