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

In 1942, the American motor industry discovered the tin-antimony pellets, used in the fuel tanks of Hurricane and Yak* fighter aircraft, caused petrol and diesel fuels to self-clean as they combusted. Removing carbon deposits and keeping engines permanently clean. They were worried. This would put a huge dent in the profits from spares, repairs and annual engine de-cokes. And could even slow new car sales. But for the fuel additive companies, with dispenser cans on every fuel pump stand, the news was a complete disaster! So they started a smear campaign. And motoring's biggest lie was born.

Along with the snake oil slurs and stories of exploding engines, the plausible sounding 'if they were that good the manufacturers would fit them' was circulated through main dealers and garage networks. It didn't take long before motorists were repeating the propaganda circulated to fool them! Over the last 80-years, motoring's biggest lie has been used so many times, especially in the UK, many have come to believe it. With misleading press, straw man tests and red herring reviews, repeatedly used to protect the profits from needlessly dirty engines.

In widespread commercial use for the last 60-years

Tin-antimony alloy was first used commercially in South Africa during the 1960s, in Anglo American Mining's underground vehicles and heavy machinery to keep emissions permanently low. It was then used in SAF Marine's container ships to cut black smoke, prevent fuel wastage and extend service intervals. Over the next 30-years, as independent tests repeatedly confirmed the alloy's unique ability to eliminate carbon deposits, its use steadily increased. 

Following the results of the Philadelphia Coca Cola Company's fleet trials in 1998, the US military conducted 14-months testing at Camp Pendleton and the Naval Facilities Engineering Service Center. In 2003, the Senate Committee on Armed Services announced the results to Congress with the recommendation that Donald Rumsfeld, Secretary of Defense, take immediate steps for the application of fuel catalyst technology.** Since then the use of tin-antimony alloy has exploded worldwide. And today fuel catalysts are used by private and commercial vehicle owners in every imaginable make, model, type and age of petrol and diesel vehicle. 

Why fuel catalysts work so well in modern vehicles

The reason we don't notice carbon deposits gradually building up in modern vehicles, is because the ECU hides the symptoms by retarding the ignition timing to prevent overheating, pinking and knock. This has a negative impact on combustion efficiency and engine performance. And increases fuel consumption and exhaust emissions, leading to the fuel-heavy soot deposits that clog EGR valves and block DPF filters. Removing carbon deposits reduces the engines operating temperature, allows the fuel to combust efficiently which enables the ECU to progressively reset/re-advance the optimum ignition timing settings.

The motor industry's Worldwide Fuel Charter clearly states, even the use of high-quality fuel leads to deposit formation, affecting vehicle performance and increasing engine-out emissions. The Society of Automotive Engineers and the Handbook of Air Pollution from Internal Combustion Engines confirm, carbon deposits affect all engines, causing reduced power, reduced fuel economy and increased emissions. Which is why carbon deposits are the root cause of the excess traffic pollution that ruins the air quality for hundreds of millions of people in towns and cities worldwide.

The proven effectiveness of tin-antimony alloy

The significant improvements reported by FTC customers, are only ever the result of carbon deposit removal. Fuel catalysts cannot produce before & after results in a new or clean engine (where there is no carbon to remove). In a brand-new vehicle, or one with a clean engine, tin-antimony alloy simply stops deposits from forming in the first place. Which simply means engine performance, fuel economy and exhaust emissions all remain virtually the same as those of a brand-new vehicle.

For the last 60-years, the effectiveness of tin-antimony alloy, has been measured and observed using industry-standard before & after emissions results - the same way liquid fuel additives are tested. But whilst a single proprietary clean-up test in a static lab-based engine, has always been sufficient for the fuel additive companies to claim a chemical can remove carbon to restore performance, economy and emissions, some suggest the same standard doesn't apply to an alloy! Especially one that offers motorists a permanent alternative to expensive super-fuels and repeat-use chemical cleaners!

In addition to independent before & after testing and Department for Transport approved MOT emissions results, FTC has been independently tested by world-leaders Emissions Analytics Ltd, using the latest real-world emission measurement system - PEMS. 

The origin of tin-antimony pellets

Tin-antimony alloy was originally developed by Russian scientists in 1941, for use in the fuel tanks of Hurricane and Yak fighter planes during WW2. Low temperature waxing in the local aviation fuel, was causing crystalline deposits to clog carburettors leading to engines cutting out and mid-air stalling. The planes were restricted to 16,000 ft until a solution could be found. When tin-antimony pellets were added to the fuel tanks, the planes were able to operate over and above their usual ceiling of 20,000 ft with exactly the same fuel.
