'''Octane''' is an [[organic compound]] with the [[chemical formula]] {{chem|[[Carbon|C]]|8|[[Hydrogen|H]]|18}}. It is an [[alkane]] with eight carbon [[atom]]s. It is commonly used in fuel. It is the most important part of [[gasoline]], because it is the part that lets out most of the [[energy]] that comes from gasoline when it is burned. A ''high octane'' fuel will be better than a ''low octane'' fuel.
