This disclosure relates to a low viscosity lubricating turbine oil having a composition comprising a lubricating oil base stock, as a major component, and one or more lubricating oil additives, as minor components. The lubricating turbine oil has a kinematic viscosity of about 16 cSt to about 22 cSt at 40&#xb0; C., a density of about 0.8 g/ml to about 0.9 g/ml, and an absolute evaporation loss at 150&#xb0; C. of less than about 4%. This disclosure also relates to a method for improving energy efficiency in a turbomachine lubricated with the low viscosity lubricating turbine oil. This disclosure further relates to a method for improving energy efficiency while maintaining or improving deposit control and lubricating oil additive solvency in a turbomachine lubricated with the low viscosity lubricating turbine oil. This disclosure yet further relates to a method for improving solubility, compatibility and dispersancy of polar additives in the low viscosity lubricating turbine oil.
