Avgas and jet fuel are not the same thing. Avgas is 100 octane (some as low as 80) gas used in internal combustion engines. Octane is loosely defined as the ability to wait for the spark. That's why lower octane can make your engine ping or knock and effect mileage. Lower compression requires lower octane and many engines can run on as little as 70.
Jet fuel is refined kerosene with additives used in turbine engines. The additives keep it from freezing at altitudes.
Lead was added to gas to cushion the valves and prevent wear. Today's engines use different alloys to get around not having lead in the gas.
Originally, iodine was used as an anti-knock agent.
