In this work we report measurements of resistivity of rapeseed oil. The use of this electrical approach has been made between 25 and 80 ° C. These measurements show that the resistivity decreases as the temperature believes. This decrease in resistivity was attributed to the effect of thermal agitation on the structure of molecules of our oil. This study may be useful for a possible application of our oil in the technological field. The temperature dependence of resistivity of oil Colza is described using an Arrhenius-type equation. We plotted the curves of Logarithm of viscosity versus 1/T for each sample. The activation energy Ea and the infinite-temperature viscosity (η∞) were determined from these plots for our oil, the correlation coefficients is 0.9616.
