      Wynn's Catalytic Converter works fine. If the MM warning light comes on occasionally, check the OBD: CC system; efficiency below threshold. Then mix the gasoline with Wynn's, and the message should disappear for a while!

      Added the bottle to 30 liters of petrol and since then no more engine failure light. The Wynss's has done its job well.
