Fuel Stabilizer

Wynn's Fuel Stabilizer is an additive for petrol and diesel engines to preserve the fuel when the engine is put out of service during a long time or when the fuel has to remain in the tank during a long time, e.g. petrol in case of LPG engines.

  • Prevents the degradation of the fuel in the tank when the engine is put out of service for several months.
  • Protects the fuel against oxidation.
  • Prevents deposit formation in the tank and filter caused by oxidation products.
  • Eases starting-up of the engine after a period of extended shutdown.
  • Keeps the fuel system clean.
  • Protects the engine parts against rust and corrosion.
  • Specially recommended for vehicles equipped with LPG system.


Especially recommended before a period of extended shutdown of the engine and to avoid starting problems after this period.
For all types of petrol, LPG and diesel engines, 2 and 4 stroke, in- or outboard marine engines, vehicles, lawn mowers, stationary engines.
When the fuel remains in the tank during a long time (petrol tanks of LPG engines).
When the vehicle is rarely used (less than one topping-up a month).
Also specially recommended for classic cars.


Add to the petrol or diesel fuel tank before any period of extended shutdown.
1 litre treats 200 litres of petrol or diesel fuel.

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.
