Black carbon on exhaust outlets?
I have only put about 500 miles (mostly highway) on the SRT6 in the last three weeks. I bought it in January and stored it until then. I had the dealer from whom I purchased it change the oil to Mobil1 0W-40 since they had originally put in regular 10W-30 oil.
Otherwise, as far as I know, it is original spark plugs and air filter.
I notice a small amount of black carbon, almost like soot, on the exhaust outlets. It cleans right up, but I don't recall seeing this build up as fast on my roadster. Is this normal for an SRT6 or do you think I have a potential problem (worried about burning oil)? I did check the oil and it was down about 1/2 quart so I topped it off. I did not think to check it when I got the car and it could just be the boneheads who last changed the oil did not realize it takes more than 8 qts. I'll be checking the oil frequently for a while. There is no spotting under the car.
