If the viscosity grade is not correctly matched to the operating It doesn't matter how good the anti-wear,Īnti-oxidization or anti-corrosion properties of the fluid are, Viscosity is the single most important factor when selecting a Variety of fluids, including multi-grade engine oil andĪutomatic transmission fluid (ATF), in addition to the moreĬonventional anti-wear (AW) hydraulic fluid - provided the Most hydraulic systems will operate satisfactorily using a Hydraulic fluid - getting the viscosity right
