What is power steering oil used for?
This fluid is critical for providing its namesake system with hydraulic assistance so you can turn the steering wheel of your vehicle easily. It also helps lubricate the power steering pump and the steering components. Power steering fluid even prevents corrosion.
What are the commonly used power steering fluids?
Some use ATF transmission fluid such as Dexron, Mercon, Type F, ATF+4, etc.) but many newer vehicles use some type of synthetic-based hydraulic fluid that is specifically formulated for power steering use. Synthetic fluids flow well at low temperature, which improves pump lubrication and longevity.
