Does Acura need special power steering fluid?

Yes for most Acura vehicles with hydraulic power steering, you should use Honda/Acura Power Steering Fluid (PSF) rather than generic fluids. Always verify with your owner's manual. Some newer Acura models use electric power steering (EPS) and do not require hydraulic PSF at all.

Understanding Acura power steering fluid requirements

Power steering systems in vehicles are not all the same. Acura/ Honda hydraulic systems are designed to work with a specific PSF that is formulated to protect seals and maintain optimal steering feel. Using the wrong fluid can lead to leaks, degraded performance, or premature wear. If your vehicle uses EPS, there is no PSF reservoir in the system and no PSF fill is required.

Core fluid recommendations for Acura models

Before listing fluid options, it’s important to know whether your Acura uses a hydraulic power steering system or EPS. If your car relies on hydraulic PS, follow the guidance below.

• Honda/Acura Power Steering Fluid (PSF) — OEM-recommended for most hydraulic PS systems in Acura models. This is the safest default choice for compatibility and seal protection.


• Dexron-type automatic transmission fluid (ATF) — Some older Acura/Honda service manuals list ATF as acceptable in certain models or years, but this is not universal. Always check your specific owner's manual or dealer guidance before using ATF in a hydraulic PS system.


• Do not use generic ATF unless your manual explicitly allows it. Mixing fluids or using a fluid not approved for Honda/Acura PSF can damage seals and reduce steering performance.


• If your model uses electric power steering (EPS), no PSF is needed and you should not add hydraulic PSF to the system.

In short, the safest path is to use Honda/Acura PSF for hydraulic systems and to confirm EPS status before adding any fluid

How to check and refill power steering fluid

If your vehicle uses hydraulic PSF, follow these practical steps to maintain proper fluid level and system health.

• Park on a level surface, engine off and cold before checking the reservoir. Locate the power steering fluid reservoir under the hood.


• Check the level against the marked MIN and MAX lines. If low, add PSF gradually in small amounts.


• With the engine running, turn the steering wheel from lock to lock several times to bleed air from the system, then recheck the level and top off if needed.


• Inspect for leaks around hoses, clamps, and the reservoir. A persistent drop in fluid level indicates a leak that should be repaired.


• Use only the recommended PSF. Never mix PSF with other fluids unless explicitly allowed by your manual.

Following these steps helps maintain steering performance and prevents air pockets or seal damage. If you notice persistent noise, stiffness, or hard steering, have the system inspected by a professional.

Where to buy and how to choose

Choosing the right fluid is easier when you know where to buy and what to look for.

• OEM Honda/Acura Power Steering Fluid — purchase from a dealership or authorized parts retailer to ensure correct formulation and compatibility.


• Approved equivalents — some reputable brands offer PSF formulations specifically labeled as compatible with Honda/Acura PSF. Look for clear labeling that states compatibility with Honda/Acura hydraulic power steering systems.


• Avoid unverified or generic ATF products unless your manual confirms they are acceptable for your model. Incorrect fluid can damage seals and components.


• When in doubt, consult your dealer or a qualified mechanic to confirm the correct fluid for your exact year and model.

EPS vs hydraulic nuance

As a reminder, several newer or redesigned Acura models may use electric power steering (EPS). In those vehicles, there is no hydraulic PSF reservoir, and the fluid discussion above does not apply. If you’re unsure whether your car has hydraulic PSF or EPS, check the owner’s manual or contact a dealer.

Summary

For most Acura models with hydraulic power steering, you should use Honda/Acura Power Steering Fluid (PSF) as the OEM-recommended fluid. Verify your vehicle’s system type (hydraulic PSF vs. EPS) in the owner’s manual. Do not mix fluids, and avoid using non-approved brands unless explicitly allowed by your manual. If uncertain, consult your dealer for the exact specification for your year and model.

Can I use regular power steering fluid in my Honda?

No, you cannot use regular power steering fluid in a Honda; you should use the genuine Honda-brand fluid or a product specifically labeled as compatible with Honda vehicles. Using the wrong fluid can cause significant damage to the power steering pump and other components, leading to costly repairs. 
Why you must use the correct fluid

• Specific formula: Honda power steering fluid has a proprietary mineral oil-based formula with a specific blend of additives designed to work with Honda's power steering system seals and racks. 
• Damage risk: Generic power steering fluids have different chemical compositions that can cause seal swelling, leaks, and chatter, and they may not provide proper lubrication for Honda's specific components. 
• Costly repairs: Damage from using the wrong fluid can be expensive to fix, especially since replacing the power steering rack on some Honda models is a labor-intensive job. 

What to do instead

• Buy Honda Genuine Fluid: The safest option is to purchase Genuine Honda Power Steering Fluid from a Honda dealership or a parts retailer. 
• Find a compatible alternative: If you can't find the Honda brand, look for aftermarket fluids that specifically state they are compatible with Honda vehicles. 
• Consult your owner's manual: Always check your vehicle's owner's manual to confirm the recommended type of power steering fluid. 

Does it matter what kind of power steering fluid you put in?

Yes, it is critical to use the correct power steering fluid, as using the wrong type can cause significant damage to the system, including the pump and seals. The correct fluid specification can be found in your vehicle's owner's manual, and is essential for proper steering performance and longevity. 
Why the correct fluid is important

• Prevents damage: Power steering systems have very specific requirements. Using the wrong fluid can cause seals to swell or other components to fail, leading to leaks and a shortened lifespan for the system. 
• Maintains performance: The correct fluid ensures consistent and smooth power assistance. The wrong fluid can lead to poor steering performance, making the wheel feel stiff or inconsistent. 
• Avoids noise: An incorrect fluid can cause the pump to make whining noises, which is a sign of a system under stress. 

How to find the right fluid

• Check your owner's manual: This is the most reliable source for the specific type of fluid your vehicle needs. 
• Look for labels: The correct specification is often printed on the power steering fluid reservoir cap. 
• Consult service information: If the information isn't on the cap or in the manual, a service technician can look it up in the vehicle's service information. 
• Consider your vehicle's age: Some manufacturers used specific types of fluid (like certain automatic transmission fluids) in older vehicles, while most newer cars require a dedicated synthetic power steering fluid.
