In the present work, tribological study of nano particle based mineral oil has been carried out using pin-on-disk apparatus. Graphite(macro particles), multi wall carbon nano tube(MWCNT) and zinc oxide(ZnO) nano particles are used as additives on weight percentage basis(wt.%). It has been observed that MWCNT based lubricant sample shows significant decrease in frictional properties and wear than graphite based and pure mineral oil at an optimum additive concentration of 0.05wt.%. Flash point, fire point and viscosity also increases with the increase in addition of additives(nano and macro). SEM images shows high roughened surface in case of pure mineral oil and mineral oil with graphite as compared with nanoparticles based lubricant.
