Abstract

The use of an alkoxylated polytetrahydrofurane of formula wherein m, m′, n, n′, p, p′ and k are integers in the range of ≥1, R1 denotes an unsubstituted linear or branched alkyl radical, R2 denotes —CH2—CH3, and R3 denotes a hydrogen atom or —CH3, as an additive in a fuel for reducing fuel consumption in the operation of an internal combustion engine with this fuel.
