Ionic liquids possess several remarkable properties that make them striking for their use as lubricants for different applications. Isothermal compressibility (or bulk modulus) is a fundamental parameter in the hydraulic fluids field. Therefore, an analysis of the compressibility of different ionic liquids, mineral, synthetic and vegetable oils, as well as water, is presented in this work. Furthermore, thermal expansion coefficient, viscosity and viscosity index of these fluids are also analysed. Copyright © 2013 John Wiley & Sons, Ltd.
