ISO 68 HVI hydraulic oils have a thickness is similar to SAE 20w at operating temperature. Additionally, these high viscosity index (or multi-viscosity) hydraulic fluids are formulated to maintain their ideal viscosity, or thickness, over an extreme range of temperatures. A wider temperature range yields a higher viscosity index number.
We carry ISO VG 68 hydraulic fluid from Chevron, Mobil, Kendall, and Sunoco.
