This podcast explains what oil is for. Some Yolngu people think that motors can run without it. This is an especially big problem where many communities rely on boat transport along the northern coast. Unfortunately, many outboard motors don’t last very long! It’s important to remember that Yolngu are living in a time where a lot of post-industrial information is very new to them, even if it seems very common to Balanda. This program explains how oil reduces friction between the different parts of the engine or the vehicle and the practical examples to explain what oil is for.
