Today I had the bright idea of running my finger in the muffler end of my 2010 cascadia DD15, I got a bunch of black soot on my finger. Now I'm freaking out, I thought the exhaust should be clean. How dirty can it b?. I decided to check exaust because I had to add about 3.5 quarts of oil which is was a bit more than normal. It usually maby takes that in 7000 miles not 3000, i do have a small leak at the fuel pump. What should I be looking for.
DD15 Dirty exhaust.
