So after reading multiple threads about soot in oil, curiosity got the better of me and I went out and wiped the dipstick on a clean, white, lint free cloth. The results made me ill. Black as coal with 80% life left. Nuts to that, says I. So I cashed in one of my free oil changes at the stealer and also got the tires rotated. Got a feeling I'm going to be doing this a lot, but I can't stand the look of that nasty oil.
