It is designed to flow well enough in moderate winter climates without being too thin. The choice ultimately depends on the engine design, climate, and the manufacturer's recommendations.
Understanding 15w 40 Motor Oil Pressure Maintenance for Optimal Engine Health
A rating of 15 indicates that the oil is slightly thicker than lower numbers, such as 5w or 10w, when cold. Compared to 10w 40, the 15w variant flows slightly better when cold, making it easier for the engine to turn over in lower temperatures.
Understanding 15w 40 motor oil starts with decoding its viscosity grade, a number that reflects its performance across a wide temperature range. Decoding the Numbers: What 15w 40 Really Means The "15" in 15w 40 represents the oil's cold-temperature viscosity, with the "W" standing for winter.
