What does 20W-50 mean?

20W-50 is a high-viscosity oil ideal for older engines, heavy-duty vehicles, and warm climates:

20W: The oil is thicker at low temperatures, making it less suitable for cold weather but effective in mild to hot climates.
50: The oil remains thick at high temperatures, providing strong protection for engines under heavy loads or prolonged operation.

20W-50 is often used in older cars, motorcycles, and industrial machinery. Its thick consistency helps seal engine parts, reduce oil consumption, and protect against wear in engines with high mileage or those subjected to extreme operating conditions.
