The paper investigates the lubricating properties of epoxidised canola oil. The epoxidation is carried out to decrease the unsaturated bonds present in canola oil. Further, metal dichalcogenide nanoparticles (molybdenum disulphide and tungsten disulphide) are mixed in modified canola oil and their effect on rheological and tribological properties is evaluated. The tribological investigation is carried out on a pin-on-disc tribometer with aluminium alloy and steel as tribopairs. The rheological properties of nanofluids have been studied. It is observed that the modification of the canola oil improves the tribological properties of virgin canola oil. The addition of nanoparticles into the modified canola increases the viscosity of the oil with a 1 wt% concentration of nanoparticles. Further, enhancement in the tribological properties is observed with the addition of nanoparticles. A maximum of 54.6% and 30% decrease in coefficient of friction is observed with the use of tungsten disulphide and molybdenum disulphide nanoparticles, respectively.
