This figure represents the oil's viscosity at 210°F (100°C), which is the typical operating temperature of a running engine. Using the wrong SAE rating can lead to significant issues.
Understanding SAE Standards for Optimal Oil Performance
Decoding the SAE Viscosity Rating The Society of Automotive Engineers (SAE) created a uniform scale to classify the viscosity, or thickness, of engine oils. Conversely, a higher number means the oil is thicker when cold, which might be suitable for warmer climates but could delay lubrication in winter.
Selecting the correct viscosity grade ensures optimal lubrication, reduces wear, and helps maintain fuel efficiency. The number preceding the "W" (for example, the "5" in 5W-20) tells you how resistant the oil is to flow when cold.
Understanding SAE Standards for Optimal Oil Performance
Always consult your vehicle's owner manual for the manufacturer's recommended SAE grade. It signifies that the oil meets specific viscosity standards for low-temperature performance.
