I've noticed mostly my left side being that way, but that's the side operating at lower rpm's and gets the "cold start" cycle. After long highway trips, they generally even out but still show some soot. Oil level stays the same for 6000 miles so I'm not too worried. I stick with Shell gasoline all the time.
