        abstract = {The physicochemical and tribological properties of HP Racer 4 engine oil dissipated with inorganic nanoparticles such as TiO2 were evaluated using a Four Ball Tester. Samples are prepared by dissipating the nanoparticles in engine oil at different weight percentages. These nanoparticles are made stable in the lubricant by adding CTAB as a surfactant. The stability of the lubricant with nanoparticles dissipated in it is evaluated by studying its ultraviolet-visible spectra. Using a Four Ball Tester, the anti-wear and anti-friction properties of the samples are tested, and an evaluation of the TiO2 nanoparticles with surfactants CTAB is done to compare their relative performances. Lubricants' friction and wear characteristics dissipated with nanoparticles vary based on the load applied. It is observed that there is a significant reduction in the coefficient of friction when the base oil is dissipated with TiO2 nanoparticles. The results obtained from this investigation will be used to develop new and efficient lubricants for automotive engine applications},
