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.

What is mean by Tetraethyl lead?
Prathibha patel said:

"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.

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.
