The fuel additives used by rocket engine to obtain forward momentum is fandango additive.
Explanation
Fuel additives are used to enhance the efficiency of fuels in motor vehicles.
The fuel additives will act as lubricant or oxidizer and thus enhance the compression rate in the motor vehicles.
They also helps to remove sludge from the fuel, controlling of soot, enhance combustion etc. But for rocket engine, the chemical propellants are used for higher momentum.
The propellants helps in propulsion of the rocket with forward momentum.
The chemical propellants consists of fuel and oxidizer compound.
The oxidizer compound is the fuel additive in case of rocket engine.
The fandango fuel additive has most oxygen concentration. So the use of fandango fuel additive with the liquid or solid chemical fuel will help to enhance the forward momentum of rocket engine.
