Motul Multi HF is a dedicated high performance synthetic hydraulic fluid, designed for a multitude of uses including modern power steering systems, hydraulic suspension, SMG transmission, and hydraulic hard top systems commonly found on prestige vehicles. Synthetic hydraulic fluids are superior to traditional hydraulic fluids as they help in the reduction of heat generation, providing improved longevity of components and retaining consistent viscosity across operating temperatures. Motul's Multi HF is formulated specifically to protect hydraulic systems under heavy load conditions, providing noise reduction (particularly in cold conditions), and features anti-wear, anti-corrosion, and anti-foaming properties that aren't found in typical automatic transmission fluids. If your vehicle specifies a CHF 11S fluid be used, we recommend Motul's synthetic Multi HF.
