What is the temperature range for 20W-50 engine oil?
20W-50 is a multi-grade engine oil suitable for a wide range of temperatures. The "W" stands for "winter," and the number before the "W" indicates the oil's viscosity at low temperatures. In this case, 20W means that the oil has a viscosity of 20 when tested at cold temperatures. The number after the "W" signifies the viscosity of the oil at high temperatures; in this case, 50 signifies a viscosity of 50 when tested at hot temperatures. Therefore, the temperature range for 20W-50 engine oil is generally between -10°C (14°F) and 40°C (104°F). However, depending on the region and specific vehicle recommendations, this range may vary. It's crucial to consult the owner's manual or specifications provided by the vehicle manufacturer to select the appropriate engine oil and ensure suitable performance and protection for your vehicle.
