In the US, 13% of the gasoline sold for use in automobiles in 1988 was leaded; the rest was unleaded. Cars manufactered after 1975 were designed to use only unleaded gasoline, and these get higher mileage per gallon of gasoline on average than do pre-1975 automobiles. In 1988, 18% of autmobiles used only leaded gasoline.
