The “W” in 10W40 oil stands for “Winter,” indicating the oil’s viscosity classification at low temperatures. The number before the W, 10 in this case, represents the oil’s viscosity at cold temperatures, meaning it has a viscosity rating of 10 in low temperatures, making it relatively thin and capable of flowing easily to lubricate engine parts during cold starts. The number after the W, 40, tells you the viscosity of the oil at high temperatures, indicating it is thicker at 100 degrees Celsius, which ensures it can maintain a good film strength and protect the engine at operating temperatures. The dual rating shows it can perform in both cold and hot conditions, making it a versatile choice for a wide range of climates and driving conditions.
