To the third power actually.

Someone didn't take thermodynamics.

I've been tracking the data myself with torque. Fuel consumption per unit time increases with the square of speed because after 65mph drag does.

Someone has got his units mixed. Fuel volume is (can be converted to) energy, fuel per unit time is power. Drag is force. Force times distance is energy, Force times speed is power. Drag, a force, goes with the square of speed, as the drag related term of fuel consumpion per distance does. Power goes with the drag ( square speed ) times speed, as the drag related term of fuel consumption per time does.
