Cataclean6160 Diesel DPF & Catalytic Converter Cleaner, Diesel, 500ml

One thing you have to understand. A bad catalytic converter code does not necessarily mean a bad catalytic converter, but if your converter is truly bad, this will not fix it. It will fix dirty O2 sensers or excessive carbon build up inside the converter... If that honeycomb metal Is melted inside... Should I say more?

Thought for 35 bucks I was getting the 6 pack case that’s in the photos. Take the photo of the case off of the picture of product. If I would of known it was one bottle I would of never spent that much on it.
