Review on Synthetic motor oil Kroon Oil Poly Tech 5W-40, 5 l, 1 pc by Adam Mielczarek ᠌

Photo from VAZ 2108 1987, mileage 360 ​​thousand km. After the first application of oil, the engine began to run much quieter, only belts were heard. There is no oil consumption from replacement to replacement. I pour the same oil in Renault Kaptur 2.0l, the car is new. The engine runs softer, quieter, the work of hydraulic lifters is not audible (they were clearly audible in the old oil). Similarly, there is no oil consumption from replacement to replacement.
