TiO 2 nanoparticles is one of the most studied nanomaterials as an additive in oil lubricant due to its outstanding chemical and physical properties as well as low toxicity. This study aims to investigate the effect of TiO 2 nanoparticles, as additive in renewable palm oil lubricant on the change of viscosity. Viscosity is one of the most vital physical parameters for assessing the performance of lubricant oil. The method for preparation of all samples involved adding of TiO 2 nanoparticles at concentrations of 0, 0.5 and 1.0 weight percentage in lubricants, followed by mixing using ultrasonication method for 30 minutes. Investigation on the viscosity showed that the viscosity of palm oil bio-lubricants is comparable to SAE 0W20 grade lubricant. The viscosity index tends to increase with the concentration of TiO 2 additive.
