The "15w" signifies its low-temperature viscosity, where the "W" stands for winter, and the number indicates how readily the oil flows when the thermometer drops. In frigid conditions, the oil remains pourable and quickly reaches the upper engine, minimizing the dry start period that causes the majority of engine wear.
