Jatropha oil has been known as alternative substitute for diesel fuel but its potential use as lubricant is not much known yet. Esterified jatropha oil has been successfully synthesized through esterification process to be used as lubricant additives. This study is meant to investigate wear preventive characteristics of esterified jatropha oil as potential renewable lubricant additives. The characteristics were obtained using four ball test configuration. Addition of low percentage esterified jatropha oil to mineral oil is found to have good effect in reducing wear. © 2011 IEEE.
