    Race Castor is an ashless SAE 20W-40 engine oil manufactured from high quality castor vegetable oil, synthetic ester, anti-corrosion additives and an advanced anti-oxidant. The synthetic base fluids are specially blended to produce SAE 30 and SAE 40 classifications. This helps to reduce or eliminate traditional problems such as lacquers and deposits and produces higher and stronger film strength, very high load carrying capacity, better wetting properties and reduced power loss due to friction.

    Racing Brake Fluid is ideal for brake systems in high performance on-road vehicles and in all types of cars, trucks and motorcycles involved in all forms of competition including rally and circuit racing.

    Race Coolant Inhibitor Concentrate is a non glycol based coolant that protects against corrosion, cavitation, scaling and oxidisation in vehicles that do not require an anti-freeze anti-boil coolant. It is an effective water wetting agent that uses a hybrid of organic mono/diacid technology and a conventional inhibitor to provide maximum protection against corrosion whilst providing superior heat transfer to significantly reduce engine operating temperature.

    ATF 33 is designed for use in older Ford transmissions and power steering systems wherever a Ford Type F fluid is recommended. It is also suitable for drag car transmissions where a non-friction modified fluid is required. Ideal for use in Turbo 350 and 400 transmissions and others that may require this type of fluid to improve power transfer without slippage.

    Octane Booster is a fuel treatment that will keep injectors and inlet valves clean and will also provide octane enhancement when used with either unleaded or Ethanol E10 based fuels.Each 375ml bottle of Penrite Octane Boost will increase the octane level number by up to 2.5 when mixed with 50 Litres of unleaded 91 (RON) Octane Petrol.
