Cat Bio HYDO Advanced (Hydraulic Oil)
Cat Bio HYDO Advanced is biodegradable non-toxic hydraulic oil that is recommended for use in hydraulic systems when environmental compliance is required or desired. Cat Bio HYDO Advanced has a renewable content that exceeds 90% and complies with the European Eco-Label. Consult Federal, state, or local authorities for guidance on hydraulic oils environmental requirements in your area.Cat Bio HYDO Advanced is formulated with premium additives and synthetic biodegradable base oil that pass severe qualification testing requirements to provide superior protection for Cat hydraulic systems and hydrostatic transmissions.Cat Bio HYDO Advanced oils allow 6000 hours or higher oil drain intervals for most applications. S O S Services oil analysis is recommended when the oil drain interval is increased to 6000 service hours or higher. In comparison, non-Cat commercial biodegradable hydraulic oils (second choice oils) allow for a maximum 2000 hour oil drain interval. Follow the maintenance interval schedule for oil filter changes and for oil sampling that is stated in the Operation and Maintenance Manual for your machine. Consult your Cat dealer for details.Cat Bio HYDO Advanced performs similar to Cat HYDO Advanced 10 and offers the following benefits: superior protection against mechanical wear, foaming, and corrosion in hydraulic systems and in hydrostatic transmissions. This oil should be used to achieve maximum life and maximum performance from hydraulic system components and from hydrostatic transmissions. Cat Bio HYDO Advanced is preferred in most hydraulic systems and in most hydrostatic systems when ambient temperature is between −30° C (−22° F) and 45° C (113° F). Consult your Caterpillar dealer for details.To gain the most benefit from the improved performance designed into Cat Bio HYDO Advanced oils, when switching to Cat Bio HYDO Advanced oils, cross contamination with the previous hydraulic oil should be kept to less than 3%. Flushing of the hydraulic system is recommended to reduce the cross contamination.Cat Bio HYDO Advanced can be used in hydraulic systems of other Original Equipment Manufacturers (OEM). Refer to your manufacturer requirements for application details.

Note: Non-Caterpillar commercial oils that are acceptable for use in most Cat hydraulic and hydrostatic transmission systems are as a group third choice oils. Within this grouping of third choice oils there are tiered levels of performance.
Cat does not warrant the quality or performance of non-Cat fluids.
The minimum viscosity for commercial alternative oils used in most Caterpillar machine hydraulic systems and in most Cat hydrostatic transmission systems is 6.6 cSt at 100 °C (212 °F) "ASTM D445".If Caterpillar oils cannot be used, oils meeting the following commercial specifications can be used in most Cat hydraulic systems and in most Cat hydrostatic transmission systems:
Engine oils that meet the Cat ECF-1-a, Cat ECF-2, or Cat ECF-3 specifications and have a minimum zinc additive of 0.09 percent (900 ppm)
Biodegradable oils that meet the Cat BF-2 specification
TO-4 specification oils that have a minimum zinc additive of 0.09 percent (900 ppm)Note:
