Nanoparticles play an important role in improving the performance of engine oil, especially in reducing abrasion. In this research MOS2, Al2O3 and MnO2 nanoparticles used to improve performance and reduce wear properties of lubricant oil. Nanoparticles were added to SN 10W40 oil with different weight fractions. Results of viscosity, flash point and pour point measurements and four-ball tests were compared between lubricant oils contain nanoparticles and lubricant oil without nanoparticles. The results showed that adding MOS2 and Al2O3 nanoparticles improved wear properties while MOS2 had a better effect and adding MnO2 nanoparticles to engine oil improved thermal conduction of SN 10W40 engine oil.
