The first car in which I used ceramizer was Żuk with a Polish diesel engine (2.4 Andoria), I was the first owner of this car and I used it for 11 years. After driving 120 thousand. km there was a timing change and I changed the oil from elf to lotus. After driving 1,500 km, the oil condition decreased to a level below the minimum (before the change, 2 liters of oil were enough for about 15,000 km, and after changing to lotus oil, a liter of oil for 1,500 km). A mechanic friend told me to buy a ceramizer for the engine and gearbox and so I did. After the use of ceramizers, oil consumption returned to normal (2liters per 15,000 km for replenishment as from the novelty), and the gearbox was used without repair, up to a mileage of 190 thousand. km and the car was sold in good condition.
