Gasoline or petrol is a petroleum-derived liquid mixture, primarily used as fuel in internal combustion engines. It consists mostly of aliphatic hydrocarbons, enhanced with iso-octane or the aromatic hydrocarbons toluene and benzene to increase its octane rating. Small quantities of various additives are common, for purposes such as tuning performance or reducing emissions. Some mixtures also contain significant quantities of ethanol as a partial alternative fuel.
