The last cars that were made to be run on leaded gasoline were the 1978 Hondas with the CVCC engine. All other cars went to unleaded only for 1975. GM had unleaded capable cars in 1971, but they could still use leaded. I guess that they needed 20 years for most of those pre-1975 cars to be taken off the road.
