What oil can be used as a substitute for power steering fluid?
2 Answers
Power steering fluid cannot be replaced with other oils. Power steering is a new comfort-enhancing technology in automobiles that automatically provides steering force when the driver turns the wheel, thereby reducing the driver's steering effort. Power steering fluid is a medium oil added to the power steering system, serving to transmit steering force and provide cushioning. Additional information is as follows: 1. Power steering fluid: Power steering fluid is a transmission fluid, with a critical indicator being its low-temperature fluidity. Even when temperatures drop to several tens of degrees below zero, it does not thicken, allowing the steering system to operate smoothly. 2. Transmission oil: Transmission oil is a lubricant that maintains the cleanliness of the transmission system, ensuring proper operation and extending the lifespan of the transmission components.
I suggest not to use substitutes for power steering fluid casually, as it's not ordinary engine oil. Back when I worked at a repair shop, I encountered many car owners who used the wrong fluid and ended up damaging their entire power steering pump. For instance, one guy used engine oil as a replacement, and after just one drive, he noticed heavier steering and strange noises. Power steering fluid is specifically designed to lubricate and transmit pressure in the system. If you must use a substitute, only consider automatic transmission fluid (ATF), which can serve as a temporary fix in some older vehicles. But that should only be in emergencies, and never for long-term use. From my experience, if you notice reduced power assistance or any leaks, park the car immediately and check the fluid level. If it's low, top it up with the correct type of fluid. Don't overlook this small component during regular maintenance—safety comes first. Check your vehicle's manual for the recommended brand of fluid, or simply visit a repair shop and let them handle it.
