The extremely low viscosity can be a disadvantage in very high-mileage engines, where internal clearances have increased over time. This grade is commonly recommended by European manufacturers, including Volkswagen, BMW, and Mercedes-Benz, and is compatible with both gasoline and diesel engines, provided it meets the specific OEM certifications required for the vehicle.
Long Term Engine Benefits of 0w 40 Oil
The "w" stands for winter, and the "40" represents its thickness at the engine's normal operating temperature, measured in centistokes at 100°C. Furthermore, the instantaneous lubrication provided by the thin, cold fluid significantly reduces wear on the engine during the initial seconds after startup, a period when most engine wear occurs.
Furthermore, because this oil is designed to meet stringent modern specifications, it may not be suitable for classic cars with original, narrow tolerances that were designed for older, higher-viscosity oils. The additive package is where the engineering truly comes to life, incorporating viscosity index improvers to ensure the oil flows readily when cold yet thickens appropriately when hot.
