Manufacturer's description

Cat HYDO Advanced 10 - Red and UV Dye is the same premium hydraulic oil formulation as Cat HYDO Advanced 10, supplied with both a red dye and a UV tracer dye so it can be visually identified and checked for leaks under UV light. It combines premium additives with specially selected, controlled higher-quality base oils, developed and qualification-tested by Caterpillar over thousands of hours in the field and laboratory, and is the preferred fill for Cat machine hydraulic systems. Specially developed additives form a long-lasting protective layer on wear surfaces in high-pressure piston, vane and gear hydraulic pumps, emulsifiers keep water held in dispersion rather than letting it separate out, and detergent dispersants improve filtration and keep components clean, while the oil offers faster air release and improved corrosion protection compared with the earlier Cat HYDO 10W. Typical values from the Cat technical data sheet include a viscosity of 42 cSt at 40°C and 6.7 cSt at 100°C (SAE viscosity grade 10W), a viscosity index of 114, a pour point of -39°C, a pumping viscosity of 15,000 mPa·s at -30°C, a pass on rust protection (ASTM D665B) and oxidation stability of more than 5,000 hours (ASTM D943).

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.
