Funciona, pero hay que tener paciencia
En una Outlander 2007 empezo a marcar un codigo, no recuerdo el numero pero era relacionado a "Catalitic Converter Upper Threshold Bank 2" y estaba a punto de cambiarlo $$$ :(, pero decidí probar con este producto, al principio no cambio nada, pero a la 2da semana despues de vaciar el tanque y rellenarlo, el codigo desaparecio y ya va mas de 2 meses que no marca ningun problema, así que debes de tener paciencia para que haga efecto y limpie perfectamente tu convertidor. En mi caso la camioneta tiene 3, el que va en el escape y 1 a cada salida de las cabezas de motor en mi caso un V6 3.0L con 2 cabezas. Genial y super recomendado. Pero repito, hay que tener paciencia y no desesperar por ver el testigo de motor ahi encendido. Pense en resetearlo yo pero ha lo habia intentado anteriormente y volvia aparecer, antes de probar con este producto de DuraLube.

No fue lo que esperaba.
Le doy tres estrellas únicamente porque en mi caso no me ayudó a apagar el testigo de check enginee porbaja eficiencia de convertidor catalítico. He pensado en comprar un segundo bote y ver qué tal. Vale la pena comprarlo y ver si funciona antes de gastar mucho dinero en un catalizador nuevo.
