Conversely, in hot summer climates or during sustained high-speed driving, the 40-grade stability prevents the oil from thinning out too much. These molecules are uniform in size and shape, reducing friction and allowing the engine to operate more efficiently.

This ensures that the oil film between moving parts remains thick enough to prevent metal-to-metal contact, providing a crucial safety net for the engine under severe stress. The number following the 'w' denotes the thickness of the oil at 100°C (212°F), with 40 indicating a high level of resistance to shear and breakdown.
Most modern European vehicles, including models from BMW, Mercedes-Benz, and Volkswagen, often specify this exact viscosity for optimal performance and to satisfy warranty requirements. This efficiency translates directly to better fuel economy and reduced engine wear over the lifecycle of the oil.

American and Asian manufacturers also utilize this grade in specific high-output or turbocharged applications. The number preceding the 'w' indicates cold-weather performance, where zero represents the lowest viscosity available for easy engine startup.
