Quite simply, it’s soot, which diesel engines produce in much higher levels than their gas-burning counterparts. The soot enters the oil pan from the combustion chamber due to the gap in the piston rings, and it takes very little soot to turn the oil the inky black diesel mechanics are all to familiar with.
