Clean off the engine and put some UV dye into the oil.

That is a fair leak and you should have it repaired, not just for your vehicle's sake, but because you are dumping all that oil onto the ground and letting it seep into the surrounding environment.

If you can't identify where the leak is by eye, get a bottle of UV-reactive tracer dye (like this or equivalent: https://www.amazon.com/dp/B000JFHNTM/ ) and add it to your oil. After letting it circulate, you should be able to use a UV flashlight at nighttime to identify where the oil is leaking out.

My buddy at work today mentioned using some of [this stuff] (https://www.amazon.com/Tracer-Products-TP34000601-Fluorescent-Detection/dp/B000JFHNTM). They make other brands and cheaper versions etc. It's UV dye that will show up under a black light, it's made for finding these kinds of leaks. He said that it will work much better than soapy water (the soapy water might not work with the fuel system) Pour the dye in the gas tank run the car for a bit and use a blacklight to check out the lines the tank etc.
