One Shot Concentrated Fuel System Cleaner (200mL)
Fuel system service as you drive to maximise efficiency
This powerful, technologically advanced additive works as you drive to provide intake system clean-up, emission control, extend component life and more efficient fuel utilisation. One Shot Concentrated Fuel System Cleaner is for unleaded and lead replacement petrol, turbo charged, fuel injected and carburetted 2 & 4 stroke engines. This advanced formulation has been designed to provide maximum efficiency as a fuel additive as it contains the most advanced active chemical compounds that are the most advanced petroleum additives that have been developed during the past 25 years. Safely clean your engine’s fuel system componentry and restore lost compression and performance with the help of One Shot.
A special feature of the One Shot Concentrated Fuel System Cleaner is that it incorporates a very advanced formulation containing the most expensive ingredients to provide maximum efficiency, as far as a petrol additive is concerned. Not only does it provide all the features that we have come to expect from PT5 Plus Petrol Treatment, it can also provide these more quickly. The Polybutane Ashless Lubricant formulation this product contains can coat the entire fuel system and combustion chamber/s, to minimise the accumulation of future detrimental deposits in these areas. This will maintain optimum performance for longer periods before deterioration commences.
The recommended dosage is one bottle (200mL) up to 60 litres of fuel. This quantity will suit most passenger vehicles. The dosage can be adjusted, in proportion, for petrol tanks with significantly differing volumes. For maximum benefit, re-treat the petrol tank with One Shot Concentrated Fuel System Cleaner every 2,500km or 50 hours of operation. Not for use in diesel engines.
The additives package is designed for use as a ‘one-shot clean-up’ and can be used again at the fourth tank refill. Alternatively add PT5 Plus Petrol Treatment at each tank refill, at the recommended dosage to maintain fuel system, engine cleanliness and performance. With fuel injected engines, do not run the fuel tank dry. Our Manufacturer has conducted extensive testing with both American and Foreign manufactured vehicles, and a number of tests have been carried out in Australia with a range of local petrols.
One Shot Concentrated Fuel System Cleaner is suitable for use in all types of petrol engines (do not use in diesel engines). The 200 mL bottle has an extended neck, to enable the spring-loaded flap to be opened easily in filler necks designed for Unleaded Petrol.
Remove the cap and insert the bottle fully into the tank, and add the total contents of the bottle. Remove the bottle and discard. Then fill the tank to the automatic shut-off level and operate the vehicle or equipment normally. The product works as you drive.

Anything else you
need to
know?
One Shot Concentrated Fuel System Cleaner is a balanced compound of ashless organic materials in a pure hydrocarbon solvent, containing:
- A surfactant that breaks the surface tension of water in the fuel, so that it can pass harmlessly through with the fuel, and be disposed of as steam through the combustion process.
- A detergent that helps clean the entire fuel system, combustion chambers and exhaust system.
- A top oil that lubricates the fuel pump, injectors, valves and upper cylinder area.
- A residual ingredient, that places a minute coating on the fuel injectors and combustion chamber components, to retard deposit accumulation.
- An octane enhancer that reduces the octane requirement of the engine.
- A non-metallic combustion modifier that smooths the combustion process and reduces exhaust emissions.
This product contains Petroleum Distillates. Do NOT store near heat, sparks or flame. Wash with soap and water if this product contacts skin. KEEP OUT OF REACH OF CHILDREN. A Material Safety Data Sheet is available from Pro-Ma Systems.
Combustible. Contains petroleum distillates. Harmful or fatal if swallowed. If swallowed Do NOT induce vomiting. Call a doctor immediately
NOTE: ONE SHOT CONCENTRATED FUEL SYSTEM CLEANER CONTAINS NO METHANOL, ETHANOL OR ISOPROPANOL ALCOHOLS.
