Triax Power Steering Fluid CHF 11S — 1 Quart Fully Synthetic Long-Life Formula for European Cars

TRIAX Powerfluid 450 PSF CHF 11S is a long-life, fully synthetic hydraulic and power steering fluid designed to match or exceed OEM CHF 11S specifications for European, American, and many Asian vehicles.

This fluid is formulated from PAO and ester base stocks with high-performance additives to deliver stable viscosity across a wide temperature range, excellent shear resistance, and compatibility with a broad set of hydraulic and power steering systems. It's intended as a drop-in replacement where manufacturers call for CHF 11S, CHF 202, CHF 7.1, or the listed OEM part numbers, providing smooth steering, reliable hydraulic actuation, and protection for seals and pumps.

Will this fluid work in my European car’s power steering?

Yes — TRIAX Powerfluid 450 PSF meets or replaces many European OEM fluid designations and is engineered for modern systems. It is compatible with Bentley, Audi, BMW, Mercedes-Benz, Porsche, VW and other Euro brands that specify CHF 11S or listed equivalents.

• Replaces Pentosin CHF 11S, CHF 202, CHF 7.1 equivalents.
• Meets Audi/VW G002000 and G002012 cross-references.
• Formulated for self-leveling suspensions and hydraulic convertible tops.
• Designed to preserve seals and pump longevity in Euro systems.

How does it perform across extreme temperatures?

This synthetic formula is optimized for both arctic starts and high-heat operation, maintaining viscosity stability so steering feel and hydraulic response stay consistent. It resists thickening in winter and thinning in summer, reducing sluggish or "lazy" steering sensations.

• Arctic-grade pour point down to -76°F for cold starts.
• Stable use temperatures up to 266°F for hot environments.
• Zero shear formulation preserves viscosity under stress.
• Helps maintain consistent hydraulic response across seasons.

What vehicle systems and functions can this fluid be used for?

Beyond conventional power steering racks and pumps, this fluid suits a wide range of hydraulic functions found on modern vehicles, including suspensions and hydraulic actuators. It's compatible with electrical and hydraulic power steering, central locking hydraulics, shock absorbers and other vehicle hydraulic circuits that specify compatible chemistry.

• Hydraulic power steering pumps and racks (hydraulic & electric-assist).
• Self-leveling and hydro-pneumatic suspensions.
• Convertible top actuators, central locks, and tractor control systems.
• Shock absorber hydraulic systems and other OEM-specified circuits.

Which OEM part numbers and fluid types does it replace?

TRIAX Powerfluid 450 PSF is formulated to replace many manufacturer fluid codes and aftermarket references, making it straightforward to select when an exact OEM product is needed. Check your vehicle manual or service literature to confirm the listed cross-references match your specification.

• Pentosin CHF 11S, CHF 202, CHF 7.1 cross-replacements.
• Audi / VW G002000, G002012 and Bentley RH 5000 equivalents.
• BMW/Mini part numbers and Mercedes-Benz 236.3 references.
• Also compatible with Chrysler, Ford, GM, Hyundai/Kia, Toyota and Volvo listed specs.

Who is this for: drivers, technicians, and fleet managers who need a durable, all-season synthetic hydraulic and power steering fluid that aligns with European CHF-level specifications and many OEM cross-references. It is useful for owners of European luxury cars, older vehicles requiring CHF-type fluids, workshops servicing mixed-brand fleets, and anyone who wants improved steering feel and hydraulic reliability in extreme temperatures. Always verify the required specification in your vehicle’s service manual before replacing fluids.
