Quasi-static pressure-dependence equations of density and elastic modulus for lubricant oils were derived up to 5 GPa based on the experimental data from both quasi-static pressure vessel apparatus up to 1.2 GPa and dynamic sound velocity data by Brillouin light scattering measurements up to 5 GPa. Dynamic data were analyzed by applying a viscoelastic model for volume change and quasi-static data were obtained. Examined lubricant oils were 3 naphthenic oils such as traction oils, 5P4E (five-ring polyphenyl ether) and DOS (dioctylsebacate). Lubricant oils whose solidfied pressure is lower than 1 GPa were resulted to show almost the same pressure-dependence characteristics of density and bulk modulus over solidified pressure. Temperature-dependence of these equations found out to be small up to 155℃.
