20-50 motor oil is a type of multigrade engine oil characterized by its viscosity ratings of 20 when cold and 50 when hot. This oil is designed to provide good lubrication and protection for engines operating in higher temperature conditions, making it suitable for older vehicles or those used in warmer climates. The "20" rating indicates that the oil flows well at lower temperatures, while the "50" rating ensures it maintains adequate thickness at high temperatures.
