Producto preventivo, usar con pulverizador directo al ducto de admisión! No se usa vertiendo en el tanque de combustible.

I used this on our L650S Mira Gino because the fuel mileage was bad. I bought a cheap sprayer to spray the liquid into the throttle body while the car ran. It created a lot of smoke. Following the treatment, I replaced the oxygen sensor after the catalytic converter. The car seems to have more power and is getting better fuel mileage!

This cleared an emission fault for a fiat 500. Generates a ton of smoke, but it works.
