WebNote: The compatibility charts should be used as a reference only.Compatibility testing is the only way to verify compatibility. A significant portion of grease lubrication failures can be attributed to mixing greases in a system without taking into consideration compatibility. Different thickener systems can react with each other to modify WebISO-VG viscosity grades for industrial lubricants. The diagram below indicates the minimum and maximum viscosities in centistokes for equivalent ISO-VG grades at temperature 40 o C. ISO VG stands for "International Standards Organization Viscosity Grade" and is a number ranged from 2 to 1500.
