The Science Behind Cold Weather Performance Low-temperature viscosity is critical because engines experience the most stress during startup. This ensures a durable lubricant film that prevents metal-to-metal contact, minimizes friction, and prevents excessive oil consumption during high-speed driving or heavy loads.

However, synthetic formulations often provide advantages in maintaining viscosity stability across extreme temperature ranges. This ensures a durable lubricant film that prevents metal-to-metal contact, minimizes friction, and prevents excessive oil consumption during high-speed driving or heavy loads.
The "W" stands for winter, indicating the oil's cold-temperature performance, while the number preceding it signifies the viscosity when cold. Always refer to your vehicle's owner manual to confirm the recommended SAE rating for your engine.

When temperatures drop, oil thickens, making it difficult to pump through the engine's intricate passages. This allows the engine to receive immediate lubrication, reducing wear on critical components like bearings and camshafts during the moments after ignition.
