Why does the BMW Mini N16 engine burn oil?

[McGabriella]

There are reasons why the BMW Mini N16 engine burns oil. Environmental factors: Due to different driving conditions, domestic fuel quality and road conditions can easily lead to carbon deposits, causing the piston rings to stick and lose their oil-scraping performance. Engine factors: Blocked oil return holes prevent oil from returning normally to the crankcase; wear between the cylinder walls and pistons leads to excessive gaps; corrosion and aging of valve seals and crankshaft seals cause oil leakage. If sealing components fail, the working surfaces cannot be lubricated, resulting in severe wear. This can also damage other functional components, rendering them inoperable, or cause oil leakage due to corrosion and aging of valve seals and crankshaft seals. Solutions: Take the car to a 4S shop for engine repair, including replacing the piston rings and valve seals. Regularly inspect the engine for internal issues. If the engine emits blue smoke during high-load operations like idling starts, it should be sent for maintenance. Additionally, using high-quality engine oil ensures good operational efficiency and reduces such occurrences.
