Leak

[wahoo.ch]

For the last few months I have had an oily fluid under the driver’s door. I notice that it is progressively getting worse. I can’t see where it is coming from. It is dripping about 6 inches under the car and is just about even with the door seam on the driver’s side. Any idea what this could be? All fluid levels are ok.
Thanks in advance for suggestions.

the jack up pads that are under the car have been known to leak fluid.
Have a look underneath.
