Paraffinic resins derived from Pennsylvania crude oil are evaluated as viscous lubricants and as blending materials with mineral oils in the preparation of hydraulic fluids and lubricants. The oxidative, thermal, and shear stabilities of the resins and of blends of the resins in mineral oil base stocks have been studied in various rigorous tests from the stand-point of service applications. While the resins provide thickening, the low temperature characteristics of blends show improvement over those prepared with synthetic polymeric additives in that viscosities can be closely approximated on an ASTM viscosity-temperature chart and are unaffected by shearing stresses.
