Black engine oil after an oil change can mean a severly worn lower half of an engine possible main bearings.
If you are talking about the spot being black on concrete or the oil on the bottom of the engine?
Oil loves dirt also depending on the type of filter you are using will determine the color or how clean your oil is. I recommend using WIX they are not cheap but they do work. After a couple of oil changes you will notice your oil will not appear so black. The black is deposits in the oil.I also recommend using a good brand name oil that won't break down and changing every 3000mi.
Well this should still have answered your question but if not I will go into more detail. When your engine is running it will build up deposits in the oil (carbon and broken down oil molecules, acids) if the filter is not removing these it will appear black. Or if you are using a cheap oil it will break down sooner, or if the oil isn't changed regularly it will be black
Is it a body rattle or an engine rattle
I see that you gave me an innappropriate rating that was unnecessary. This is a free service to you and costs me my time. I hope someone else can help you I won't

Don't forget to change the filter with each oil change. When you change the oil, the soot from combustion sticks to the inside of the motor and does not all come out with the oil. Also there is always a little old oil here and there in the motor that does not drain out, and that will give it's color to the new oil. You can have your motor rinsed, but it is more important to change the filter regularly. Stay with one brand of oil, don't switch around. You can change the viscosity (30w/40w) from summer to winter. It's not a great idea to have thick oil in a motor if it gets below freezing outside. A rattle can be a heat shield coming loose, you'll have to have help to find it.

I have the very same problem with my 2003 Nissan Altima. It drank almost 10 quarts of oil in less than 3000 miles. Top it off the oil is pitch black when it is full.
