PROBLEM TO BE SOLVED: To provide a gasoline fuel composition which is hard to become cloudy as compared with conventional gasoline. SOLUTION: In the gasoline fuel composition, the content of aromatic hydrocarbon is 40% by volume or less, the content of saturated hydrocarbon is 40% by volume or more, the relative dielectric constant is 2.10 or less, and the research octane number is 96 or more. A temperature dependency coefficient K of saturated water content, represented by: K=3.5×O+7.3×t+3.3×C9 äO: olefin content (% by volume), t: toluene content (% by volume), C9: 9C aromatic hydrocarbon (% by volume)}, is preferably 250 or less.
