Hello, it’s about the Hyundai of my sister. The car ran about 120,000km. It’s the 1.6 GDI, unfortunately the oil consumption is too high in my opinion. On about 900-1000 kilometers the oil level drops from maximum to minimum. Noteworthy for extreme short distance (3x daily approx. 3 kilometers) I was with the car a week ago in Croatia, before I did an oil change with the filter with the Motul 5w40 Xcess to see if something changes. (The contract factory sta.) dt always fills 5w-30). Result: after 2600 kilometers the oil level is close to minimum. The cooling water is clean, there is no blue smoke from the exhaust. I have read that the problem with the engine is known, is that true? Is there a defect or is it so ok? Thank you in advance.
