Etymology

The term 'unleaded' originated as a part of the movement to improve air quality in the late 20th century. In the 1970s and 1980s, various countries began to phase out leaded gasoline due to its detrimental effects on human health and the environment. The lead found in fuel was a byproduct of using tetraethyl lead as an octane booster, which was common practice in the early automotive industry. As the awareness of environmental issues increased, alternative fuels that did not release lead into the atmosphere became necessary. Consequently, the automotive and petrochemical industries developed unleaded gasoline to meet new regulations and public demand for cleaner fuel options, leading to a significant shift in fuel production and consumption.
