There is currently no study being done in this area that uses tetra ethyl lead to increase the octane rating of gasoline.
Most spark-ignited internal combustion engines use gasoline or petrol, a clear, petroleum-derived combustible liquid, as their primary fuel (also known as petrol engines). The majority of its constituents are organic molecules derived from petroleum through fractional distillation, augmented by a number of additions. An typical barrel of crude oil yields 19 to 20 gallons of gasoline, 11 to 13 gallons of distillate fuel, the majority of which is sold as diesel fuel, and 3 to 4 gallons of jet fuel at U.S. refineries. An oil refinery's operations and the crude oil test determine the product ratio.
