Improving the electrical conductivity of mineral oil distillate having water content of less than 150 ppm, involves adding a composition which comprises at least one alkylphenolaldehyde resin and 0.10-10 pbw at least one polar oil-soluble nitrogen compound, based on the alkylphenol-aldehyde resin, in such an amount that the mineral oil distillate has a conductivity of at least 50 pS/m. Improving the electrical conductivity of mineral oil distillate having water content of less than 150 ppm, involves adding a composition which comprises at least one alkylphenolaldehyde resin having formula (A) and 0.10-10 pbw at least one polar oil-soluble nitrogen compound, based on the alkylphenol-aldehyde resin, in such an amount that the mineral oil distillate has a conductivity of at least 50 pS/m. R 5>1-200C alkyl or 2-200C alkenyl, O-R 6> or O-C(O)-R 6>; R 6>1-200C-alkyl or 2-200C-alkenyl; n : 2-100. Independent claims are also included for: (1) improving the electrical conductivity of mineral oil distillate having a water content of less than 150 ppm, and comprising 0.1-200 ppm of at least one polar, oil-soluble nitrogen compound, comprising adding to the mineral oil distillate 0.1-200 ppm of at least one alkylphenol-aldehyde resin (A), so that the mineral oil distillate have a conductivity of at least 50 pS/m; and (2) mineral oil distillate having an aromatics content of less than 21 wt.%, a water content of less than 150 ppm, and a conductivity of at least 50 pS/m, and comprising 0.1-200 pm of at least one alkylphenol-aldehyde resin (A).
