What is 20W-40 Engine Oil?
20W-40 engine oil is a type of multi-viscosity engine oil that is designed to provide optimal performance in a wide range of temperatures. The “20W” part of the label refers to the oil’s viscosity at low temperatures, while the “40” part refers to its viscosity at high temperatures.
Viscosity at Low Temperatures
The “W” in 20W stands for “winter,” and it refers to the oil’s viscosity at low temperatures. In other words, 20W-40 oil has a viscosity of 20 at temperatures below 0°C (32°F). This means that the oil is designed to flow easily and lubricate the engine’s components even in cold weather conditions.
Viscosity at High Temperatures
The “40” part of the label refers to the oil’s viscosity at high temperatures. In other words, 20W-40 oil has a viscosity of 40 at temperatures above 100°C (212°F). This means that the oil is designed to provide adequate lubrication and protection to the engine’s components even in hot weather conditions.
