      Dear All,

      According to ISO 22241 requirements AdBlue should be colourless, clear liquid. Do you test your DEF solution for clearness, ie. NTU scale?

      What is your experience?

        Hello Mark,

        We assume it is possible. We receive new pictures from our partner, on surface we have found oil spots.
