why is there black wet soot in the exhaust pipe? Could it be excess oil?

What is your question?

The vehicle is 2 years old and has barely been used - under 5000 km. (A courtesy check / top up of the engine was done at the dealership last year). It is parked most of the time. I have been using it for 2-3 weeks. When you touch the inside of the exhaust pipe, you get wet black soot / oil residue on your finger? Is it something serious or would a good long drive at high revs clear it and get the engine running OK.
