The low cold-cranking viscosity allows the oil to circulate quickly through the engine block and up to the valvetrain. This high number signifies that the oil maintains a thick, protective film even when the engine is running hot under heavy load.

Understanding the 5W-50 Viscosity Rating The numbers on a motor oil container, such as 5W-50, are not arbitrary; they are a standardized measurement of the fluid's viscosity, or its resistance to flow. European luxury brands, as well as many American performance models, often call for this specific grade to meet their stringent engineering requirements.
A rating of 5 means the oil flows easily at low temperatures, ensuring critical engine components are lubricated immediately upon startup, which reduces wear and tear. The 50 in the viscosity rating indicates that this formulation is designed to resist this thermal breakdown.

The "W" stands for Winter, and the number preceding it indicates the oil's cold-temperature viscosity. Unlike thicker oils, 5W-50 reduces the stress on the battery and starter motor, ensuring a smoother, easier cold start even in freezing temperatures.
