Tin-antimony alloy keeps engines permanently clean - that's why the motor manufacturers don't use it

In 1942, the American motor industry discovered the tin-antimony pellets - used in the fuel tanks of British and Russian fighter aircraft* during WW2 - caused petrol and diesel fuels to self-clean as they combusted. Eliminating carbon deposits and keeping any engine running like new. They knew this could put a huge dent in the profits from spares, repairs and could even slow new car sales. But for the fuel additive companies, with dispenser cans at every fuel pump, the little pellets spelt complete disaster. So they started a smear campaign. And motoring's biggest lie was born.

Along with snake oil slurs and stories of exploding engines, the plausible sounding, 'if they were that good the manufacturers would fit them' was circulated through the motor trade. It wasn't long before motorists were repeating the propaganda circulated to fool them. Over the last 80-years, motoring's biggest lie has been repeated so many times, especially in the UK, many have come to believe it. With misleading press, straw man tests and deceptive reviews, repeatedly used to suppress the truth.

In widespread commercial use for the last 60-years

Tin-antimony alloy was first used commercially in South Africa during the 1960s, to keep emissions permanently low in Anglo American Mining's underground vehicles and machinery. And 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 its unique ability, the alloys 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.** As a result, tin-antimony fuel catalysts are now used worldwide by the owners of every imaginable make, model, type and age of petrol and diesel vehicle.

Carbon deposits happen in all engines

The motor industry's Worldwide Fuel Charter clearly states, even the use of high-quality fuel leads to deposit formation, causing reduced power, poor fuel economy and increased engine-out emissions. Which is the 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 reason we don't notice deposits building up, until our dashboard warning lights start flashing, is because the ECU hides the problems by retarding the ignition timing to prevent overheating, pinking and knock. But retarding the timing reduces engine performance, reduces fuel economy and increases exhaust emissions, resulting in the fuel-heavy sooty deposits that clog EGR valves and block DPF filters. Removing carbon deposits reduces the engine's operating temperature, restores combustion efficiency and allows the ECU to progressively reset the ignition timing.

The proven effectiveness of tin-antimony alloy  

For the last 60-years, the effectiveness of fuel catalysts has been easily demonstrated using before & after emissions results - the same way liquid fuel additives are tested. But whilst a single, proprietary test in a static engine has always been sufficient for the fuel additive companies, special interests insist the same standard doesn't apply to an alloy! Especially one that makes liquid additives obsolete!! However, in addition to Department for Transport approved emissions results, FTC has also been independently tested by world-leaders Emissions Analytics Ltd. 

The significant improvements reported by FTC customers, are only ever the result of carbon deposit removal. Tin-antimony alloy, can't produce results in a new or clean engine, because there's no carbon to remove. In a new vehicle (or one with a clean engine) catalysts stop deposits from forming. Which simply means performance, economy and emissions, all remain virtually the same as a brand-new engine. 

The origin of tin-antimony pellets

Tin-antimony pellets were originally developed by Russian scientists in 1941, for use in the fuel tanks of Hurricane and Yak fighter planes operating out of Murmansk on the Russian front 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.
