What was the purpose of adding lead to gasoline?
EcclesJordanTrigger
Lead was added to gasoline to inexpensively increase octane ratings and to also help reduce engine knocking.
Increasing octane and reduce engine knocking are exactly the same thing, as the test method to measure octane of a fuel is to see when a standard engine begins knocking. The higher compression ratio the standard test engine can be operated at without knocking, the higher the octane of the fuel being tested.
