Can you use pertol in a rocket?

Jet engines capture ambient oxygen to use as an oxidizer for their fuel. In a sense, an afterburner is somewhat like a rocket, but it still uses ambient oxygen for the oxidizer.

Rockets are different. Since they are designed to travel out of the atmosphere, they must carry both their oxidizer and their fuel.

Many hydrocarbons will work as a rocket fuel including petrol (gasoline), diesel, and even tar. But they must all also have oxygen as a second fuel for the oxidizer.

Solid Rockets have both the oxidizer and fuel built into the same matrix, somewhat like gunpowder.

The "Oxidizer" doesn't have to be oxygen, or even contain oxygen. Nitric Acid has been utilized as an oxidizer in some rocket engines.
