My recollection is that one requirement for unleaded fuel was driven by the
catalytic converter.  The lead in the fuel would make short work of the
catalyst by it becoming coated with lead from the fuel and destroying its
ability to function.  Another, of course, was to eliminate lead in vapors
emitted into the atmosphere.
