Disclosed is a fuel additive containing a ferrocene component composed of ferrocene and/or a ferrocene derivative, a lecithin and an organic salt component composed of an organic nitrate and/or an organic barium salt. The fuel additive can be divided into a solid component containing the ferrocene component and the lecithin, and a liquid component containing the organic salt component. The solid component is contained in an amount of 1-20% by mass, and the liquid component is contained in an amount of 80-99% by mass. The fuel additive is used in such an amount that, in a fuel, the ferrocene derivative has a concentration of 1-50 ppm, the lecithin has a concentration of 0.01-400 ppm, and the organic nitrate has a concentration of 1-4200 ppm and/or the organic barium salt has a concentration of 0.15-630 ppm in terms of Ba. |
