Good lubricants possess the properties such as high viscosity index,high flash and fire point, high load carrying capacity, excellent coefficient of friction, good anti-wear capability, low emission into the environment and to enable withstanding high temperatures. Nanoparticles can be used as an additive in the engine oil to improve its lubrication properties to reduce wear and friction of the engine. The purpose of the present research is to add Nickel-carbon coated (NiC) and Nickel oxide (NiO) nanoparticles to SAE 5W30 mineral oil and evaluate the produced changes in some of its properties. Samples were prepared of varying percentage (0.5, 1 and 2 wt %) of nanoparticles in lubricating oil. The antiwear test was conducted using four ball tribotester according to standard ASTM D 4172b.Viscosity and Flash and Fire point test was evaluated using redwood viscometer and open cup tester apparatus according to ASTM standard respectively. The results shows that both nanoparticles as additives in lubricating oil and their combinations improves the tribological properties of the lubricant. This shows that the nanoparticles has the potential of acting as a performance enhancer (additive) in the lubricant. So to achieve better properties determining the appropriate concentration is a very important.

It can be used in many fields and material science into a new era. In recent years numerous investigations have been carried out on the tribological properties of lubricants with different nanoparticles added in it. A large number of papers have reported that the addition of nanoparticles to lubricant is effective in reducing wear and friction .Among those that were added into oils, Ni nanoparticles have received much attention and exhibited excellent applications for their good friction reduction and wear resistance properties . The reduction of wear depends on interfacial conditions such as normal load, geometry, relative surface motion, sliding speed, surface roughness, lubrication, and vibration. In addition, anti- wear properties, load-carrying capacities, and friction reduction are mainly controlled by the chemical additives in lubricating fluid under boundary lubrication conditions. Since stabilization of nanoparticles has been resolved by the addition of a dispersing agent or the use of a surface modification preparation technique, inorganic nanoparticles have received considerable attention in the lubrication field. Nanoparticles have received considerable attention because of their special physical and chemical 2.LITERATURE REVIEW The purpose of this chapter is to present a comprehensive literature review summarizing the previous published work relevant to research work. Numerous nanoparticles have recently been investigated for use as oil additives. Binfa Bongfa et. al. (2015) studied Comparison of lubricant properties of castor oil and commercial engine oil. The tribological performance of crude Nigeria-based castor oil has been investigated and compared with that of a foreign, 20W-50 high quality crankcase oil, to see its suitability as base oil for lubricating oils in indigenous vehicle and power plants engines. The results showed that unrefined castor oil has superior friction reduction and load bearing capability in an unformulated form than the commercial oil hence can be a good alternative base stock for crankcase oils [1] Shubrajit Bhaumik et.al. (2014) investigated the antiwear and extreme pressure properties of multiwall carbon nanotube based mineral oil. The samples were tested for their antiwear and load bearing capacity according to ASTM G99 and ASTM D-2783 standards. The wear test results show a decrease wear in case of multiwall nanotube based mineral oil as compared with pure mineral oil. [2]
