    MODERN engines will not suffer ill-effects from the   unleaded
gasoline.  However, OLDER engines (made before the introduction of
unleaded gasoline) do not have hardened valves and stem seats.  They
require the lubrication provided by leaded gasoline.
    Unleaded gasoline is more expensive to produce for the same octane.
Additionally, it requires more crude to produce the same octane as
unleaded.
