Synthetic oils can also be used in a diesel motor. 5W-40 synthetic can be used in most newer motors with equivalent or better results than a regular 15W-40 oil. Synthetic oils are more expensive, but provide additional protection against motor wear and tear.

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.

Why is my Diesel Oil Black? So when your mechanic changes the oil in your car, the golden amber liquid is quickly darkened by the residual oil and carbon build-up in the engine. That change in colour is a sign that the oil is actually doing its job.

After changing Diesel oil in an engine it will always look blackish and never a golden colour after only a very! short period of time. This is because the old oil residue left when the oil is changed will always retain a certain amount of contamination and cause the discolouration.
