The invention concerns a method for determining the dilution in fuel of a heat engine oil, characterized in that it comprises the following steps: measuring the electrical resistance (R<SUB>0</SUB>) and the electrical capacitance (C<SUB>0</SUB>) of an oil sample to be evaluated, comparing the pairs of values (R<SUB>0</SUB>, C<SUB>0</SUB>) thus measured with a first reference curve (CR1) corresponding to the evolution of the resistance (R) as a function of the capacitance (C) for an oil without fuel dilution, recording the difference (?R) between the measured resistance value (R<SUB>0</SUB>) and the reference curve (CR2) for the measured capacitance (C<SUB>0</SUB>), plotting the resistance difference (?R) thus obtained onto a second reference curve (CR2) corresponding to the evolution of the resistance (R) based on the dilution in fuel (D) and retaining the dilution value (D<SUB>0</SUB>) of the second reference curve (CR2) corresponding to the plotted resistance difference (?R). |
