%X In this paper viscosity index of hydraulic oil was determined using tree methods. Viscosity index was calculated from the measured viscosity at 40ˇăC and 100ˇăC using ASTM Method D 2270 and was graphically determined using ASTM D 341. Viscosity index calculation was performed with a computer program using kinematics viscosity at 40ˇăC and 100ˇăC. The viscosity-temperature coefficient was calculated from the measured viscosity at 40ˇăC and 100ˇăC.
