Abstract
Useful hydraulic fluids having low temperature properties comparable to MIL-H-5606 fluids but exhibiting markedly superior fire resistance due to their higher flash points are obtained by blending a two centistoke synthetic hydrocarbon oil obtained from the oligomerization of alpha-olefins with a mono- or diester and polymethacrylate viscosity index improver. The fluids of this invention typically have -65.degree. F. viscosities less than 3000 centistokes, 210.degree. F. viscosities of 3.45 or above, and flash points above 320.degree. F. and are readily formulated with conventional additives.
