Two vehicle tests to determine effect of leaded and unleaded gasoline on exhaust emissions were carried out; first test involved 122 cars without exhaust control systems and other 36 cars with systems; hydrocarbon exhaust emissions of leaded and unleaded cars increased during initial period of mileage accumulation and leveled out as equilibrium was reached; average hydrocarbon emission levels of leaded cars were higher than those of unleaded with difference or net lead effect amounting to 7% in both tests; no significant differences in carbon monoxide or nitrogen oxide emission levels were observed; photochemical reactivity levels were essentially same; results of study of effect of mileage accumulation conditions.
