Power steering fluid cannot be replaced with engine oil. Power steering fluid, also known as hydraulic steering fluid, is specifically designed for use in a car's power steering pump. It utilizes hydraulic pressure to make steering wheel operation easier. Engine oil serves a different purpose and cannot achieve the same effect. Power Steering Fluid: Power steering is a modern technology that enhances driving comfort by automatically providing steering assistance during turns, thereby reducing the driver's effort. Power steering fluid is a specialized medium added to the power steering system to transmit steering force and provide cushioning. It cannot be substituted with engine oil. Consequences: Using engine oil as a substitute would cause severe internal wear in the steering gear, adversely affect engine performance, and potentially accelerate damage. Power steering fluid is essentially a hydraulic oil that operates in a closed system and does not require cleaning.
