The aim of the present work is to synthesize and analyze the mechanical properties of a semi solid engine lubricant which is made up of graphite and kaolin as major constituents which are mixed with CNSL (Cashew Nut Shell Liquid) lubricant as the resin. A normal engine lubricant needs to be drained in an average time interval of 3000kms or 6 month time periods since it loses its properties. A very large quantity of engine oils and coolants are disposed in each service station as waste during each day. So it is necessary to increase the durability of lubricant without losing its properties. The heat dissipation properties, viscosity, thermal conductivity, adhesiveness, wear resistance, etc. of this lubricant is also analyzed and studied. © 2025 Elsevier B.V., All rights reserved.
