Fuel Catalysts are a simple effective route to improved fuel efficiency.
What If A Simple Inexpensive Device Would Allow Any Engine(s) You Operate To Run More Efficiently Resulting In Extra Power And Less Emissions?
This is what products known as fuel catalysts achieve.
And yet, despite decades of tests and endorsements by scientists and engineers, together with extensive real-world evidence, remarkably few people know about them.
This website attempts to change that…
fuelcatalyst.co.uk is the only website where you’ll find the truth, the whole truth, and nothing but the incredible truth about fuel catalysts.
And where you can purchase fuel catalysts that are as effective as any and priced to ‘pay for themselves’ over and over and over again across a huge range of applications.

Q. What are fuel catalysts?
A. These are fuel catalysts. They are simple inexpensive devices that exert beneficial effects on fuel by modifying its chemical properties.
Most often they are fitted in fuel tanks but they can also be fitted in cylinders that are then installed in fuel supply lines between the fuel tank and the engine.
Either way they last for at least 10 years or 100,000 miles and often much more to provide benefits that become ever more valuable as time passes.
Q. What are the benefits of fuel catalysts and what is the evidence?
A. The evidence in favour of fuel catalysts includes controlled tests at government accredited laboratories through to use by the US military and far, far more besides.
And the benefits according to the evidence are:
Fuel catalysts offer clear cut and hugely valuable improvements in the great majority of circumstances. But nothing works everywhere and Part 2 of BENEFITS & EVIDENCE explains the situations (there are not many) in which fitting fuel catalysts is not worthwhile.

Benefits & Evidence
The BENEFITS & EVIDENCE section of this website shows a representative summary and this is expanded upon in the FUELSPIRACY! special report that is a free download from this Fuelspiracy! section.
Buy fuel catalysts
Fuel catalysts have been giving impressive results for many decades, and fuel catalysts from this website feature enhancements that often give even better results, and faster.
Fuel catalysts are priced for multiple returns on investment for equipment from garden machinery through to heavy industrial.
For example costs of fuel catalysts to give year after year of improved fuel efficiency with extra power and less pollution and a host of other valuable benefits besides in:
Small engines up to 250cc – £14.95
Cars up to 1,500cc – £47.80
Small trucks up to 6,000cc – £119.60 and so on.
(Prices include VAT but exclude delivery, and discounts are available for larger quantities)

Q. How do fuel catalysts work?
A. Fuel catalysts are heterogeneous catalysts that cause beneficial chemical changes of fuel.
Among the changes are the breaking down of clusters of fuel molecules into smaller clusters, thereby allowing increased bonding with oxygen molecules. This is similar to blowing increased air (i.e. increased oxygen) on to a coal or wood fire to instantly generate more useful energy.
Further information about this topic is in the Fuelspiracy! special report that is available as a free download from the Fuelspiracy! section of this website.
Q. Are fuel catalysts easy to fit?
A. Usually fitting fuel catalysts is very easy… for most motorcycles, trucks, outboard engines and many other applications, including many cars, fitting is as simple as placing the catalyst(s) in the fuel tank.
But… there are exceptions including some modern cars where professional fitting will be required although the procedure is most often straightforward for a competent mechanic.

And the most obvious question of all: “If fuel catalysts are valuable to consumers and public health, then why do so few people know about them?
Our answer is that the truth about fuel catalysts has been suppressed in a cover-up that began decades ago and has continued ever since because when people use fuel catalysts both oil AND motor profits are dramatically reduced.
The history and supporting evidence for this claim are examined in a special report called Fuelspiracy!
