Hydraulic Fluids Product Data castrol.com/GPS 800 255 4417 May 2025 GPS Castrol ® Blue Hydraulic Plus ™ Castrol Blue Hydraulic Plus meets the most severe industry requirements including the new "hybrid" test from Denison (T6H2OC), which incorporates both vane and piston pumps under wet and dry conditions over 600 hours. Formulated with up to 50% more performance additive than some competitors, Castrol Blue Hydraulic Plus gives a larger margin of safety in key areas of corrosion, oxidation and wear protection. Water Tolerance Castrol Blue Hydraulic Plus deals with water contamination in a number of ways. First, when water enters the system, Castrol Blue Hydraulic Plus' hydrolytic stability keeps the water from causing damaging rust and corrosion to sensitive hydraulic components. Second, aer hydraulic equipment has been shut down for the day, Castrol Blue Hydraulic Plus will effectively demulsify or separate the water and oil. Water can then be drained from the system before the start of the workday. And third, Castrol Blue Hydraulic Plus is able to remain filterable even aer water invasion. Water contamination tends to slow down the filter time of a hydraulic oil. Castrol Blue Hydraulic Plus exhibits excellent filterability aer 2% water has been introduced into the oil. In recent years, many original equipment manufacturers have reported that some commercial hydraulic fluids have caused field failures when contaminated with water. It is important to note that these fluids had previously met the severe performance standards of many pump manufacturers. Castrol Blue Hydraulic Plus Lubricants, which had outstanding performance in many severe OEM pump tests, was subsequently run in modified tests contaminated with 1% water. Results: Still a pass against the standard pass fail criteria. ermal Stability Oxidation and Control Extended high operating temperatures, commonly encountered in hydraulic equipment, can create corrosive acids, allow sludge and varnish to form and excessively thicken oil until its breakdown is inevitable. Castrol Blue Hydraulic Plus has an outstanding additive package that boosts its oxidation resistance. Castrol Blue Hydraulic Plus prevents the formation of harmful deposits and guards against thermal breakdown due to high operating temperatures. As a result, hydraulic equipment runs longer, more efficiently and with less downtime. Safe for Vane, Gear and Piston Pumps Castrol Blue Hydraulic Plus is formulated to meet or exceed the industry standards for vane, gear and piston pumps. Castrol Blue Hydraulic Plus is specially suited for use in mobile hydraulic equipment, like excavators, bulldozers and drilling equipment, that have various types of pumps and a common sump in the same hydraulic circuit.
