A new series of lubricity improvers for ultra-low sulphur diesel (ULSD) was synthesized starting from methyl oleate through simple chemical reactions. In the first step methyl oleate was epoxidized using formic acid and hydrogen peroxide mixture. Then the epoxide was subjected to esterification using different long chain (C4–C18 alkyl groups) organic acids to get the final diesters. The lubricating property of the newly synthesized diesters was studied by dosing them to ULSD at 300 ppm (wt/vol) concentration. Amongst them, diester LAMOSA derived from stearic acid showed the best lubrication enhancing property at 300 ppm dosage level. The SEM and EDS spectra of the HFRR (high frequency reciprocating rig) specimen also confirms the formation of metal-oxygen interaction supporting the friction reducing properties of LAMOSA. The study reveals that the newly synthesized methyl oleate derived diesters are promising materials as lubricity additives for ULSD.
