1. Methods to measure the efficiency of hydraulic equipment were developed and applied to an excavator and to plastic injection molding equipment. 2. Shear-stable, high viscosity index hydraulic fluids offer: 2.1 Significant energy savings 2.2 Potentials for productivity increase 2.3 Reduction of GHG emissions. 3. Cost advantages and emission reductions make the use of shear-stable, high Ⅵ hydraulic fluids very attractive.
