What Causes Engine Oil Burning in New Cars?
2 Answers
New cars burning engine oil is mainly caused by unsynchronized fuel standards or engine carbon buildup. Details are as follows: Unsynchronized fuel standards: Due to the discrepancy between domestic fuel quality and international standards, a large amount of carbon deposits easily forms in the combustion chamber during engine operation. Carbon buildup is the root cause of various engine problems. Engine carbon buildup: Carbon deposits accumulate in the piston grooves, causing the piston rings to stick together. This prevents the piston rings from sealing properly, significantly reducing their oil-sealing capability. Additionally, sludge can clog the oil return holes, preventing normal oil circulation and leading to increased oil consumption.
There are quite a few reasons why a new car might burn engine oil, possibly related to engine design or manufacturing. For instance, if the piston rings don't seal properly, oil can seep into the combustion chamber from the cylinder walls and burn; damaged valve stem seals are also a common cause, especially in new cars where they might not have been installed correctly from the factory. In the case of turbochargers, leaking oil seals can lead to oil being sucked into the intake system. During the break-in period of a new car, frequent high-speed or heavy-load driving can increase pressure, making these issues more likely to surface. I think it's crucial to check the engine oil consumption promptly by using the dipstick regularly. If the oil level drops quickly, don't delay—take it back to the 4S shop for warranty service to avoid further engine damage and costly repairs. Driving gently and choosing a reputable oil brand can also help prevent some of these issues.
