Should I use OEM power steering fluid?


When it comes to maintaining your vehicle's power steering system, choosing the right fluid is crucial. One common question many car owners ask is whether they should use OEM (Original Equipment Manufacturer) power steering fluid or opt for an aftermarket alternative. In this article, we’ll explore the importance of using the correct power steering fluid and help you make an informed decision.


What Is OEM Power Steering Fluid?


OEM power steering fluid is the fluid specifically designed and approved by your vehicle's manufacturer for use in your car. It is formulated to meet the exact specifications and requirements of your vehicle's power steering system. This ensures optimal performance, longevity, and compatibility with the system's components.


Why Does the Type of Power Steering Fluid Matter?


Using the correct type of power steering fluid is essential for several reasons:



  • Compatibility: Power steering systems are designed to work with specific fluid formulations. Using the wrong fluid can lead to poor performance or even damage to the system.

  • Performance: OEM fluids are engineered to provide the best performance for your vehicle, ensuring smooth and efficient steering.

  • Longevity: The right fluid helps prevent wear and tear on the power steering pump, hoses, and seals, extending the life of the system.

  • Warranty Compliance: Using non-OEM fluids may void your vehicle's warranty if it leads to system failure.


When Should You Use OEM Power Steering Fluid?


In most cases, it is highly recommended to use OEM power steering fluid, especially if your vehicle is still under warranty or if the manufacturer explicitly specifies it in the owner’s manual. Here are some scenarios where OEM fluid is a must:



  • If your vehicle has a unique or specialized power steering system, such as electric-hydraulic systems found in some modern cars.

  • If the manufacturer has issued a technical service bulletin (TSB) recommending a specific fluid.

  • If you want to ensure maximum performance and reliability from your power steering system.


Are Aftermarket Fluids Ever a Good Option?


While OEM fluids are generally the safest choice, some high-quality aftermarket fluids can be suitable alternatives. However, it’s crucial to ensure that the aftermarket fluid meets or exceeds the specifications outlined in your vehicle’s owner’s manual. Look for fluids labeled as "compatible with" or "meets the requirements of" your vehicle's make and model.


Conclusion: Stick with OEM for Peace of Mind


When it comes to your vehicle's power steering system, using OEM power steering fluid is often the best choice. It ensures compatibility, optimal performance, and long-term reliability. While aftermarket options may work in some cases, they come with risks that could lead to costly repairs down the road.
