Common Misconceptions and Myths. 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.
Hot Temperature SAE Oil Behavior and Engine Protection
Decoding the SAE Viscosity Rating The Society of Automotive Engineers (SAE) created a uniform scale to classify the viscosity, or thickness, of engine oils. In hot summer climates, drivers might opt for a 10W-40 or 15W-40 to provide a thicker oil film that resists thinning under high stress and heat.
Conversely, a higher number means the oil is thicker when cold, which might be suitable for warmer climates but could delay lubrication in winter. Always consult your vehicle's owner manual for the manufacturer's recommended SAE grade.
Hot Temperature SAE Oil Behavior and Viscosity Stability
This stability translates to better engine protection, especially in extreme conditions or during heavy towing. Seasonal Considerations and Climate Climate plays a significant role in determining the best SAE grade for your vehicle.
