Tetraethyl Lead

Tetraethyl lead (TEL) is an important additive for aviation gasoline, mainly used to improve the anti-knock property (octane number) of aviation gasoline, and also plays a role in preventing shock and explosion. In the Middle East market, the aviation field of many countries, especially aviation gasoline (AVGAS 100LL) involving old piston engines, still relies on tetraethyl lead as a key additive.
