1. A process of reducing fuel consumption, the process comprising: operating an internal combustion engine with fuel, said fuel comprisinga polyalkylene glycol of formula I HO-(A-O)p—(CH2CH2—O)m-(A-O)q—H (I)whereinA is a mixture of two different types of alkylene groups A1 and A2 with A1 designatin
1. A process of reducing fuel consumption, the process comprising: operating an internal combustion engine with fuel, said fuel comprisinga polyalkylene glycol of formula I HO-(A-O)p—(CH2CH2—O)m-(A-O)q—H (I)whereinA is a mixture of two different types of alkylene groups A1 and A2 with A1 designating one or more C3- to C4-alkylene groups and A2 designating one or more C8- to C12-alkylene groups, A1 and A2 being arranged randomly or blockwise,m is a number of from 2 to 100 and p and q are each numbers of from 1 to 100. 2. A process for minimization of power loss in an internal combustion engine and for improving acceleration of an internal combustion engine, the process comprising: operating an internal combustion engine with fuel, said fuel comprisinga polyalkylene glycol of formula I HO-(A-O)p—(CH2CH2—O)m-(A-O)q—H (I)A is a mixture of two different types of alkylene groups A1 and A2 with A1 designating one or more C3- to C4-alkylene groups and A2 designating one or more C8- to C12-allylene groups, A1 and A2 being arranged randomly or blockwise,m is a number of from 2 to 100 and p and q are each numbers of from 1 to 100. 3. A process for improving the lubricity of a lubricant oil contained in an internal combustion engine for lubricating purposes, the process comprising: operating an internal combustion engine with fuel, said fuel comprisinga polyalkylene glycol of formula I HO-(A-O)p—(CH2CH2—O)m-(A-O)q—H (I)A is a mixture of two different types of alkylene groups A1 and A2 with A1 designating one or more C3- to C4-alkylene groups and A2 designating one or more C8- to C12-alkylene groups, A1 and A2 being arranged randomly or blockwise,m is a number of from 2 to 100 and p and q are each numbers of from 1 to 100;wherein said polyalkylene glycol of general formula I is present in the fuel in an amount effective for improving the lubricity of said lubricant oil. 4. The process of claim 1, wherein A is arranged randomly. 5. The process of claim 1, wherein the polyalkylene glycol of formula I is obtained by alkoxylation of a polyethylene glycol of formula II HO—(CH2CH2—O)m—H (II)wherein m is a number of from 2 to 100,with 2 to 200 moles of a mixture of two different types of alkylene groups A1 and A2 wherein A1 is one or more C3- to C4-alkylene groups and A2 is one or more C8- to C12-alkylene groups, A1 and A2 being arranged randomly or blockwise,per mole of polyethylene glycol II. 6. A fuel composition, comprising: in a major amount, a gasoline fuel, and,in a minor amount, a polyalkylene glycol, andat least one fuel additive which is different from the said polyalkylene glycol and has detergent action,wherein the polyalkylene glycol is of formula I HO-(A-O)p—(CH2CH2—O)m-(A-O)q—H (I)A is a mixture of two different types of alkylene groups A1 and A2 with A1 designating one or more C3- to C4-alkylene groups and A2 designating one or more C8- to C12-alkylene groups, A1 and A2 being arranged randomly or blockwise,m is a number of from 2 to 100 and p and q are each numbers of from 1 to 100. 7. The fuel composition according to claim 6, wherein the fuel additive which is different from the polyalkylene glycol and has detergent action, is at least one selected from the group consisting of: (Da) mono- or polyamino groups having up to 6 nitrogen atoms, at least one nitrogen atom having basic properties;(Db) nitro groups, optionally in combination with hydroxyl groups;(Dc) hydroxyl groups in combination with mono- or polyamino groups, at least one nitrogen atom having basic properties;(Dd) carboxyl groups or their alkali metal or alkaline earth metal salts;(De) sulfonic acid groups or their alkali metal or alkaline earth metal salts;(Df) polyoxy-C2-C4-alkylene moieties terminated by hydroxyl groups, mono- or polyamino groups, at least one nitrogen atom having basic properties, or by carbamate groups;(Dg) carboxylic ester groups;(Dh) moieties derived from succinic anhydride and having hydroxyl and/or amino and/or amido and/or imido groups; and(Di) moieties obtained by Mannich reaction of substituted phenols with aldehydes and mono- or polyamines. 8. The fuel composition according to claim 6, further comprising at least one carrier oil. 9. The fuel composition according to claim 8, further comprising at least one tertiary hydrocarbyl amine of formula NR1R2R3 wherein R1, R2 and R3 are the same or different C1- to C20-hydro-carbyl residues with the proviso that the overall number of carbon atoms in formula NR1R2R3 does not exceed 30. 10. The fuel composition according to claim 6, which comprises (Da) a polyisobutene a monoamine or a polyisobutene polyamine having Mn=300 to 5000, having at least 50 mol-% of vinylidene double bonds and having been prepared by hydroformylation of the respective polyisobutene and subsequent reductive amination with ammonia, a monoamine or a polyamine, in combination with at least one mineral or synthetic carrier oil. 11. An additive concentrate, comprising: at least one polyalkylene glycol, andat least one fuel additive which is different from the polyalkylene glycol and has detergent action,wherein each of the at least one polyalkylene glycol is a polyalkylene glycol of formula I HO-(A-O)p—(CH2CH2—O)m-(A-O)q—H (I)A is a mixture of two different types of alkylene groups A1 and A2 with A1 designating one or more C3- to C4-alkylene groups and A2 designating one or more C8- to C12-alkylene groups, A1 and A2 being arranged randomly or blockwise,m is a number of from 2 to 100 and p and q are each numbers of from 1 to 100. 12.
