Benefits for Modern Engines Manufacturers design contemporary engines with tighter tolerances and lighter components to improve fuel efficiency and power output. Once the engine reaches operating temperature, the higher viscosity grade ensures that critical moving parts, such as the camshaft and connecting rods, remain separated by a durable oil film, preventing metal-to-metal contact and extending engine life.

Furthermore, because they are designed to shear back to a stable viscosity, they maintain their efficiency throughout the oil change interval. Seasonal Performance and Efficiency One of the primary advantages of using multigrade oil is the convenience and protection it offers across all seasons.
The number preceding the "W" denotes the oil's cold-start performance, specifically its viscosity measured at -17. This eliminates the need for seasonal oil changes in most climates, simplifying maintenance for the driver.
Troubleshooting Common Issues with Multigrade Oil Performance
Understanding the Viscosity Code The defining characteristic of any multigrade oil is its viscosity rating, which is printed on the container as a code such as 5W-30, 10W-40, or 0W-20. High Mileage Formulations For drivers with vehicles that have accumulated significant distance, specialized high-mileage multigrade oils are available.
