Engine oil’s job is to keep the engine running smoothly by lubricating moving parts, helping to clean by suspending and carrying away contaminants, and aiding in cooling by absorbing heat from hot components. Conducting electricity is not a function of engine oil; it’s an electrical insulator, so it does not serve to carry current. The first three functions—lubrication, cleaning, and cooling—are established roles of automotive oil, while electric conduction is not part of its purpose.
