Title
(EN) METHOD FOR INCREASING THE VISCOSITY OF AUTOMOTIVE FUEL COMPOSITIONS
Abstract
(EN)

A certain viscosity index (VI) improving additive may be used to increase the viscosity of an autoamotive fuel composition, by an amount greater than that which theory would have predicted to occur to improve the acceleration performance of an internal combustion engine into which the fuel composition is introduced. The fuel composition is suitably a diesel fuel composition, and the additive suitably comprises a block copolymer which contains one or more monomer blocks selected from ethylene, propylene, butylene, butadiene, isoprene and styrene monomers. The additive is preferably used in the composition at a concentration of 0.5 % w/w or lower.
