ISO viscosity VG 46 = Summer in northern US and Canada
ISO viscosity VG 68 = Tropical areas, desert summers, indoor uses
• The following table shows the characteristics of Rando HD 46. You may use this information for
comparison with other brands.
• Some oil manufacturers offer vegetable-based hydraulic oils, which are considered environmentally
friendly (the additive packages are not inert, however). These vegetable-based oils must NEVER be
mixed with mineral-based oils. A complete flush of the hydraulic system must be performed when
changing to this type of fluid. See the list below for a sample of the available oils and viscosities.
