Although conventional lubricants such as SAE 20/30/40, machine oils and grease are very popular. The naturally available bio lubricants have been recognized and still there is a scope to explore the various combination of the lubricant to make work as efficient as the with existing lubricant. The nano compounds as additives are chosen predominantly to act as anti-wear, anti-friction, and to handle extreme pressure. Their nanoscale size, thermal stability, diverse chemical compositions, and rapid reactivity with surfaces without requiring an induction period is what that explores them to field of lubrication. These benefits translate into longer operational life for equipment, improved fuel efficiency, and extended maintenance intervals. This article highlights the advantages of nano graphene as emollient extracts and their variations in various path ways of lubrication. Additionally, it focuses on combining it with natural resources to thereby reduce the cost of lube oil. The nano graphene can be synthesized by using CVD, unzipping of CNT, Microwave-assisted exfoliation method, Ball milling method, and green synthesis. This investigation focuses on the different variation and concentration in lubricant oil to explore its rheological and wear properties Keywords: Graphene, Rheometer, Viscosity, IC engines 1.Introduction: Primitive lubrication is an important aspect of any mechanical industry because most of the most machine’s integral part is lubrication. As most of the machines are prone to generate heat and has some grits mixed along with oil contributing to wear and tear. Any industry that aiming in achieving efficiency has to work towards in reducing friction and anti-wear. In order to improve the efficiency of the lubricant oil, the most industrialist are aiming in adding nano additives to the lubricant oil. The main intension is to have smooth flow, lower friction and carry away from the generating medium. The different types of liquid lubrication can be of mineral, synthetic and biodegradable. However, the nation works on naturally and effective utilization of the lubricant as it should leave any waste on the environment nor the affect the atmosphere Effective lubrication is essential for the reliability and efficiency of mechanical systems. Understanding the principles of lubrication and choosing the right type of lubricant for specific applications can significantly enhance performance and longevity. Regular maintenance and monitoring of lubricant condition are also critical to ensure optimal operation. Current Status of Research: There is an era of research that is propagating over the period on materials. Lubrication have existed used either in the form of oil or semi paste as to provide good lubrication to the system. et. al [1] has given an insight on the influence of classes of nanomaterials such as Nano diamonds, ultra-dispersed boric acid and polytetrafluoroethylene (PTFE). And that has proved to enhance the lubricating properties. et. al [2] proved the effect of Nano oil on agricultural engines and performance of eight Massey Ferguson model 399. These oil sample were tested by atomic absorption spectrometry and with Particle Quantifier (PQ), total base number (TBN), viscosity, fuel and water pollution tests. This lubricant as addictive in the system would decrease wear in cylinders, gaskets, drive shafts, gears, cam shaft and valve mechanisms by 68 percent. et. al [3] examined on zinc borate ultra fine powders (ZBUFPs) on their tribological properties as lubricant additives in liquid paraffin (LP). Their effects of surface
