Teta-ethyl Lead.... But they rarely use that anymore because of its toxicity. Additives found in most of the gas are now hydrocarbons ethers and alcohol.
Lead and oxygen are the elements in lead dioxide.
Lead is an element and is natural, but is not often found in its pure state. It is usually found in an ore that has a lead compound and a mixture of other compounds of other metals. It is then refined to produce more pure lead metal.
Lead - in the form of Tetraethyl Lead
This compound is lead (II) acetate with the chemical formula Pb(CH3COO)2.
The name of compound Pbl2 is lead(II) iodide.
gasoline that has not been treated with a lead compound
In addition to the hydrocarbons present in normal gasoline, leaded gasoline contains tetra-ethyl lead or other lead alkyls for their anti-knock effect.
Unleaded gasoline is regular gasoline. Lead used to be added to gasoline to prevent engine knocking but the practice has been banned in most developed countries. 2nd Answer: There are some engines, a lot of them not in cars, that are made to use regular gasoline. They are designed so that the lead in regular old gasoline will build up on certain moving parts, and keep them sealed against engine pressures. Unleaded gas is not good for this type of engine, at all.
A leaded gasoline is one that has a lead-containing compound in it. For many years the number one anti-knock agent was tetra-ethyl-lead. After epidemiological research showed that the lead dust coming from car exhausts was a major cause of lowered intelligence in children the use of this chemical was quickly phased out. The use of any lead compound in gasoline has been a Federal offence for some years now. Leaded gasoline is still available as a high octane aviation gasoliine.

He found lead to increase octane leaves in gasoline
It's found in quite a few compounds.
Lead and oxygen are the elements in lead dioxide.
When gasoline was leaded prior to 1995 (US) the combustion of gasoline containing lead tetraethyl was helped along by the addition of an organobromine compound, 1-2 dibromoethane, that formed lead bromide in combustion , which came out in the exhaust gas. Hardly a use but that was probably the only time most people would encounter this chemical.
Lead is an element
In 1921, at the direction of Dupont Corporation the maker of tetraethyl lead, Thomas Midgley Jr. found the compound to be an effective antiknock agent, while working under Charles Kettering of General Motors Corporation's Dayton Research Laboratories. Midgley nearly killed himself from lead poisoning after over a year of working with the compound and took a prolonged vacation in 1923 to Miami, Florida for convalescence.
All gasoline ever produced starts out as unleaded. Lead was once added later after refining to control pre-ignition and detonation. There is no way to remove lead from gasoline that already has lead in it.
