摘要
A novel hydraulic (e.g., a biohydraulic) fluid which has high performance attributes is disclosed herein. Such a novel hydraulic fluid includes a contribution of a range of 10% up to about 85% by weight of at least one of: natural esters, synthetic esters, polyols, a vegetable oil, 1% up to about 40% by weight of polyalphaolefin (PAO), 1% up to about 40% by weight of polyalkylene glycol (PAG), and mixtures thereof, and wherein up to about 10% by weight quantity of one or more additives are introduced to provide desired properties that include at least one of: a high viscosity index, a low pour point, a hydrolytic stability, and an oxidative stability, as part of the hydraulic fluid contribution.
