1: A method for reducing fuel consumption in operating an internal combustion engine with a fuel, the method comprising:
introducing an alkoxylated polytetrahydrofurane of general formula (I)into the fuel as an additive,
wherein m is an integer in the range of ≧1 to ≦50, m′ is an integer in the range of ≧1 to ≦50, (m+m′) is an integer in the range of ≧1 to ≦90, n is an integer in the range of ≧0 to ≦75, n′ is an integer in the range of ≧0 to ≦75, p is an integer in the range of ≧0 to ≦75, p′ is an integer in the range of ≧0 to ≦75, k is an integer in the range of ≧2 to ≦30, R1 denotes an unsubstituted, linear or branched, alkyl radical having 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 or 28 carbon atoms, R2 denotes —CH2-CH3, and R3 identical or different, denotes a hydrogen atom or —CH3, whereby the concatenations denoted by k are distributed to form a block polymeric structure and the concatenations denoted by p, p′, n, n′, m and m′ are distributed to form a block polymeric structure or a random polymeric structure. |
