Where exactly is the oil pan located?

... on the bottom of the engine, where it is on every car in the world. You may be missing it because there's a plastic part covering the drain plug/filter. But, since I don't know which car you drive or what the exact nature of your question is, I can't really help more than that.

Did I read the question right?

Yes, yes you did.
