Lead was commonly used in auto gasoline as tetraethyl lead to improve octane ratings and reduce engine knocking. In the United States, lead levels in gasoline peaked in the 1970s at about 0.5 grams per liter (or 0.5 grams per gallon). However, due to environmental and health concerns, lead was phased out of gasoline, with the complete ban occurring in the U.S. in 1996. Most countries have since followed suit, significantly reducing lead exposure from automotive sources.

Lead was added to gasoline in the 1970s as an anti-knock agent to improve engine performance. However, it was later discovered that lead in gasoline was harmful to both human health and the environment, leading to its phase-out in the following decades.
Why do people use unleaded gasoline?

During what time period was lead-free gasoline first introduced?
Actually, the first gasoline was unleaded. Sometime in the 1940s lead was added to increase the octane rating. Environmental legislation in 1975 began the phase-out of leaded gasoline.
