The question of which motor oil is suitable for diesel motors keeps coming up, again and again. But the times in which there were special motor oils for diesel motors are long gone. Modern motor oils fulfill both the requirements of petrol and diesel motors. What's important in the selection of the right motor oil is much more the specification or approval given by the vehicle manufacturer. If this is printed on the bottle label, then the oil can be used for the respective motor. Regardless of whether it's diesel or petrol.
