I started using Lubrifilm metal at about 90 thousand km. I felt the effect of its use after the first thousand kilometers, the engine began to run quieter and smoother, it felt like it had more traction, especially when climbing. If before using Lubrifilm, the oil was being eaten up, about a liter per 10 thousand km, then since I started using this additive, the oil consumption has stopped. I use the additive every time I change the oil. As a result, I can say that it is cheaper to use an additive that really works than to do a major overhaul. The engine and attachments are all original, including the turbine, fuel injection pump, and chains. I am not going to change the car, I will continue to check the Wear-Free Technology.
P.S. Fuel consumption has decreased, and instead of the standard 13-14 liters per hundred, I now have 8-8.5 liters. And this is good.
