Lead was original used to help prevent knocking in vehicles. Its current application in fuel is very rare one of the last registered places using leaded fuels is Indonesia. Knocking occurs when the engine fails to combust correctly. It is the goal of a manufacturer to have complete combustion each time air/fuel mixture enters the chamber, however if the octane in the fuel is too low, often the mixture will ignite prematurely (before the spark), this is a common mishap with petrol engines of many types and is also known as 'pinging'. It may only become noticeable when the vehicle is under larger amounts of pressure such as driving up hills, if it begins to overheat or when a poorer air/fuel mixture has come about by means of too low octane fuel type or suffocation (air filter element needs replacement).
