Lubrication is required to reduce the friction and wear between the parts during the sliding motion. The synthetic lubricants are in present use for this purpose but they are not environmentally friendly. So, an alternative substitute is a demand in the present scenario. This study explores the ability of Nicotiana Tabacum oil for the processing of trimethylolpropane for bio-based lubricant implementations. TiO

nanoparticles have been applied to the chemically altered oil after the chemical modification method. A tribological study was conducted on the pin-on-disk machine. The kinematic viscosity of the oil showed an increase with the chemical treatment and even during the dispersion of nanoparticles, but an enhanced viscosity index was obtained at a concentration of 0.6% of TiO

nanoparticles reported a decrease in the coefficient of friction (COF) and pin wear. Scanning Electron Microscope (SEM) graphs often display improved surfaces when nanoparticles have been applied up to 0.6% of the concentrations due to improved surface lubrication. With a further increment in nanoparticle concentration, more friction and wear of the material occurs. Effective lubrication was achieved at a concentration of 0.6% of the TiO
