High viscosity index, excellent oxidative stability and low volatility make synthetic esters the preferred base fluids for jet-engine oils. Aviation turbine engine bearings demand fluidity at extreme low temperatures and lubrication film strength under high shear and high temperature conditions. Esters have been proven to deliver long life, low deposit formation and reliable lubrication under the most extreme operating conditions.
