Modern steering, suspension, and stability systems rely on highly engineered hydraulic fluids to operate correctly. In many applications, what’s commonly referred to as power steering fluid is actually a specialized central hydraulic fluid like Pentosin CHF 11S.
Pentosin CHF 11S is a synthetic, high-performance hydraulic fluid engineered for lifetime use in demanding automotive systems. Designed to maintain stable performance from cold starts at -40°C to high operating temperatures exceeding 130°C, it delivers consistent hydraulic response under extreme conditions.
In this episode of Inside the Brands, we explain:
– What central hydraulic fluid is
– Why viscosity index and thermal stability matter
– Where CHF 11S is commonly specified
– Why using the correct OE-approved fluid prevents costly system damage
With over two decades of OE use, CHF 11S remains widely specified for modern power steering systems, hydro-pneumatic suspension, level control, and stability systems. It is commonly used in Mercedes-Benz ABC suspension systems and power steering applications in many Volkswagen, Audi, BMW, and Volvo vehicles.
Whether you refer to it as power steering fluid or central hydraulic fluid, using the correct OE-approved product is critical to system performance, durability, and avoiding repeat repairs. Watch now!
