The oil price is up to 1 litre per 1,000 km. Thus, in most cases, the owners ' concerns about the "greyness" of their cars are unfounded. At the same time, possible causes of high oil consumption should be checked and eliminated.
The first of these is the incorrect operation and driving style (e.g., filling of poor or inappropriate oil, driving at high speeds with frequent accelerations/braking). Also, possible causes of the increased flow can be flows through compaction (pay attention to the gasket of the HC and the saplings), the valve of the crankcase ventilation or the wear of the parts of the cylinderpistle group.
