Manufacturer's description

Cat HYDO Advanced 20 complements the Cat HYDO Advanced 10 and 30 hydraulic oils, filling the ISO 68 (SAE 20) viscosity grade in the range. It combines premium additives with specially selected, controlled high-quality base oil to provide extended drain intervals and extra protection to hydraulic system components, and Caterpillar describes it as a significant performance breakthrough in hydraulic oil technology, developed through severe qualification testing in the field and laboratory over thousands of hours. Typical values from the Cat technical data sheet include a viscosity of 68 cSt at 40°C and 9 cSt at 100°C, a viscosity index of 110, an FZG gear test result of 12 (ASTM D5182), a pour point of -33°C, zinc content of 0.094% by weight (ASTM D4951), copper strip corrosion of 3 (ASTM D130), a pass on rust protection (ASTM D665 A and B), and oxidation stability of more than 5,000 hours (ASTM D943). Within the Cat HYDO Advanced family, this ISO 68 grade sits between the lighter Cat HYDO Advanced 10 and the heavier Cat HYDO Advanced 30, giving Cat dealers and end users a range of extended-drain hydraulic oils to match different machines and ambient conditions.

Applications

• - Intended use (per safety data sheet): Hydraulic fluid

Performance & benefits

• 6,000-hour extended drain intervals — up to triple the hours of Cat HYDO 10/20/30 — when monitored with Cat S•O•SSM Services every 500 hours.
• Reduces owning and operating costs and increases uptime.
• Enhanced, long-lasting anti-wear protection: specially developed additives form a protective layer on wear surfaces, reducing component wear in high-pressure piston, vane and gear hydraulic pumps.
• Holds water in dispersion via purpose-built emulsifiers instead of separating it out, helping prevent the pump and component damage that separated (and potentially freezing) water can cause.
• Backward compatible, so it is the only hydraulic oil needed for maintenance stocking; the preferred fill for Cat equipment.
• Improved filtration properties: detergent dispersants keep components clean and improve contaminant transport through filters; compatible with Cat Ultra High Efficiency filters.
• Improved corrosion protection for metal surfaces, better than most other oils in the Cat line-up.
• Faster air release: Cat HYDO Advanced 10 releases air in under 4 minutes, versus 7-10 minutes for Cat HYDO 10W (ASTM D3427), reducing the risk of cavitation.
• Improved oil stability: a 250% increase in oxidation stability per ASTM D943 makes the oil and its wear protection last longer.
