Black soot on exhaust tips

So what does it mean when the pipe is perfectly clean? From day 1, our '14 always had the black soot around the pipe, a normal thing to wash every week. But the last few months I notice it is no longer there.
I would rather not have the soot, but it's sort of weird that it quit appearing, obviously it's running different, good or bad (uhm)

you have a secret admirer that washes your tips unbeknownst to you?

:p
 
The exhaust tips of my 4 month old 2016 CX-5 is blackened with soot and looks like this. My finger gets black when I wipe it.

Don't have this problem in my 2005 Lancer. This car is 10 years old, 125k miles and the tips look clean (except for some rust) like this. No black soot. My fingers don't get black when I wipe it.

I had a 2008 Accord until 4 months back and didn't have this issue in that car also.

Is this typical for CX-5? If not, what's going on and what can I do fix it? Is this because the engine might be burning oil?

Have you ever smelled a carbed vehicle without emissions crank up? That is how my CX5 smells. It's burning a TON of raw fuel on cold crank.

Let me help you understand what might be happening.
