Bad product
I add to improve my car petrol efficiency, but it damaged the Oxygen sensor, and now I have to replace it, usually I use another brand, I changed to Wynn, maybe it can improve more as it is more expensive, but the result was very bad

O produto chegou antes do prazo mínimo estabelecido.👍 É importante salientar que apesar de prometer limpeza de catalisador e sonda lambda, existem casos que não há milagre e somente a troca da peça defeituosa vai resolver seu problema. Mas por R$90 contra R$1200 em um novo catalisador, posso afirmar que após 100km rodados com o produto no tanque do veículo, obtive uma melhora de performance substancial. Veículo: Ford Fiesta 1.6 Rocam 2012 Falha: Baixa performance de catalisador / Luz espia acesa no painel / Fraqueza nas acelerações e alto consumo (5.5Km/L) Wynns foi aplicado em 3/4 de tanque e usado veículo em perímetro misto urbano/estrada , sempre deixando as rotações médias acima de 2500rpm. Retomada força nas acelerações retornaram após os primeiro 25km percorridos, a luz espia apagou e o consumo está na média de 8.5Km/L.

After using this in the gas exactly as the directions say, a clear difference could eventually be felt in the power of the engine. I bought a second one and repeated the treatment for best results. I can't see in the converter but overall this product worked.
