Hydraulic Fluids Product Data castrol.com/GPS 800 255 4417 May 2025 GPS Castrol ® Blue Hydraulic Plus ™ Castrol Blue Hydraulic Plus performed exceptionally well in ASTM D 2619. With an allowable copper weight loss of .2 mg maximum, Castrol Blue Hydraulic Plus 46 had only .09 mg copper weight loss. For water acidity, Castrol Blue Hydraulic Plus had an acidic reading of 0, mg KOH while the test limit was 4.0 maximum. Cincinnati Milacron ermal Stability Castrol Blue Hydraulic Plus received a copper rod rating of 1.5, a steel rod rating of 1 and a sludge rating of 7.2 mg per 100 ml. Sludge (mg/100ml) 1st Test 2nd Test Margin of Safety Margin of Safety Pass Fail 0 10 20 30 40 50 60 70 80 90 100 Thermal Stability (per Cincinnati Milacron Thermal Stability Test) FZG Castrol Blue Hydraulic Plus 46 passes load stage 12 in the FZG test, where as many Dension HF-O grades only meet FZG levels of 10. is ensures that Castrol Blue Hydraulic Plus protects equipment under the most rigorous conditions. Castrol Blue Hydraulic Plus provides excellent pump life and trouble free service in construction and mining mobile hydraulic applications. Castrol Blue Hydraulic Plus possesses proven anti-wear protection, a high viscosity index to enhance performance over a wide temperature range, and excellent water separation properties. Castrol Blue Hydraulic Plus is formulated with carefully selected premium base oils, coupled with rust, oxidation and foam inhibitors. Castrol Blue Hydraulic Plus meets or exceeds the equipment manufacturers' requirements for Vane, Gear and Piston Pumps. e fluid has been dyed a medium blue to facilitate leak detection by the equipment user. Castrol Blue Hydraulic Plus is approved or recommended for the Cincinnati Lamb P-68 and P-70 specifications. In today's mobile hydraulic equipment, such as excavators, bulldozers and drilling equipment, pumps of different types have been incorporated into the same hydraulic circuit in order to achieve outstanding cost effectiveness and efficiency. Castrol Blue Hydraulic Plus will meet the challenge where a common fluid has to be used, which allows vane, gear and piston pumps to work at their maximum rated output.
