It is used to increase octane number of the petrol as higher will be the octane number lower will be the detonation and knocking tendence.

TEL is an antiknokingg agent....

TEL is used as an additive in aviation fuel for piston engine-powered air craft.

It is used to reduce knocking in engine. Though it emission is harmful to environment, so now a days it is not added to petrol. Vehicle are equipped with MPFI engine with suitable sensor to reduce knocking and most of the vehicle uses knock sensor for proper combustion, which is control by Electronic Module.

It is mixed with gasoline (petrol) as an inexpensive additive and allowed octane ratings and thus engine compression to be boosted significantly.TEL was phased out in view of the toxicity of lead and its deleterious effect on catalytic converters. It is still used as an additive in aviation fuel for piston engine-powered aircraft.

Agree with avinash ji.

1 ml tetraethyle lead is added to every 4 liters of gasolene in order to increase the octane number of gasolene, as more the octane no. less is the knocking and better is the quality of gasolene.

Tetraethyl lead is added in petrol (gasoline) because it increases octane number of gasoline and it will result to reduces antiknocking activity of engine piston.

It reduces combustion of petrol and prevents knocking which catches fire easily.

The led content in the petrol reduces the volatility as it forms a layer on petrol but the led content reduces milage and gives more gasses in engine so private petrol bunks cannot maintain quality while govt bunks maintain with low led content even loss of petrol quantity.
