oil is black immediately after oil change

Thanks Waterloo. So are you saying that there is so much soot in the residual oil that it is turning 12 gallons of new oil black right away? Why is this just happening on the last two oil changes? Is there a trick to draining all the old oil that the last guys don't know? Or is my oil so much dirtier in the last two oil changes over 30,000 miles than it was for all the oil changes last year?
