Re: Use of avgas?
Hallo und guten Abend!
Tetraethyl lead is often only considered as a knocking brake for highly compressed engines.
Leaded fuel also has the great advantage that good emergency lubrication is guaranteed in the very high temperature-related limit lubrication area (piston/cylinder at top dead center, exhaust valve stem, valve seats).
To date, the replacement has not been fully successful!
