A lubricant (Lithium-Sodium) of Syrian petroleum-based stocks and thickener material depends in its preparation on Skinless chicken fat, was manufactured at different ratios. A study of physical - chemical properties of manufactured grease types was carried out (compared with Syrian standard specification 791/2008) by using standard methods which included: grease state, penetration degree, drop point, free acidity (as oleic acid)% by weight, grease resistence to water, evaporating at 90° C, and corrosion of copper plate.
