The lubrication properties and wear preventive characteristics of soy bean oil based fatty acid methyl esters(FAMEs) as a lubricating base oil were examined using the four ball tester. The lubrication and wear properties of FAMEs are similar or somewhat better than petroleum base oils. Acid numbers were measured to investigate acidity variation after wear test. Petroleum base oils have shown no change in acid number but there was an increase of acid number for FAMEs after wear test. Particulate formation analysis was performed using membrane filters after wear test. There was no particulate observed for petroleum base oil but black particulate which is thought as soot was observed on the membrane filter of FAMEs.
