"Moreover, there's the matter of lubricants. Lubricating oils and greases are widely used for lubricating various machines. Without lubrication, almost all machinery can't function properly.
The majority of lubes and greases (butter) consist of base oils refined from petroleum. Many lubricating oils contain 90% petroleum.
The common lubricating oils are engine oils for car engines, commonly known as motor oil."

He's not omniscient; he can't understand every industry and field.
