Abstract (en)
[origin: WO2012076653A1] The use of a viscosity increasing component in an diesel fuel composition is described for the purpose of improving the fuel economy of an engine or of a vehicle powered by such an engine. The viscosity increasing component is a viscosity index (VI) improving additive, such as a polystyrene-polyisoprene stellate copolymer. The diesel fuel may comprise a biofuel. Methods of using a viscosity increasing component for purposes of improving fuel economy, and methods of operating a compression ignition engine are also described,
