In our study, we report measurements of viscosity and density of vegetable oils (Rapeseed and Lio) depending on the temperature before and a fter heating. These measurements were made between 20°C and 80°C, and show that when the temperature increases, the decrease of the viscosity and the density of the Rapeseedoil is very remarkable compared to the Lio oil. This reduction in viscosity and density of Rapeseed oil allowed us to consider that it can be used as biofuel instead of mineral oils when the temperature is reached until 140° C.
