Chemical reagents such as Lithium base grease, Calcium base grease, Aluminum base grease which are reduced the mechanical friction and increase the performance of machines with adding various additives molybdenum disulphide (MoS2), Graphite, Boron Nitrite. Dropping point is an indicator of heat resistance of the grease. The dropping point indicates the upper temperature limit at which grease retains its structure. If, failure the grease against high temperature then occurs friction and increase load. When load is increase then the fuel engine does not give the satisfy output. The paper estimated the dropping point of those grease. A.S.T.M standard D-566 used for estimated dropping of the greases. The dropping point of Lithium base grease, Calcium base grease, Aluminum base grease are estimated 195°C, 95°C, and 110°C respectively. The dropping point of mixed base grease i.e., Calcium 50% + Lithium 50%, Lithium 50% + Aluminum 50% and Calcium 50% +Aluminum 50% are 140°C, 158°C and 152°C respectively. The dropping of mixed base grease is higher than the individuals of the greases. The use of the calcium base grease also act is a water and repellant and corrosion protective. This paper represents that Aluminum 50% + Calcium 50% mixed base grease is showing the best performance against high temperature with protects the corrosion.
