Honda Genuine Power Steering Fluid is produced under contract for Honda by an approved supplier; the exact partner is not publicly disclosed. The fluid is formulated to Honda's specifications and sold through official Honda parts channels, with regional suppliers potentially varying by market.
What is Honda Genuine Power Steering Fluid?
Honda's hydraulic power steering system relies on a dedicated fluid designed specifically for that purpose. The Honda Genuine Power Steering Fluid (PSF) protects seals, maintains proper viscosity across temperature ranges, resists foaming, and helps prevent corrosion in the pump and lines. Honda recommends using this product or an equivalent that meets Honda's specification; using the wrong type — for example, conventional automatic transmission fluid or other hydraulic fluids — can cause poor steering feel and potential damage.
Who makes Honda Genuine Power Steering Fluid?
Honda does not publish the identity of the contract manufacturers that produce Honda Genuine Power Steering Fluid. Like many automakers, Honda outsources the manufacturing of certain fluids to approved suppliers under license to meet its exact specifications. The supplier may vary by region or over time due to supply chain arrangements, regulatory considerations, and regional partnerships, but the product remains Honda Genuine and carries Honda part numbers and branding.
Why the supplier is not publicly named
Automotive manufacturers commonly work with contract manufacturers for fluids and lubricants, and they typically do not disclose the exact partner publicly. Reasons include competitive secrecy, contractual agreements, and the desire to simplify regional sourcing. In practice, customers can rely on the Honda Genuine label as the authenticity indicator, regardless of which company produced the fluid in their market.
How to ensure you’re buying the right fluid
The safest path is to purchase Honda Genuine Power Steering Fluid from authorized Honda dealers, official parts websites, or service centers. In many markets, Honda packaging carries the Honda logo and a part number aligned with Honda's service manuals. If in doubt, consult your owner's manual or a Honda service professional before topping up.
Summary
Honda Genuine Power Steering Fluid is produced under contract for Honda by an approved supplier, with the exact manufacturer not publicly disclosed. The product is designed to meet Honda's specifications and is distributed through official channels to ensure compatibility with Honda power steering systems. For customers, the bottom line is to use Honda Genuine PSF or a proven equivalent that meets Honda's specification, and to rely on authorized outlets for purchase and guidance.
