What Does TEL Stand For?
TEL stands for Tetraethyl Lead
TEL, or Tetraethyl Lead, is an organic compound historically used as an anti-knock agent in gasoline to enhance engine performance by preventing premature fuel ignition. Although it improved fuel efficiency and engine longevity, TEL has been phased out in many countries due to its toxic effects on health and the environment, leading to significant regulations and alternatives being developed for use in automotive fuels.
