tetraetylbly
Also known as tetraethyl lead, lead tetraethyl, TEL, tetraethylplumbane, [PbEt4], PbEt4
Tetraethyllead (commonly styled tetraethyl lead), abbreviated TEL, is an organolead compound with the formula Pb(C2H5)4. It was widely used as a fuel additive for much of the 20th century, first being mixed with gasoline beginning in the 1920s. This "leaded gasoline" had an increased octane rating that allowed engine compression to be raised substantially and in turn increased vehicle performance and fuel economy. TEL was first synthesized by German chemist Carl Jacob Löwig in 1853. American chemical engineer Thomas Midgley Jr., who was working for the U.S. corporation General Motors, was the

Tetraetylbly, TEL, var tidigare en vanlig tillsats till bensin för att minska risken för självantändning (på grund av kompressionstryck). På grund av blyets miljöeffekter har användningen av denna tillsats i stort sett upphört men den används fortfarande i flygbränsle.
