Looks just like mine does most of the time! I only do about 6 miles a day and after a week its like that. I have a catch can and that fills up pretty quick too. I used to be worried about it but I've changed the oil twice (in 1 year, 4k miles) had a few big journeys and it always goes back to normal pure black after a good run. Then when I use it just for getting to work and I get the mayo back.
