Europe ban on Tetraethyllead In Europe, the situation is more perilous with Tetraethyllead (TEL), the additive which adds lead to avgas, being added to a list of
banned substances by the European Union. TEL will not be allowed to be imported into the EU which would end European production of 100LL avgas.
TEL is currently on an Authorisation List that allows it to be used until 2025. It’s not known whether Innospec, the UK based company which is the world’s sole supplier of
AvTel, will apply for an extension of that date – or whether the EU would grant it. Nor do we know (despite asking) if there is any plan by fuel companies to import 100LL avgas from outside the EU.
