XHVI Hydraulic Oils are specialised premium hydraulic fluids which have been formulated to handle the extremes of operating temperatures, pressures, power densities and fluid flow rates which are associated with very high horsepower hydraulic systems. The oils provide unique, long life operating service characteristics by a combination of anti-wear, detergent and very shear stable viscosity improving additives with proven rust, oxidation, corrosion and foam inhibitors. XHVI Hydraulic Oils ensure excellent filterability with hydrolytic and demulsibility stability.


The anti-wear additives in XHVI Hydraulic Oils ensure special protection where inherently high pressures, power densities and temperatures are experienced with high horsepower hydraulic pumps operating at pressures up to 48,000 kPa (7000 psi). These oils allow hydraulic systems to provide long, trouble-free service when operating with this increased horse-power, increased temperatures, reduced oil reservoir volumes and resultant reduced de-aeration times.

XHVI Hydraulic Oils possess excellent filterability even in the presence of moisture contamination; whereas other lubricants may have deposition products (formed as a result of hydrolytic instability particularly with non-ferrous hydraulic components) which plug filter systems leading to pump starvation, cavitation and ultimately premature equipment wear and failure.

XHVI Hydraulic Oils are multi-grade oils which have smaller viscosity changes with temperature variations than the more conventional fluids. At the very high operating temperatures experienced in high horsepower hydraulic systems, this property results in improved full-bodied, wear reducing, lubricant films compared to the thinned-out fluidity of the more conventional hydraulic fluids. This special viscosity control property is maintained by the very shear stable viscosity improver (VI) incorporated in XHVI Hydraulic Oils, when other lesser VIs would shear down to less wear-protecting thinned-out fluids shortening the life of the hydraulic equipment.

The high aniline point of XHVI Hydraulic Oils ensures excellent compatibility with synthetic rubbers, providing extended life to seals. The powerful oxidation inhibitors of XHVI Hydraulic Oils reduce oxidation so that oil degradation is inhibited, thereby reducing the corrosion related problems of shortened hydraulic fluid life, erratic control valve operation, filter plugging, down time, etc. The anti-foam additive in XHVI Hydraulic Oils ensures any entrained air will quickly separate from the fluids so that wear producing metal-to-metal contact is avoided.

XHVI Hydraulic Oils have multi-metal compatibility with the ability to control wear and corrosion of copper and aluminium alloys used in high performance pumps. Corrosion inhibitors and metal passivators formulated in these fluids prevent corrosion of steels and the previously mentioned more easily attacked metals in severe operating service conditions. While formulated with a low zinc formula, XHVI Hydraulic Oils are NOT recommended for use with silver components as found in Lucas PM pumps. For these situations, use the Hi-Tec Zinc Free Hydraulic Oils.

XHVI Hydraulic Oils are not normally recommended as a lubricant for compressors, circulating systems, bearings, general purpose lubrication and enclosed gears where extreme high-pressure, load characteristics are not required. For these applications, use Hi-Tec Compressor Oils.
