What damage is likely to occur if an aircraft reciprocating engine that is designed to use grade 100 fuel is operated with grade 80 fuel?

What is meant by detonation in an aircraft reciprocating engine?
Detonation is an uncontrolled burning of the fuel in the cylinder of an engine. It is an explosion, rather that a smooth burning
What is the danger of using fuel that vaporizes too readily?

A fuel with a heavy kerosine base, a flash point of 110-150 a freezing point of -40 f, and a heat energy content of 18,600 Btu/pound.
What are two functions of tetraethyl lead that is added to aviation gasoline?
It increases the critical pressure and temperature of the fuel, and it acts as a lubricant for the valves.
What documentation is required for a certificated aircraft to legally operate on automotive gasoline?
