Mixed component traction fluids

A lubricating fluid includes a blend of at least two isomers of hydrogenated linear AMS dimers, one of which is a hydrogenated linear AMS dimer having a formula of 2,4-dicyclohexyl-2-methylpentane and another of which is a hydrogenated linear AMS dimer (HLD) isomer having a formula of 1,4-dicyclohexyl-4-methylpentane. The blend reduces viscosities at low temperatures (0°C and lower), without severely lowering high shear stress EHD shear strength (or traction coefficients), and further inhibits foaming issues which are typical in mixtures of very different fluids such as silicones and hydrocarbons combinations.
