Just bought an 06 6.0. With 59k on the motor... When I'm driving around I notice a haze of black smoke between shifts ( it's a manual ). Also, today when I left it idled while I was in a meeting at my office, and when I left about an hour later it was smoking white/slightly blue for about 5 miles then cleaned up... Is this normal? Or is something wrong? It's still under warranty... It's my first 6.0 so o don't know much about them.
