"Tetraethyl lead" was used in early model cars to help reduce engine knocking, boost octane ratings, and help with wear and tear on valve seats within the motor. Due to concerns over air pollution and health risks, this type of gas was slowly phased out starting in the late 1970's and banned altogether in all on-road vehicles in the U.S in 1995.

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.

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.

Octane number is used to calculate the quality of fuel. Octane no. is used for petrol. It is calculated by checking the total no.of parts of ISO octane in a mixture of ISO octane and n-heptane. Greater the octane number the greater is the calorific value and lesser the emissions.

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.

TEL was mixed with gasoline (petrol) beginning in the 1920's as a patented octane rating booster that allowed engine compression to be raised substantially, which in turn increased vehicle performance or a fuel economy.

TEL B is used to making Aviation Gasoline aka Aviation Petrol highly dangerous Chemical it's a antiknocking agent and increase the octane number of Petrol it's iffect damaged the human IQ system.

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