In my answer to the question I was not saying you should use low sulphur diesel, I was merely saying it will not hurt the engine. As richV70 said, it will not cause the dpf to fail, it will merely shorten it's life. Which none of us no what that life is, I am very confident it is less than what Ford says. Being a pessimest here but anything that goes through the temperature swings this thing does is going to have problems.
