1. A method for reducing fuel consumption in an operation of an internal combustion engine with a fuel, the method comprising adding an alkoxylated polytetrahydrofurane of formula (I): to 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 is 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 is —CH2—CH3, and R3 is identical or different, and is a hydrogen atom or —CH3, whereby concatenations denoted by k are distributed to form a block polymeric structure and concatenations denoted by p, p′, n, n′, m and m′ are distributed to form a block polymeric structure or a random polymeric structure. |
