To provide a gasoline composition containing an oxygen-containing compound, and having a high octane number, low vapor pressure and excellent oxidation stability, and to provide a method for manufacturing the composition.
The gasoline composition contains an olefin fraction by 1 to 20 vol.%, an aromatic fraction by 20 to 50 vol.%, and an oxygen-containing compound content by 1 to 12 vol.%, in which a volume ratio (Ar7/Ar8) of an aromatic fraction (Ar7) having a carbon number of 7 or less to an aromatic fraction (Ar8) having a carbon number of 8 or more is 0.45 or less. Preferably, the composition has a research method octane number of from 98 to 110 and a sulfur content of 10 ppm by mass or less, and further, the oxygen-containing compound contains ethyl tert-butyl ether (ETBE) by 95 vol % or more. The method for manufacturing the gasoline composition by mixing an oxygen-containing compound containing ETBE by 95 vol.% or more with a hydrocarbon base material, is also provided.
