If you are facing this problem, then take your car to a mechanic to check the issue, whether it is a leaking seal or damaged oil gasket.  

Broken Oil Filter

A damaged oil filter can be one of the reasons for oil leakage. If the oil pan is damaged, then it can leave a puddle of oil under the car.

When you are driving a car, your vehicle goes through lower-lying road portions or through such roads that have potholes. It can put a dent in the oil pan and cause damage if it is hit with a large force. The end result of this trauma can cause a leakage that can get worse with time.
