Best Power Steering Fluid For Mercedes: OE and CHF Options
A strong choice for a Mercedes is a fluid that matches the exact specification in the vehicle’s manual or reservoir label; genuine Mercedes-Benz bottles suit owners prioritizing an OE part, while CHF-compatible products offer alternatives when that specification is confirmed. This roundup compares ten products, including Mercedes-branded fluids, a fluid identified as Mercedes-Benz 345.0 genuine OE, and multi-vehicle synthetic formulas. The distinction matters: a broad compatibility claim is not proof that a particular fluid is right for every Mercedes.
Check the required fluid code before buying, especially when comparing hydraulic fluids with different part numbers or approvals. The listings provide useful clues, but they do not establish fitment for every model or year.
Our rankings favor Mercedes-specific identification and listed approvals before general-purpose claims.
Mercedes-Benz Power Steering Fluid 345.0 Genuine OE leads because its listing identifies it as genuine OE fluid and gives the Mercedes-associated 345.0 designation. It is the clearest match here for a buyer whose vehicle calls for that specification. If your manual instead names a different Mercedes part number or hydraulic-fluid requirement, choose the corresponding genuine bottle or verify an alternative’s listed approval before use.
The broad-compatibility products should not be treated as universal substitutes without confirming the required specification.

Detailed Reviews: Best Power Steering Fluid For Mercedes

#1 · Best Overall
1. Mercedes-Benz Genuine OE 345.0
- Container Type: Bottle
- Form: Liquid
Best for: Mercedes OE fluid specification.
Why it ranks #1: The listing identifies this as Mercedes-Benz genuine OE fluid and specifies 345.0, making it the clearest Mercedes-specific match when that requirement applies.
The Mercedes-Benz Genuine OE 345.0 designation is the defining detail here, giving buyers a named original-equipment fluid specification rather than a broad, multi-make compatibility list. The one-liter liquid bottle provides a straightforward quantity for service, while the Mercedes-Benz branding makes its intended product identity clear.
This listing names Mercedes-Benz Power Steering Fluid 345.0 and identifies the product as Genuine OE, useful details for buyers matching a service requirement that specifies that fluid. The one-liter bottle contains liquid, making it a conventional fluid purchase for a planned maintenance job. The supplied information does not state further vehicle applications, operating-temperature properties, or fluid composition, so buyers should rely on the exact specification called for by their vehicle rather than infer additional capabilities.
- Mercedes-Benz Genuine OE designation
- 345.0 specification named in title
- One-liter bottle
- Liquid form for fluid service
- The listing provides no further vehicle application or fluid-composition details.
Skip it if you want synthetic CHF-11S fluid with a stated cold pour point; Triax Powerfluid 450 lists both features.
This suits Mercedes owners whose service requirement calls for the named Genuine OE 345.0 fluid and who want a one-liter bottle. The supplied listing is brief, so use the vehicle’s specified fluid requirement to judge application.

#2 · Direct Replacement
2. Mercedes-Benz Genuine 001-989-20-03-12
Best for: Direct replacement part match.
Why it ranks #2: This is listed as genuine Mercedes-Benz fluid and a direct replacement, and it replaces part number 001-989-20-03-10.
A genuine Mercedes-Benz direct-replacement listing identifies part 001-989-20-03-12 and says it replaces 001-989-20-03-10, giving buyers concrete references for a parts match. Those details make this product especially relevant when a service plan or existing reference calls for one of the listed numbers.
The listing identifies the product as genuine OEM Mercedes-Benz power steering fluid and labels its fitment type as direct replacement. It also names the replaced part number, providing a practical cross-reference for buyers checking a service requirement. The supplied details do not give fluid composition, bottle quantity, or a separate approval, so the part-number match is the strongest available basis for evaluating it. Buyers should use the specified reference rather than assume broader compatibility across Mercedes models.
- Genuine Mercedes-Benz OEM identification
- Power steering fluid named
- Direct-replacement fitment type stated
- Replacement part number provided
- The supplied listing gives no fluid composition or bottle quantity.
Skip it if you need a listed MB-Approval 345.0 rather than a replacement-part reference; Silkolene Titan CHF 11S states that approval.
This fits buyers matching Mercedes power-steering fluid by the listed OEM part number or its stated replacement reference. It is a focused part-number listing, so buyers without that reference should establish their vehicle’s required fluid before choosing.

#3 · Genuine Part
3. Genuine Mercedes Q1460001
- Container Type: Bottle
- Form: Liquid
- Material: Mineral, Synthetic
Best for: Genuine Mercedes part buyers.
Why it ranks #3: The genuine Mercedes listing identifies steering fluid and notes the newer part number Q1460002, giving owners a Mercedes-specific part reference to check.
A Genuine Mercedes-branded bottle with no modification required gives buyers a ready-to-install fluid option in a straightforward single quantity. The listing identifies it as power steering fluid and notes that the supplied replacement part number is Q1460002, a detail worth keeping in mind when matching it to a service need.
The listing calls this a genuine Mercedes power steering fluid and describes it as ready to install, so the purchase is framed as a direct service item rather than a treatment with additional steps. Its liquid form comes in a bottle and the material is listed as mineral and synthetic. The product information also says Q1460002 is the new part number and is what buyers will receive; that makes the stated replacement number important when identifying the bottle for a planned service.
- Genuine Mercedes brand
- Identified for steering-fluid use
- Ready to install with no modification required
- Mineral and synthetic materials listed
- The listing does not specify vehicle applications or fluid standards.
Skip it if you need an explicitly listed fluid approval; Silkolene Titan CHF 11S lists MB-Approval 345.0.
This suits buyers seeking a genuine Mercedes-branded steering-fluid bottle that is ready to install. Check the listed Q1460002 replacement number against the fluid required for your service, since application and approval details are not provided here.

#4 · Hydraulic System Fluid
4. Mercedes-Benz 000 989 91 03 10
- Container Type: Bottle
- Form: Liquid
- Material: Mineral Oil, Synthetic
Best for: Genuine hydraulic fluid buyers.
Why it ranks #4: This genuine Mercedes-Benz hydraulic fluid has a specific part number and is described for hydraulic systems, though the listing does not establish fitment for every Mercedes.
A genuine Mercedes-Benz hydraulic-system fluid in a liquid bottle gives buyers a clearly branded option for a hydraulic-fluid service. The listing identifies the fluid by its Mercedes part number and interchanges, while its mineral-oil and synthetic material description distinguishes the formulation information supplied for this product.
The product is identified as Mercedes-Benz hydraulic system fluid, with part number 000 989 91 03 10 and several listed interchange numbers. That identification can help buyers compare a required part reference with the supplied listing before a service. The fluid is described as a liquid in a bottle and its materials include mineral oil and synthetic. The supplied information does not name a specific steering application or approval, so it should not be treated as confirmed for every Mercedes power-steering system.
- Mercedes-Benz genuine brand
- Identified as hydraulic system fluid
- Part number and interchange references supplied
- Mineral oil and synthetic materials listed
- The listing does not specifically identify a power-steering application.
Skip it if you need explicit power-steering CHF-11S compatibility; Triax Powerfluid 450 lists that use and Mercedes-Benz compatibility.
This suits buyers matching the listed Mercedes hydraulic-fluid reference or interchange numbers for a service. Because the supplied description does not specifically name power steering or a fluid approval, confirm that the required system calls for this fluid.

#5 · CHF-11S Coverage
5. Triax Powerfluid 450
- Container Type: Bottle
- Form: Liquid
- Material: Synthetic
Best for: Broad European vehicle coverage.
Why it ranks #5: The synthetic fluid is specified for CHF-11S applications and lists Mercedes-Benz among compatible vehicles, making it a useful alternative when the required fluid matches.
A synthetic PAO-and-ester formulation paired with stated Mercedes-Benz compatibility makes Triax Powerfluid 450 a broad-coverage option for owners whose vehicle calls for CHF 11S fluid. Its listed compatibility also spans numerous European, American, and Asian makes, while an arctic-grade -76°F pour point addresses very cold conditions.
The product is specified for CHF-11S applications and names Mercedes-Benz among its compatible makes, giving buyers a useful starting point for vehicles requiring that fluid family. Its synthetic PAO and ester formulation is described as fill-for-life, which can suit owners seeking a long-life service fluid. The -76°F pour point supports use in arctic conditions, and the listed bottle format makes it a conventional liquid refill rather than a specialized installation system.
- Mercedes-Benz compatibility is stated
- Specified for CHF-11S applications
- Synthetic PAO and ester formulation
- -76°F pour point listed
- The listing’s fill-for-life claim does not provide a specific service interval.
Skip it if you need a product with explicit MB-Approval 345.0; Silkolene Titan CHF 11S lists that approval.
This is a fit for owners whose vehicle specifies CHF-11S and who value broad make coverage and a low-temperature pour point. Verify the required fluid specification for your Mercedes, since compatibility listings do not replace vehicle-specific requirements.

#6
6. Silkolene Titan CHF 11S
- Container Type: Bottle
- Form: Liquid
- Material: Synthetic
Best for: MB-Approval 345.0 seekers.
Why it ranks #6: This synthetic hydraulic oil lists MB-APPROVAL 345.0 among its specifications, an important match to verify against the exact Mercedes requirement.
Silkolene Titan CHF 11S lists MB-Approval 345.0, making that named approval its clearest differentiator for buyers checking Mercedes fluid requirements. Its synthetic hydraulic-oil formulation and compatibility with elastomers further identify the product’s stated system context, alongside a set of other manufacturer approvals and recommendations.
The product is described as synthetic high-performance hydraulic oil, and the listed MB-Approval 345.0 gives Mercedes buyers a specific approval to compare with their vehicle’s requirement. Compatibility with elastomers is also stated, a relevant material detail for a hydraulic-system fluid. Additional approvals and recommendations span manufacturers including Chrysler, PSA, ZF, VW, Bentley, BMW, and Porsche, offering broader reference information without replacing the need to match the exact specification required for the service.
- MB-Approval 345.0 listed
- Synthetic hydraulic oil
- Elastomer compatibility stated
- Multiple additional approvals and recommendations listed
- The supplied listing does not specify a bottle volume.
Skip it if you need a stated -76°F pour point and broad CHF-11S coverage; Triax Powerfluid 450 lists those details.
This suits Mercedes owners whose required fluid specification matches MB-Approval 345.0 and who want a synthetic hydraulic oil with stated elastomer compatibility. Check the exact vehicle requirement; the listing does not provide bottle volume.

#7
7. ATP AT-224 Synthetic
- Container Type: Bottle
- Form: Liquid
- Material: Synthetic
Best for: Cold-weather CHF applications.
Why it ranks #7: Its synthetic formula is described for all power steering systems, including specialty CHF and European applications, but the listing names no Mercedes-specific approval.
ATP AT-224 states fluidity down to -58°F and compatibility with specialty CHF/European applications, combining a concrete cold-weather figure with broad system coverage. Its synthetic formulation is also described as providing high shear stability and film strength, details aimed at severe-duty and high-temperature operating conditions.
ATP lists the fluid for all power-steering systems, including specialty CHF and European applications, making its use scope relevant to Mercedes owners checking fluid requirements. The synthetic formula’s stated high shear stability and film strength support its severe-duty and high-temperature positioning. Its -58°F fluidity claim addresses cold operation, while the 32-ounce bottle provides a defined quantity for service. The supplied information does not name a specific Mercedes approval, so the general compatibility statement should be checked against the required specification.
- Synthetic power steering fluid
- CHF and European applications included
- Fluidity listed down to -58°F
- High shear stability and film strength stated
- No specific Mercedes-Benz approval is named.
Skip it if you require a named Mercedes approval; Silkolene Titan CHF 11S lists MB-Approval 345.0.
This suits buyers seeking synthetic fluid for CHF or European applications, particularly where cold-weather fluidity and severe-duty properties matter. Mercedes owners should still match its broad application claims to the specific fluid specification required.

8. Febi-Bilstein Power Steering Fluid
- Container Type: Bottle
- Form: Liquid
Best for: One-liter service bottle.
Why it ranks #8: This is explicitly sold as power steering fluid in a one-liter bottle, but the supplied listing gives no Mercedes part number or fluid approval.
A one-liter bottle gives Febi-Bilstein Power Steering Fluid a practical quantity for buyers planning a steering-fluid service. The listing identifies it for steering-fluid use and supplies a liquid product in a bottle, while its named manufacturer provides a clear product identity for shoppers comparing routine service supplies.
Febi-Bilstein is identified as the manufacturer, and the product is listed for steering-fluid use, so buyers can distinguish it from general-purpose hydraulic oils. The one-liter quantity offers a defined amount for a planned service, and the bottle’s liquid form fits ordinary fluid handling. The supplied specifications do not name Mercedes-Benz applications or a fluid approval, however, so this listing alone cannot establish whether it matches a particular Mercedes steering system.
- One-liter quantity listed
- Identified for steering-fluid use
- Liquid form in a bottle
- Febi-Bilstein manufacturer specified
- No Mercedes-Benz application or fluid approval is provided in the listing.
Skip it if you require an explicit Mercedes application; Triax Powerfluid 450 names Mercedes-Benz compatibility and CHF-11S use.
Choose this if you need a one-liter bottle identified for steering-fluid service and have already established the required specification independently. Its listing does not establish Mercedes-Benz fit or an approval, so application matching remains essential.

9. Lubegard Complete Synthetic
- Container Type: Bottle
- Form: Oil
- Material: Synthetic
Best for: All-season system service.
Why it ranks #9: The synthetic fluid claims service use across European vehicles and electric hydraulic systems, but it does not list a Mercedes-specific specification or approval.
Lubegard’s synthetic fluid combines stated cold- and high-temperature performance with seal and hose protection, giving buyers a service option that addresses changing operating conditions. The listing covers European, North American, and Asian vehicles, and specifically notes Honda/Acura fluid as the exception to its broad application claim.
Lubegard says the fluid reduces friction and protects seals and hoses, connecting its formulation to power-steering-system protection. Its stated cold- and high-temperature performance addresses stiffness described as morning sickness, while the claimed ability to clean and free sticky turbines and pumps speaks to system maintenance. The listing also identifies electric hydraulic systems as a use case. For Mercedes buyers, its broad vehicle coverage is useful context, but the supplied information does not specify a particular Mercedes approval.
- Synthetic power steering fluid
- Seal and hose protection stated
- Cold- and high-temperature performance claimed
- Listed for electric hydraulic systems
- No specific Mercedes-Benz fluid approval is listed.
Skip it if you need an explicit Mercedes fluid approval; Silkolene Titan CHF 11S lists MB-Approval 345.0.
This is for buyers seeking a synthetic fluid with stated seal, hose, temperature, and pump-cleaning benefits across multiple vehicle regions. Mercedes owners should match the required fluid specification, since no Mercedes approval is named in the supplied details.

#10
10. BlueDevil Power Steering Fluid
- Container Type: Bottle
- Form: Liquid
- Material: Mineral Oil, Synthetic
Best for: Older systems with seal leaks.
Why it ranks #10: This mineral-oil and synthetic blend emphasizes stop-leak treatment rather than Mercedes fitment, and the listing gives no Mercedes-specific approval or compatibility.
BlueDevil combines power-steering fluid with a stop-leak additive that softens and conditions hardened seals and gaskets, directly addressing the leak issue described in its product information. The listing also claims wear and corrosion prevention and smoother steering operation, making seal conditioning its primary distinction from a standard refill fluid.
BlueDevil explains that older seals and gaskets can dry, harden, and shrink, then presents its additive as a way to soften and condition them to stop leaks. That makes the product’s central use case leak treatment rather than a specification-led Mercedes fluid match. The listing also claims help against wear and corrosion and smoother steering operation. It is a one-quart bottle containing mineral oil and synthetic materials, but no Mercedes approval is provided.
- Stop-leak additive included
- Seal and gasket conditioning stated
- Wear and corrosion prevention claimed
- One-quart bottle
- No Mercedes-Benz fluid approval or application is listed.
Skip it if you need a fluid with explicit Mercedes compatibility rather than stop-leak treatment; Triax Powerfluid 450 names Mercedes-Benz.
This is for owners considering a stop-leak treatment for hardened seals and gaskets, rather than a fluid selected by Mercedes approval. Match the vehicle’s required fluid specification before using it as a power-steering refill.

View on AmazonWhy a broad compatibility claim can mislead
A broad compatibility claim is not a substitute for matching the fluid specification printed for your Mercedes. These listings illustrate why: Mercedes-Benz Genuine OE 345.0 names a specific designation, Silkolene Titan CHF 11S lists MB-APPROVAL 345.0, and Triax names CHF-11S applications alongside Mercedes-Benz compatibility. Those details are more useful than a generic statement that a fluid works across vehicle makes, but they still do not prove that every Mercedes model uses that fluid.
The trap is assuming that all power steering or hydraulic fluids are interchangeable because they share a use category. A wrong match can create a service problem, and the product data here do not establish mixing compatibility, model-year coverage, or consequences for a particular car.
Check the owner’s manual or the vehicle’s fluid label, then compare the exact designation and part number before opening a bottle.
Stop-leak fluid is a different kind of choice
Stop-leak fluid is a treatment-oriented choice, not a replacement for confirming the required Mercedes fluid specification. BlueDevil describes its product as conditioning hardened seals and gaskets to address leaks, while the genuine Mercedes listings identify specific fluids or part numbers and the CHF products emphasize hydraulic-fluid applications. That is a meaningful trade-off: an owner confronting seepage may be drawn to a product that advertises leak treatment, but the listing does not show that it is approved for any Mercedes model.
Nor does the data establish whether a leak is caused by a seal, hose, or another fault. Treat the stop-leak claim as a separate feature, not proof of compatibility or a repair diagnosis.
First identify the fluid called for by the vehicle; if the system is losing fluid, investigate the cause rather than relying on an additive claim to resolve the underlying issue.
How to Choose Mercedes Power Steering Fluid
Match the specification or part number
Start by matching the exact specification or part number required by your Mercedes. The listings span Mercedes-Benz Genuine OE 345.0, genuine fluid 001-989-20-03-12, Q1460001 with a note that Q1460002 is the new part number, and hydraulic fluid 000 989 91 03 Silkolene Titan CHF 11S also lists MB-APPROVAL 345.0, while Triax specifies CHF-11S applications.
These identifiers are not interchangeable evidence: consult the vehicle manual or fluid label. Buyers with a confirmed 345.0 requirement can compare the genuine OE bottle with Titan’s listed approval; buyers with another part number should prioritize a matching genuine listing or verified equivalent.
Check the kind of application listed
Look for a product whose stated application matches the system and fluid requirement in your vehicle. The choices range from products identified as steering fluid, such as the Genuine Mercedes Q1460001 and Febi-Bilstein, to hydraulic-fluid products such as Mercedes-Benz 000 989 91 03 10 and Silkolene Titan CHF 11S. Triax and ATP specifically mention CHF-related applications, while Lubegard says it is suitable for electric hydraulic systems.
The listing for BlueDevil instead highlights stop-leak treatment. If your manual specifies a CHF fluid, favor a listing that states CHF compatibility; if it specifies a Mercedes part number, use that as the primary filter.
Broad application language is less decisive for a buyer without confirmed fitment.
Choose the bottle format you need
Check the listed container and amount against the service you plan to perform. Products in the set include one-liter bottles, such as Febi-Bilstein Power Steering Fluid and Mercedes-Benz Power Steering Fluid 345.0 Genuine OE, and quart-size listings such as Triax Powerfluid 450 and BlueDevil Power Steering Fluid. Lubegard and ATP each specify 32 fluid ounces.
The supplied specifications list bottles for the products that include container details, but they do not provide fill capacities for individual Mercedes models. A buyer topping up should avoid assuming a full bottle is required; a buyer performing a larger service can compare labeled quantities while consulting the vehicle’s service information for system capacity.
Which Power Steering Fluid Should I Choose?
Choose Mercedes-Benz Genuine OE 345.0 if your vehicle’s specified fluid is 345.0; its genuine OE identification makes it the leading match in this list. If your manual identifies part number 001-989-20-03-12 or its stated replacement, Mercedes-Benz Genuine 001-989-20-03-12 is the more relevant pick. For a vehicle calling for Q1460001/Q1460002, check Genuine Mercedes Q1460001 and confirm the updated number.
If the required specification is CHF-11S, compare Triax Powerfluid 450 with Silkolene Titan CHF 11S, which lists MB-APPROVAL 345.The Mercedes-Benz 000 989 91 03 10 bottle suits buyers who have confirmed that hydraulic-fluid part number.
Do not select BlueDevil Power Steering Fluid solely for its stop-leak claim; verify Mercedes compatibility first.
Related Buying Guides
Frequently Asked Questions
How can I find the correct power steering fluid specification for my Mercedes model?
Check your owner’s manual or service documentation for the exact fluid specification or Mercedes part number required for your vehicle. Match that requirement to the product listing, rather than relying on a broad compatibility claim. If the documentation is unclear or names a replacement part number, verify the match before filling the reservoir.
Can I mix different power steering fluids in a Mercedes reservoir?
Do not mix fluids unless you have confirmed that both meet the specification required for your vehicle. Similar descriptions or broad compatibility claims do not establish that fluids are interchangeable. Check the manual and product approvals first; if you cannot confirm compatibility, seek qualified guidance before topping up or changing the fluid.
What symptoms suggest the wrong fluid or a power steering leak?
New steering noise, increased steering effort, or visible fluid loss can signal a problem, though these symptoms do not identify its cause on their own. Check for leaks and confirm that the fluid matches the vehicle’s specified requirement. If symptoms persist or worsen, have the system assessed rather than adding an unverified fluid.
Which option should I compare if my Mercedes requires CHF-11S?
If your vehicle specifically calls for CHF-11S, compare TRIAX Powerfluid 450 with Titan CHF 11S and verify each listing against the required specification. The article identifies Silkolene Titan CHF 11S as listing MB-APPROVAL 345.0; do not assume that a product title alone confirms suitability for your vehicle.
What if my manual gives a Mercedes fluid part number instead of a specification?
Match the listed part number or its confirmed replacement before choosing a bottle. The article points buyers with requirement 001-989-20-03-12 to the corresponding genuine fluid, and those needing 000 989 91 03 10 to that bottle. For Q1460001/Q1460002, check Genuine Q1460001 and confirm the updated number.
Final Words
Start with the exact specification or part number in your Mercedes documentation. If it calls for 345.0, the Genuine OE 345.0 bottle is the clearest match in this list. For another named requirement, select the corresponding genuine bottle or verify an alternative’s listed approval.
Compare the CHF-11S options only when that fluid is specified, and do not choose a broad-compatibility or stop-leak product without confirming suitability.
