Cetane Improver

    Wynn's Diesel Power Boost is a Cetane improving formulation which raises the Cetane number of diesel reducing ignition delay resulting in more complete and consistent diesel combustion.
    Meets all NCWM, EMA, and TMC definitions for Premium Diesel as per (ASTM D613)
    -Early and continuous ignition of diesel delivers better combustion throughout the power stroke delivering greater torque and power.
    -Vastly improves cold starting and low temperature performance
    -Quietens diesel engine noise by reducing knock
    -More complete combustion leads to better fuel economy and reduced emissions.


    Absorbs and removes water from petrol and diesel fuel systems

    Wynn’s DRY FUEL is a product suitable for petrol or diesel engines developed to absorb water from the fuel system.
    Fuel is hygroscopic by nature meaning it attracts water from the atmosphere causing corrosion, micro-organism growth and poor engine operation.
    Dry Fuel emulsifies the free water into a stable fuel solution allowing it to be burned through combustion and out the exhaust as vapour without damage to the engine.


    LEAD SUBSTITUTE *Replaces the lead without harming the environment*

    An emission free, environmentally friendly, lead substitute solution to protect the older vehicle when running on unleaded petrol.
    Valve Guard will prevent valve seat recession, free sticky valves and lubricate the upper cylinder improving general performance.
    Valve Guard is compatible with normally aspirated as well as turbo charged vehicles and will not affect catalytic converters.
    200ml treats 50 litres unleaded petrol.

Why Additives?

Wynn’s additives are chemical treatments that prevent contamination of these essential fluids, and solve problems with your car.
Common problems such as black exhaust smoke, clogged injectors, blocked soot filter, high exhaust emissions, poor engine performance, excessive fuel consumption, leaks, and bad smells can all easily be solved or prevented by using Wynn’s additives.

More info about additives



Both modern cars and older vehicles have specific requirements, that have a chemical solution to provide the optimal engine performance and driving comfort. Modern fuel systems are highly tuned and therefore more susceptible to the negative effects of chemical reactions in the fuel. These lead to fouling of the fuel system, lack of lubrication, corrosion and other problems. Older vehicles experience problems to obtain the correct air/fuel ratio and combustion efficiency due to accumulation of deposits in the fuel system and wear on the components.

Wynn's, a 75 year long success


In 1939, Chestien Wynn, a 70 year old retired attorney with an interest in lubrication chemistry, discovered a formula he named “Wynn’s Friction Proofing” Oil. This surface treatment for metal actually changed the chemistry of the metal, making it softer and better able to withstand friction and wear.

Chestien would mix a batch of his product in his one car garage workshop, fill and label glass bottles with it and sell them to the local service stations and garages. Motorists, who used the products once, wanted another bottle of it. That was the foundation stone of Wynn Oil Company.
