Works as advertised
Very good product. It reduced the smoke from my Mini Cooper S due to worn valve seals. Before, you could see smoke on idle and a good size puff upon taking off. Now after 500 miles of driving with the product in the car, I can only see a very thin haze of smoke after extensive time idling. Very inexpensive fix compared to replacing valve seals.
