[LeStella]

Tighten or replace the drain plug. Aged or defective sealing gasket: If the sealing gasket is aged or of poor quality, it is necessary to remove the oil pan and replace the oil pan sealing gasket or apply sealant to the local leakage point. Overfilling or overly thin oil: If the replaced engine oil does not meet the original vehicle's standard specifications, the oil viscosity is too thin, or too much oil is added during the oil change, it is important to ensure the oil level remains within the normal range.
