What is gasoline made of?

Gasoline is a complex mixture of hydrocarbons, primarily alkanes (paraffins), cycloalkanes (naphthenes), and alkenes (olefins). These hydrocarbons typically contain between 4 and 12 carbon atoms per molecule. The exact composition varies depending on the crude oil source and the refinery process used. In addition to hydrocarbons, gasoline also contains small amounts of additives to improve performance, such as:

* Oxygenates: Increase octane rating and reduce emissions (e.g., ethanol, MTBE).

* Detergents: Keep the engine clean.

* Antioxidants: Prevent fuel degradation.

* Corrosion inhibitors: Protect fuel system components.

* Dyes: Identify different grades of gasoline.

It's important to note that the exact proportions of these components are proprietary to the refinery and vary based on factors such as season and local regulations.
