The increasing number of automotive vehicles around the world is responsible for the emission of great amounts of pollutant gases, which can cause serious damage to environment and to human health. Among the fuels used in light vehicles the gasoline, which is a blend of “n-paraffin, naphthenes, aromatics, n-butane, and some additives”. Some of these groups (aromatics 45-50%) are used to increase the octane number, which is considered as a key factor in the fuel quality. However, the aromatic compounds in this fuel contain benzene rings; A Carcinogenic compound which is proved to cause a lot of serious damage to the human health may cause lung cancer. Also the emissions contain amounts of carbon monoxide (CO), nitrogen oxides ( ) and sulfur compounds which may raise serious environmental problems. So new regulations (Euro 6) were made to determine the safe ranges of each component in the blend.  After the new regulations, the percent of aromatics must not exceed a maximum limit of 35% to keep the benzene rings percent in the blend equal to or less than 1%. In this paper we investigate the effect of adding new compounds to increase the octane number within the safe ranges. This paper presents the high octane number environmental gasoline which is a blend of some products: “Naphthas of hydrotreated and hydrocracking, Reformate, Isomerate, and Ethanol and Isopropyl alcohol as oxygenated compounds”. The paper also illustrates the exact percent of each component in the blend, the research octane number and the motor octane number of the blend, and all the physicochemical characteristics of the blend, reaching the optimum three samples which nearly approach the standard A92 and A95 gasoline blends. Hopefully, this paper will attract the attention and promote seeking a clean air and safe environment for the next generations.
