Physico-chemical characteristics of Pakistani used engine oils
In this study, physicochemical characteristics of Pakistani fresh and used monograde (SAE-40, SAE-50) and multigrade (SAE-20W/50) engine oils have been studied. The samples were analyzed for specific gravity at 60/60°F, kinematic viscosity at 100 and 40°C, kinematic viscosity index, pour point, flash point, total base number, copper strip corrosion and sulphur contents following the ASTM (American Society of...
