Due to the high "cheap" oil consumption (3l / 1000km) I got involved for a try with this "Premium oil". Use this oil found in my Skoda Fabia 1.4 MPI engine BJ 2001. The first canister was after 2000km empty. After a subsequent oil changes and even repeated filling with this oil consumption decreased measurably.
Today, about 6000km later I go with 1l / 1000km and am fully satisfied.
Conclusion: I do not know if this oil helps in every car to reduce oil consumption. But I'm sure it has helped me, because no close-coupled hardware has been replaced or repaired.
