Abstract: The paper deals with the analysis of an impact of standard lubricating additives in Lard oil fatty acid Methyl Ester (LME) on wear reduction characteristics. Wear protection properties of lubricating oils have been tested in a 4-balls tribometer. Application of different functional purpose additives (hydraulic systems oils, transmission oils, biodegradable powersaw chains oils) has been found to have a different effect on wear protection. At low concentrations (0.2...0.8%) in LME the anti-wear additives form local thin coatings on the friction surface only, nevertheless, at such concentrations a powersaw chains additive provides maximal protection. Other additives provide the best performance at their maximal concentrations at which a wear scar is covered by a layer of anti-wear additives. Due to the impact of the additives wear is decreased up to 2.8 and friction losses - up to 1.38 times
