Can I use Prestone power steering fluid in my Subaru?

Yes, often you can use a Dexron II/Mercon‑compatible power steering fluid like Prestone, provided your Subaru’s owner’s manual allows ATF in the power steering system. Always verify the exact specification for your model and year, since some Subarus require a dedicated Subaru Power Steering Fluid.


The question arises because Subaru models vary in their fluid specifications over different generations. Some use automatic transmission fluid (ATF) in the power steering circuit, while others call for a specific Subaru PSF. Using the wrong fluid can damage seals and the pump, so it’s essential to confirm the correct type before refilling.


To determine whether Prestone is compatible with your Subaru, review the steps below and follow the guidance to avoid damaging the system.


To determine compatibility, follow these steps:



  • Check the owner’s manual for the recommended power steering fluid specification (look for ATF Dexron II/III, Dexron VI, or a note to use Subaru PSF).

  • Inspect the power steering fluid reservoir cap or nearby markings for the specified fluid type.

  • Note your Subaru model year and engine, since fluid requirements can change across generations.

  • Verify that the Prestone product you choose explicitly states compatibility with the required specification (e.g., Dexron II/III or Dexron VI). Do not assume; read the label.

  • If you’re uncertain or your manual calls for Subaru PSF, consult a Subaru dealer or a qualified mechanic before refilling or flushing the system.


Conclusion: If your manual indicates ATF or a Dexron‑type specification for the PS system, a Prestone product that is Dexron II/III or Dexron VI compatible can be appropriate. If your Subaru requires dedicated Subaru PSF only, do not substitute with generic ATF. When in doubt, use the fluid exactly specified by Subaru and have the system bled properly after any service.


Summary


Bottom line: Check your owner’s manual to determine the exact power steering fluid specification for your Subaru. Many models permit a Dexron II/III or Dexron VI ATF‑type PS fluid such as Prestone, but some require Subaru’s own PSF. Using the wrong fluid can cause damage, so verify before refilling or flushing the system.

Can I put any brand of power steering fluid in my car?
