How do I know if PROZONE^® Fuelsaver is suitable for my vehicle?

PROZONE^® Fuelsaver is suitable for all vehicles with internal combustion engines using gasoline (petrol) or diesel fuel. It can also be used with two-stroke engines. PROZONE^® Fuelsaver can be fitted to vehicles already in use, and to new vehicles.

When fitted to a vehicle using unleaded gasoline with a catalytic converter, PROZONE^® Fuelsaver provides the additional benefit of prolonging exhaust system and catalytic converter life.

PROZONE^® Fuelsaver units are available in 5 sizes to suit different engine capacities, as shown in the table below. The final digit in the model number indicates the number of alloy cores within each unit,ie. the FS4 contains four alloy cores:-

Vehicle Type	Engine Capacity	Unit/model number
motorcycles, etc	up to 1,000cc	FS1
cars & vans	1,000 to 5,000cc	FS2
medium trucks & buses	5,000 to 10,000cc	FS3
heavy trucks & buses	10,000 to 35,000cc	FS4
ships and locomotives.	above 35,000cc ++	FS5

PROZONE^® Fuelsaver consists of an in-line flow-through chamber which is fitted to your vehicle's fuel line within the engine compartment. Installation of PROZONE^® Fuelsaver, as close to your vehicle's carburetor or fuel injection pump as possible (see below), can be carried out by any practical motorist or by a qualified mechanic or trained automotive technician, and usually takes less than an hour to complete.

After PROZONE^® Fuelsaver has been fitted, drivers of gasoline-engined vehicles should quickly be aware of an improvement in engine performance.

Drivers of vehicles with carburetors should drive for a further 2,000 to 3,000 miles (3,600 to 5,400 kilometers) before re-tuning the engine for maximum performance.

Drivers of diesel-engined vehicles should notice a gradual improvement in fuel economy and engine performance together with a reduction in smoke emissions and diesel knock over a period of several months until optimum operating conditions are reached.

Once installed, PROZONE^® Fuelsaver will continue working for more than 150,000 miles (240,000 kilometers), and exhaust system and catalytic converter life will be prolonged as less corrosive gases now pass through them.

Yes. Comparative before-and-after independent performance tests of PROZONE^® Fuelsaver have been carried out over the past eight years by a variety of organizations in more than a dozen different countries. These organizations fall into three categories:

1) academic and training institutes with specialized facilities for testing automobiles and automotive accessories
2) organizations with specialist experience of certain types of engines and vehicles
3) companies and individuals who have tested PROZONE^® Fuelsaver under the practical conditions relative to their own fields of expertise.
Extracts from many of these tests together with testimonials from satisfied customers are given in the pages of Worldwide Test Results and Testimonials.

Many motorists are being forced to switch to unleaded gasoline (ULG) as governments around the world ban the sale of leaded gasoline. Drivers, particularly of older vehicles, have expressed concern that ULG may have a detrimental effect on their vehicle's engine.

Although most modern cars can use ULG, many engines need adjustment to prevent pinking or pre-ignition, and to ensure smooth running.

Motorists switching to ULG are worried that adjusting their car engines to use this environmentally friendly fuel may actually result in less engine power and higher fuel consumption, especially under acceleration conditions

PROZONE^® Fuelsaver enhances the combustibility of the fuel and improves power output and fuel economy. The result is equivalent to an increase in the octane number of the fuel, and enables engines already running on ULG to use the fuel without adverse effects.

Engines previously adjusted to use ULG can now be re-tuned back to manufacturers' specifications for leaded fuel performance while using unleaded gasoline.

Did you know that in a single year the average motor car produces almost 11,000 lbs of Carbon Dioxide (CO2), 120 lbs of Nitrogen Oxides (NOx), several lbs of Sulfur Dioxide (SO2) and significant quantities of other very harmful pollutants, including Carbon Monoxide (CO), Hydrocarbons (HC) and Volatile Organic Compounds (VOCs)

Although Carbon Dioxide (CO2) does not directly affect human health, it is the main contributor to the "greenhouse effect" which increases global warming.

Oxides of nitrogen (NOx) are produced as a result of the very high engine operating temperatures typically encountered when the vehicle is stationary or moving slowly in traffic. In the presence of VOC's and strong sunlight, oxides of nitrogen form ground-level ozone, a major component of the traffic smog which can damage lung tissue and aggravate respiratory diseases. The picture below shows typical "ozone" traffic smog. When we talk about being ozone-friendly, we don't mean that we are friendly towards ozone on the ground; we are referring to stratospheric ozone or the so-called ozone layer. To find out the difference, please go to our Ozone Friendly Page.

Carbon monoxide (CO) is lethal in confined spaces, initially inducing drowsiness and subsequently causing death when inhaled. Carbon monoxide is formed when there is insufficient oxygen present to ensure complete combustion of the fuel. It is particularly dangerous to people who smoke or who have anemia or heart disease.

Medical reports have linked the formation of cancer and other diseases to hydrocarbon particulates. Hydrocarbons (HC) are particles of carbon soot emitted through the exhaust system as a result of incomplete combustion. They can cause damage to lung tissue and cardiovascular disease. Children and the elderly are at highest risk from the particulate matter emitted by motor vehicles.

Sulfur Dioxide (SO2) is a factor in the production of "acid rain" which acidifies soil and water, killing plant and animal life. It also causes corrosive damage to buildings and is known to aggravate respiratory conditions such as asthma and chronic bronchitis. The information for this section on the damage caused by vehicle emissions is taken from Environmental Defence, an excellent website devoted to informing the public on health and environmental issues.· Go to their site to find out How Much Your Vehicle Pollutes.

As can be seen in our Gas Emissions graph, PROZONE^® Fuelsaver makes a significant contribution towards reducing the levels of all of the above pollutants.

Although PROZONE^® Fuelsaver in its present form was patented as recently as 1995, the history of the development of the underlying technology can be traced back to World War II.

At that time British Royal Air Force fighter aircraft were sent to the Russian front, but were unable to operate efficiently on the low octane fuel available. To solve the problem, scientists and engineers prepared a fuel catalyst to act as an octane booster and to improve the combustibility of the fuel.

Later, the original fuel catalyst was improved upon and additional technology incorporated to form the PROZONE^® Fuelsaver we know today. Now the British company Fuelsaver Overseas Limited manufactures PROZONE^® Fuelsaver and holds worldwide patent rights. An outline of the history of the fuelsaver technology can be found at the website of the International Tin Research Institute at www.itri.co.uk/fcats.htm
