The thicker consistency at operating temperature helps maintain oil pressure, which is beneficial for engines with higher mileage and looser tolerances. Drivers who live in areas with hot summers and cold winters often find 15w 40 to be a reliable, all-season solution.
Understanding Stop Start Technology in 15w 40 Motor Oil
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. Compared to 10w 40, the 15w variant flows slightly better when cold, making it easier for the engine to turn over in lower temperatures.
Ideal Applications for This Viscosity This specific oil is frequently recommended for certain types of vehicles and driving scenarios. At lower temperatures, it flows easily to protect engine components during startup, while at higher temperatures, it maintains a stable, thick enough film to prevent metal-to-metal contact.
