The document summarizes the results of a field test comparing a standard hydraulic fluid to a Hydrotex hydraulic fluid on a Caterpillar 318C L excavator. Over nine days of operation, fuel consumption was measured with each fluid at different engine throttle settings. On average, the Hydrotex fluid provided a 3-5% fuel savings compared to the standard fluid. Specifically, on days with the Hydrotex fluid the excavator consumed 3-5% less fuel than when using the standard fluid under equivalent operating conditions.

1. INVESTMENT GRADE ENERGY EFFICIENCY WITH A QUICK R.O.I.
• Zinc containing additive system to meet Caterpillar® specification for anti-wear hydraulic fluids.
• Extreme low pour points: -59˚ F for ISO 32.
• Extremely high Viscosity Index (VI): ISO 32 – 160 VI resists thickening in cold temperature and thinning in high temperature.
Hydrotex® additive supplier conducted the following field test with
Hydrotex Fuel Saving Hydrosynthetic® Hydraulic Fluid.
