Don't expect miracles if your engine consumes more than 1 liter/1000km. Personally, in a 1998 Mitsubishi Lancer 1.3, it reduced oil consumption by 15-20%, in combination with 10w-40 oil. The big problem is that the engine runs quite rough and noisy, and exhaust smoke also increased. Don't use it in winter!!!

Worn engine Subaru Justy 1000cc year 2011 and 140,000 km, with oil consumption of 2 liters / 1000 km! (Manufacturer's specifications are 1 liter / 1000 km). After adding this specific additive during the oil change, consumption was reduced, below the manufacturer's specification!! (600-700 g per 1000 km)! Noise was also reduced as it seems to have made the engine run better! Of course, it doesn't work miracles, it just gets the job done until you decide what to do with the engine!

I used it because my car was burning oil. After 1000 kilometers of use, the oil loss is minimal. I definitely recommend it without reservation to those who have the same problem.
