I don't believe there is a such thing as a leaded fuel engine. All gasoline is unleaded, some just a higher grade.

Why would you do this? This is difficult to do by accident as the filler nozzle, through which unleaded fuel is delivered, and the filler pipe on the car are both narrow. The wider nozzle used with leaded fuel and diesel just will not fit. Leaded fuel will quickly destroy the catalytic converter and O2 sensors. What other damage will be done is hard to say. Use unleaded and forget leaded fuel.
