[OEliza]

Consequences of oil leakage in a 2011 Buick Excelle engine: It will affect the engine's working efficiency, leading to reduced vehicle power; it may produce abnormal noises, and the engine may experience unstable idling or poor acceleration during operation; overtaking performance may also be diminished. Specific details are as follows: Oil pan damage: Since most vehicles have relatively low ground clearance, if the driver operates the vehicle on rough or poor road conditions, the oil pan may be damaged due to scraping or impacts from flying stones. As the container for storing engine oil, any damage to the oil pan will immediately result in oil leakage (most oil pans are made of aluminum alloy, though some are constructed from stamped steel plates). Drain plug loosening or stripping: If during vehicle maintenance or oil changes, the drain plug becomes loose or stripped due to worker negligence or improper operation, the engine will inevitably leak oil.
