Penrite HPSO (Honda Power Steering oil) is a full synthetic power steering oil designed specifically for use in Honda manufactured vehicles that require a different viscosity then conventional steering oils offer.

Penrite HPSO is compatible to mix with OEM Honda fluids, so ideal for top ups. The synthetic formula offers increased service life while also protecting components against rust and corrosion. Additives are also included to help prevent noise and shudder to increase steering performance as well as others that help to rejuvenate and swell seals to prevent oil leaks. Penrite HPSO is also suitable for use in some Ford Falcon AU-BF as well as FPV and Territory models as a high performance alternative where increased heat and load is applied.
