A novel oil soluble polyether derivative (OSPSA) was synthesized by the mono‐esterification of oil soluble polyether (OSP) with succinic anhydride (SA). The product was characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance, gel permeation chromatography, thermogravimetry, and acid value. The friction test results indicate that OSPSA exhibited obvious improvement on the friction reduction (by 35.7%) and anti‐wear performance (by 50.3%) comparing with the base oil. Additionally, OSPSA was also found to display excellent anticorrosion properties. OSPSA can be used as multifunctional ashless additive to provide excellent lubricity and corrosion protection properties. It can be speculated from the electrochemical experiments that the corrosion inhibition performance of OSPSA is mainly controlled by anode and the corrosion inhibition efficiency can reach 82.9%.
