Penrite HPSO is a fully synthetic oil specially formulated for use in power steering and suspension units. It contains specialised synthetic base oil and a unique combination of dispersants, anti-shudder additives, and seal swell additives to offer long service life, minimisation of viscosity loss and maximum wear protection.
HPSO is primarily designed and recommended for use in the power steering units of all Honda motor vehicles as well as Rover models 416i, 825 and 827 that use Honda power steering components. It may also be used in high performance applications in other vehicles such as Ford Tickford series, AU, BA & BF XR, FPV & Territory SX-SY series vehicles. The synthetic base oils and higher viscosity help to reduce pump wear and maintain steering feel where extra heat and load is expected in these applications. HPSO is also suitable for use in motorcycle forks where SAE Grade 20 oil is specified by the manufacturer.
