In this investigation, the properties of heavy diesel lubricants were enhanced by adding the nano-additives. The purpose of this research is verifying the enhancement of the rheological and thermal characteristics of the lubricating oils by adding the nano-additives, in order to upgrade to the highest level for performance lubricant in the system. The SAE 15W40 (Oil parent) was mixed with two types of nanomaterials (MWCNTs and CuO) at four various concentrations by (0.1, 0.2, 0.5, and 1 % wt.) to prepare the nano-lubricants, studying and comparing their properties with parent lubricants. The results indicated that the thermal conductivity values of (OilMWCNTs) and (Oil CuO NPs ) at 1 wt. % concentration of both additives increased by 23%, 15.3% respectively. Also, the flash point of both nano-lubricants comparison with parent oil increased by (19.54%, 15.9%) respectively. It was concluded that (Oil MWCNTs ) showed higher lubricant’s specification than (Oil CuO NPs ) due to the high surface area of MWCNTs. Hence, the operating properties of lubricating oil much enhanced when scattered the carbon nanotubes and copper oxide NPs.
