I have a 2009 range rover full size supercharged and I have noticed after driving and parking there is oil that drips from very front passenger side. I can small amount of oil dripping from the passenger side front plastic cover underneath the car. It only drips after driving and it is parked. I have confirmed that it is in fact oil. It is not coolant, windshield fluid, or any other kind of fluid. Any ideas on what could be leaking? The car has 160k miles on it.
