Performance at Operating Temperature While the "W" rating is essential for cold starts, the second number is equally vital for the health of your engine. This stability translates to better engine protection, especially in extreme conditions or during heavy towing.
Breaking Down the SAE Dual Number System for Engine Oil
This dual-number system provides a complete picture of how the oil flows through the engine's intricate passages. If the oil is too thick (high viscosity), it can cause poor fuel economy, reduced engine power, and difficulty starting in cold weather.
Using the wrong SAE rating can lead to significant issues. Decoding the SAE Viscosity Rating The Society of Automotive Engineers (SAE) created a uniform scale to classify the viscosity, or thickness, of engine oils.
