Independent laboratory tests have proven that CATACLEAN will reduce exhaust emissions by up to 60%.

Cataclean is a patented technology that effectively cleans and rejuvenates gasoline, diesel and flex fuel engines of any size, make or model. Formulated to meet the strictest global environmental regulations, Cataclean detoxifies and dissolves resin; gum and carbon build up in the injectors, valves, oxygen sensors and catalytic converter. It has been globally tested under strict laboratory conditions and in a wide cross-section of vehicles and engines over the last eight years.

CATACLEAN has proven itself as the most effective way to:
• Significantly reduce harmful exhaust emissions
• Improve fuel economy and reduce costly repair bills
• Improve overall engine performance
Prolong the life of your engine





CATACLEAN is NOT a fuel additive!, and it is not added to fuel as a gasoline or diesel "enhancement." Cataclean is only required every 3 months...not every time you fill your tank.

CATACLEAN is an engine and fuel system detoxification technology, developed to exceed the most recent environmental standards.

CATACLEAN rapidly and thoroughly dissolves resin, gum, carbon and similar deposits in the fuel system, oxygen sensor/lambda probe and catalytic converter.

CATACLEAN not only prevents fouling of your catalytic converter, it removes existing deposits and increases fuel efficiency.

CATACLEAN uses only third party, independent laboratory testing substantiate these claims.


Fouling, especially soot and carbon build-up, not only reduces engine performance, but it can also have serious (and almost always expensive) consequences.

The injection system becomes fouled not only by deposits in the fuel tank, but also by the crankcase breather, air filter contamination, blocked injectors and carbonated valves.

A fouled engine causes harmful gas emissions (in the case of gasoline engines) and soot emissions (in diesel engines). These contaminated exhaust emissions may also explain why your vehicle's catalytic converter is not functioning optimally....resulting in a serious loss of fuel efficiency.

This directly impacts the fuel delivery system, which can cause a fluctuating lambda signal, and/or error codes in the engine management system. In this situation it becomes almost impossible to achieve a correct air-fuel ratio. This in turn can cause expensive damage to the catalytic converter.

CATACLEAN addresses these problems by cleaning the fuel system, valves, pistons and catalytic converter, thereby increasing fuel efficiency and reducing emissions, ensuring optimal engine performance.


Catalytic converters are fitted to both gasoline and diesel engines and contribute to the reduction of harmful exhaust gases, such as hydrocarbon (HC) and carbon monoxide (CO).

The exhaust gases pass through a honeycomb brick, which is coated with noble metals (i.e., platinum, palladium and/or rhodium), which convert undesirable hydrocarbons and carbon monoxide to carbon dioxide and water, and nitrogen oxides to nitrogen and water.

Faulty combustion can cause extensive damage to the catalytic converter. This is why it is important that the engine run efficiently and the air-fuel ratio mixture is in the correct proportions.

When the catalytic converter is clogged and the surface becomes coated with carbon deposits, it is not able to efficiently convert exhaust gases. In extreme cases, the exhaust gases are so restricted that they try to pass by either side of the honeycomb brick, causing it to break apart. Then the catalytic converter must be replaced a very expensive repair.

Automobiles and Carbon Monoxide

What is Carbon Monoxide? Carbon monoxide (CO) is a colorless, odorless, poisonous gas. A product of incomplete burning of hydrocarbon-based fuels, carbon monoxide consists of a carbon atom and an oxygen atom linked together.

Why is Carbon Monoxide a Public Health Problem?

Carbon monoxide enters the bloodstream through the lungs and forms carboxyhemoglobin, a compound that inhibits the blood's capacity to carry oxygen to organs and tissues. Persons with heart disease are especially sensitive to carbon monoxide poisoning and may experience chest pain if they breathe the gas while exercising. Infants, the elderly, and individuals with respiratory diseases are also particularly sensitive. Carbon monoxide can affect healthy individuals, impairing exercise capacity, visual perception, manual dexterity, learning functions, and the ability to perform complex tasks.

Even as long ago as 1992,carbon monoxide levels exceeded the Federal air quality standard in 20 U.S. cities, home to more than 14 million people.

How is Carbon Monoxide Formed?

Carbon monoxide results from incomplete combustion of fuel and is emitted directly from vehicle tailpipes. Incomplete combustion is most likely to occur at low air-to-fuel ratios in the engine. These conditions are common during vehicle start-up when air supply is restricted ("choked"), when cars are not tuned properly, and at altitude, where "thin" air effectively reduces the amount of oxygen available for combustion (except in cars that are designed or adjusted to compensate for altitude).

Nationwide, two-thirds of carbon monoxide emissions come from transportation sources, with the largest contribution coming from highway motor vehicles. In urban areas, the motor vehicle contribution to carbon monoxide pollution can exceed 90 percent.

Automobile Emissions: An Overview

Cars and Pollution
Emissions from an individual car are generally low, relative to the smokestack image many people associate with air pollution. But in many cities across the country, the personal automobile is the single greatest polluter, as emissions from millions of vehicles on the road add up. Driving a private car is probably a typical citizen's most "polluting" daily activity.

Sources of Auto Emissions
The power to move a car comes from burning fuel in an engine. Pollution from cars comes from by-products of this combustion process (exhaust) and from evaporation of the fuel itself.

The Combustion Process
Gasoline and diesel fuels are mixtures of hydrocarbons, compounds which contain hydrogen and carbon atoms. In a "perfect" engine, oxygen in the air would convert all the hydrogen in the fuel to water and all the carbon in the fuel to carbon dioxide. Nitrogen in the air would remain unaffected. In reality, the combustion process cannot be "perfect," and automotive engines emit several types of pollutants.

"Perfect" Combustion
FUEL (hydrocarbons) + AIR (oxygen and nitrogen) CARBON DIOXIDE + water + unaffected nitrogen

Typical Engine Combustion

Exhaust Pollutants

Hydrocarbon emissions result when fuel molecules in the engine do not burn or burn only partially. Hydrocarbons react in the presence of nitrogen oxides and sunlight to form ground-level ozone, a major component of smog. Ozone irritates the eyes, damages the lungs, and aggravates respiratory problems. It is our most widespread and intractable urban air pollution problem. A number of exhaust hydrocarbons are also toxic, with the potential to cause cancer.

Under the high pressure and temperature conditions in an engine, nitrogen and oxygen atoms in the air react to form various nitrogen oxides, collectively known as NOx. Nitrogen oxides, like hydrocarbons, are precursors to the formation of ozone. They also contribute to the formation of acid rain.

Carbon monoxide (CO) is a product of incomplete combustion and occurs when carbon in the fuel is partially oxidized rather than fully oxidized to carbon dioxide (CO). Carbon monoxide reduces the flow of oxygen in the bloodstream and is particularly dangerous to persons with heart disease.

In recent years, the U.S. Environmental Protection Agency (EPA) has started to view carbon dioxide, a product of "perfect" combustion, as a pollution concern. Carbon dioxide does not directly impair human health, but it is a "greenhouse gas" that traps the earth's heat and contributes to the potential for global warming

Frequently Asked Questions About CATACLEAN

Is Cataclean safe for my car?

Yes. Cataclean has been extensively tested over the last 10 years by Industry Experts and is safe for use in both diesel and gasoline engines.

How is Cataclean different from other products on the market?

Cataclean is a superior cleansing agent and does not alter the fuel, whether gasoline, flex, or diesel in any way. It is specifically designed and formulated to "detoxify" the internal components of the engine and clean the oxygen sensors and the catalytic converter thus reducing the carbon footprint of your vehicle and improving overall performance.

Why are there no testimonials from users of the Cataclean product?

Cataclean relies heavily on audited independent laboratories to substantiate our claims. Any product can produce a personal testimonial but only Cataclean stakes our name and reputation on factual evidence that our product works!

How often do I use Cataclean?

It is recommended that one bottle of Cataclean (16.5 fluid ounces) is applied once every three months. A good rule of thumb is that if the performance of your vehicle begins to subside and fuel efficiency declines, then add a bottle of Cataclean.

What are some of the things that I should look for that would indicate that my vehicle is not operating at its best?

Your "check engine" or "service engine" light has come on.
Your MPG (miles per gallon) has declined below the EPA recommended range (i.e. 17 city/21 highway).
Your engine is sluggish.
You may fail your "emissions test".

Cataclean sounds wonderful. Are there other things that I can do to improve the performance of my vehicle?

Yes. Be sure that your tires are properly inflated to the right pressure level (found on the inside column of your door).
Change your oil regularly as advised by your mechanic.
Drive as consistently as possible and avoid "jack rabbit starts".
Use Cruise Control when on the highway (not in the rain though as this can cause hydroplaning). Don't let your engine idle for long periods of time as this increases emissions and wastes fuel (as much as _ mile per gallon).
Reduce the extra weight in your car.
