Hey dear
Here is ur answer

An antiknock agent is a chemical that, when added to gasoline, raises the octane value of the gasoline which, in turn, raises the temperature and pressure at which gasoline will auto-ignite. It allows the gasoline/air mixture to wait until the spark plug ignites the fuel, reducing pre-detonation which can be harmful to the engine.
The first widely used antiknock agent was lead. It worked quite well and had the side effect of being a good lubricant for valves and valve seats.
Hope it helps u
Have a great day
