Uses Tetraethyllead is used as an additive to gasolineto prevent knocking in motors. However,because of its high toxicity and the pollutionproblem, its use in gasoline has been drasticallycurtailed. As a gasoline additive to prevent "knocking" in motors.Its use, however, is reduced drastically because of environmental pollution.
