What is the proper method for selecting power steering fluid?

Selecting the proper power steering fluid is crucial for the safe and efficient operation of a vehicle’s steering system. The best practice is to adhere to the manufacturer-recommended specifications. Each vehicle manufacturer has specific requirements regarding the type of fluid that should be used in their vehicles. This includes the fluid’s viscosity, chemical composition, and potential additives that may be necessary for optimal performance.

Using fluids that meet these specifications ensures that the power steering system functions correctly and helps prevent issues such as steering difficulties or potential damage to the steering components. Manufacturer recommendations can typically be found in the vehicle’s owner’s manual or service guidelines, providing detailed information about the required fluid type.

Though other options may seem convenient—such as relying on compatibility from nearby stores, matching fluid colors, or considering price and availability—these methods carry risks. Without aligning with manufacturer specifications, there is a higher likelihood of suboptimal performance or even damage, leading to increased maintenance costs and safety concerns. Therefore, following the manufacturer's guidelines is the most reliable method to ensure the longevity and effectiveness of the power steering system.
