Gasoline,  also spelled gasolene, also called gas or petrol, is used worldwide primarily as a fuel in internal combustion engines. Gasoline is a complex mixture of hundreds of different hydrocarbons. Most are saturated and contain 4 to 12 carbon atoms per molecule. Gasoline used in automobiles boils mainly between 30° and 200° C (85° and 390° F), the blend being adjusted to altitude and season. Aviation gasoline contains smaller proportions of both the less-volatile and more-volatile components than automobile gasoline. The characteristic of a particular gasoline blend is to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) and it is measured by its octane rating. Within our gasoline trading activity we can provide octane range of 85 to 98 RON, gasoline grades, which meets the various specification.
