    • A liquid fuel composition comprising: (a) a base fuel suitable for use in an internal combustion engine; (b) a first fuel additive selected from one or more viscosity control agents having: (i) a kinematic viscosity at 100°C of 27 cSt or less; and (ii) a NOACK volatility at 250°C of 100 %wt or less; and (c) a second fuel additive selected from one or more friction modifiers. The present invention further provides a method of improving the fuel economy performance of an internal combustion engine, said method comprising fuelling an internal combustion engine containing an engine lubricant with a liquid fuel composition comprising: (a) a base fuel suitable for use in an internal combustion engine; (b) a first fuel additive selected from one or more viscosity control agents having: (i) a kinematic viscosity at 100°C of 27 cSt or less; and (ii) a NOACK volatility at 250°C of 100 %wt or less; and (c) a second fuel additive selected from one or more friction modifiers.
