The invention provides a gas oil composition having a C 10-24 paraffin composition that satisfies the condition represented by inequality (1-2) below, a distillate volume at a distillation temperature of 250°C (E250) of 5-45% and a slow-cooling cloud point of higher than -6.0°C. In inequalities (1-1) and (1-2), n is the carbon number of the paraffin and f(n) is the paraffin composition parameter for the carbon number of n represented by formula (2) below. In formula (2), n represents an integer of 10-24, and a, b and c respectively represent the proportion (in terms of molar value) of normal paraffins with carbon number of n, of isoparaffins with carbon number of n and one branch and of isoparaffins with carbon number of n and two or more branches, with respect to the total amount of paraffins with carbon number of n.
