Tin-antimony alloy eliminates carbon deposits and keeps engines permanently clean and efficient - that's why the manufacturers don't use it

All over the world hundreds of millions of vehicles suffer the same common engine and exhaust system problems, whilst pumping vast amounts of excess exhaust emissions into the air we breathe. But all the problems, which are a money spinner for the motor industry, are completely avoidable.

In 1942, the American motor industry discovered the tin-antimony alloy pellets, which had been used in the fuel tanks of Hurricane fighter planes on the Russian front, triggered a reaction petrol and diesel fuels. This reaction caused the fuel to act as a self-cleaner as it combusted, keeping any engine permanently clean and efficient. They were very worried. This could devastate their profits from spare parts, expensive repairs and annual engine de-cokes. And even slow new car sales. But for the fuel additive companies the news was disastrous! So with help from their powerful friends, they started a smear campaign. And motoring's biggest lie was born. 

Along with misleading press and snake oil propaganda, the opening storyline of the 1943 Laurel & Hardy film, Jitterbugs, featured a travelling conman selling little wonder gasoline pills. The 'pills' were claimed to turn water into high-grade fuel but actually made customer's car engines to explode! In addition to stories of engine damage, the rather plausible sounding slogan, 'if they were that good the manufacturers would fit them' was widely circulated through garages and dealer networks. As with all well-organised propaganda, it didn't take long to spread. With ordinary drivers doing the industry's dirty work and repeating the lies that had been circulated to fool them. Over the last 80-years, motoring's biggest lie has been repeatedly used so many times, especially in the UK, many have come to believe it. 

Avoidable carbon deposits earn billions for the motor industry - but its long been simple to keep petrol and diesel engines permanently clean

The effectiveness of tin-antimony alloy in eliminating deposits from petrol & diesel engines has always been easily measured and observed using industry-standard before & after emissions results. In exactly the same way the big-brand fuel additives are evaluated. When engine deposits are removed a measurable reduction in toxic exhaust emissions can be observed as the engine becomes progressively cleaner. Along with before & after emissions results and MOT emissions certification, FTC has also been independently verified using PEMS (portable emissions measurement system) the advanced real-world measurement technology.

Tin-antimony alloy catalysts were first used in the 1960s in South Africa, to keep the engines in the heavy underground mining equipment belonging to the Anglo American Mining Company, permanently clean. They were so successful they were then used in the container ships owned by the South African Marine Corporation, to extend service intervals, reduce black smoke and prevent fuel wastage. For the last 60-years, tin-antimony alloy has been used by sharp-witted commercial and domestic vehicle owners all over the world. Whether old or new, petrol or diesel, FTC tin-antimony catalysts are used and recommended by the savvy owners of every imaginable make, model, type and age of vehicle. From Minis to Mercs, HGVs to JCBs from Land Rovers to Lamborghinis. And everything in between.

Despite the continuous repetition of the motor industry's 1940s snake oil propaganda slogans, intentionally misleading reviews and false claims made by many sellers, the truth remains. Tin-antimony alloy has only ever repeatedly demonstrated the single ability to permanently eliminate carbon deposits from petrol and diesel engines. Because that's all it does. Nothing else.

For the last 60-years, tin-antimony alloy has been used by sharp-witted commercial and domestic vehicle owners all over the world

For over forty years, modern vehicles have been equipped with engine control units ECU and fuel injection systems. The ECU uses information from a range of engine sensors to deal with the many problems engine deposits cause. Constantly adjusting and retarding the engines timing to prevent overheating, engine knock, running on and pinking. With the ECU hiding all the problems, its not surprising the first we know of hidden deposits is when dashboard warning lights start flashing, our engine goes into limp mode or another deposit related problem occurs such as a blocked fuel injector/s, misfire/s or sticking valve/s.

As carbon deposits build up on fuel injectors the ECU adjusts the injector pulse width to compensate; keeping the injectors open for longer to increase the fuel flow. This over fuelling increases carbon build-up on intake valves which in turn restricts air flow and prevents the valves from closing/seating properly - resulting in loss of compression. Partially burnt fuel vapour then escapes during combustion which both increases emissions and becomes carbonised throughout the entire exhaust system. Leading to the numerous problems millions of drivers suffer with fuel-heavy soot formations blocking the EGR, DPF and CAT. Leading to more flashing dashboard warning lights, more visits to the garage and yet more expense for the vehicles owner. 

Removing hidden deposits from combustion chambers, piston crowns and intake valves reduces the engines operating temperature and allows the ECU (where applicable) to progressively restore the engine's original timing and fuel trim settings. In new or clean engines tin-antimony catalysts will simply prevent deposits from forming in the first place, which simply means performance, economy and emissions will all remain largely unchanged.

The simple, low-cost, permanent solution for petrol and diesel vehicles

The Handbook of Air Pollution from Internal Combustion Engines confirms the many ways in which carbon deposits affect all internal combustion engines. Detailing loss of power, driveability issues, poor fuel economy and excess exhaust emissions. The Worldwide Fuel Charter clearly states that even the use of high quality fuel leads to deposit formation, affecting performance and leading to increased engine-out emissions. This helps explain why record numbers of relatively young vehicles fail the MOT emissions test every year. Data from the Driver & Vehicle Standards Agency (DVSA) confirms 1,273,771 vehicles were taken off the road in 2019/20. With 849,537 petrol engined and 430,527 diesel engined vehicles failing the MOT emissions test due to carbon deposits.

The emissions from engines with avoidable deposits contain raised levels of CO carbon monoxide, HC hydrocarbon emissions, PM2.5 / PM10 particulate matter, VOCs volatile organic compounds and NOx nitrogen oxides. Extensive data from the World Health Organisation (WHO), the European Environmental Authority (EEA) and the Royal College of Physicians confirm the staggering scale of the problem. WHO figures confirm 4,200,000 people die prematurely every year due to external air pollution. With EEA figures showing 400,000 lives are cut shorty annually in Europe - with 40,000 premature deaths in the UK blamed on toxic air pollution. With 90% of the worlds urban residents needlessly living with air pollution that far exceeds WHO safe guidelines. 

The discovery in 1942, that placing tin-antimony alloy in the fuel tanks of petrol and diesel vehicles permanently eliminated carbon deposits, should have revolutionised motoring. It should have saved drivers a fortune, saved precious resources and prevented the excess traffic pollution that blights the air for millions of people in towns and cities worldwide. Sadly it didn't. Due to the vast profits made from spare parts, repairs and repeat-use chemical additives, the truth was intentionally suppressed. And nothing has changed. Yet, as industry-standard before & after emissions results have always repeatedly demonstrated, the reaction tin-antimony alloy causes in petrol and diesel fuels eliminates carbon deposits and keeps internal combustion engines permanently clean and efficient.

“The science behind metallic surface catalysts is very well founded on the established science of surface chemistry. The combination of metals in the catalyst (FTC) is soundly based and allows these metal compositions to initiate and progress the chemical reactions involved. True catalysts take part in these reactions to form intermediary products but are found to be 100% retained at the end. This accounts for the unlimited life of the catalyst (FTC)”.

The proven effectiveness of tin-antimony alloy

FTC is a solid phase heterogeneous surface catalyst. Similar to the commercial catalysts used to initiate molecular changes during the production of bio diesel, fertiliser and plastics. Solid phase catalysts are incredibly hard and non-sacrificial which is what gives them a virtually unlimited lifespan. Tin-antimony alloy triggers a reaction in petrol & diesel fuels but is not used up in this reaction. And because FTC pellets don't dissolve, break-down or wear away you only need to add them to your vehicle once.

Tin-antimony alloy catalysts were developed by Russian scientists for use in the fuel tanks of British Hurricanes and their own fighter planes, operating out of Murmansk during the winter of 1941. Low temperature waxing issues with the local aviation fuel meant the Russian planes were restricted to operating below 15,000 ft and the British Hurricanes to under 16,000 ft. Tin-antimony pellets solved the problem and allowed the planes to operate without issues at their usual altitudes of 20,000 ft with exactly the same fuel. The WW2 campaign, code named 'Operation Benedict' is recorded in Hurricanes over Murmansk by John Golley, and in Force Benedict written by Hurricane fighter pilot Eric Carter, who served in Murmansk, and details the wartime use of fuel catalysts and their subsequent post war development.
