When traveling to the sea, an oil burner was found about a liter per 1000 km, on the way back the indicated additive was bought and on the first day after driving about 600 km I found the level almost at the same place. the second day after driving 900 km, the oil level dropped to a minimum, I had to add a liter again. Some pros: After filling, the first 1000 km showed minimal oil consumption. With its cons: The next 1000 km has already passed in the usual oil-burning mode.
