Pardon the english...I'm American. They work and I use them. It's made of a tin and antiminey alloy. Gasoline is functionally refreshed or re-refined upon contact with the diamonds. I have modified mini Cooper. Works great. Highly recommended.
World War II invention. RAF sold planes planes to Russia. Even the best Russian fuel tucked. So they added the alloy to the Russian fuel. It fixed tge problem of poor fuel quality. Planes worked great on horrible fuel.
The best part is once the fuel is treated, it burns better (lower emmissions) and it COMPLETELY decarbonizes the engine. Try it. You'll dig it.
