I have an '06 hatch 2.3L with 15K miles. I got it 6 months ago with about 200 miles on it. Since i've gotten it i noticed a black deposit coming out of my exhaust and staining the bottom of my exhaust tip. I took it to a dealer, and they said it was "normal"(right, ok, sure). Now i have a two-tone exhaust tip (flat black/chrome) and it won't wash off. Then the oher day i checked my oil to make sure it was ok since i haven't been able to change my oil in the last 8,000 miles. The oil barly even registered on the dipstick!! This is my first new car, as i've had plenty of used ones before. These issues are something i'de expect from a used car wither over 100K miles on it. I think i could have a bad piston ring, and could be burning oil. I need proffessional advice on this matter on what i should do. Am I just over reacting, is this really "normal" or is there something terribly wrong here???
