Eastman Turbo Oil 2380 is a 5 cSt synthetic lubricant that is approved against US military specification MIL-PRF-23699F-STD, and UK specification DEF STAN 91-101/2 (replaced DERD 2499). This lubricant provides a balanced combination of thermal and oxidation stability, load carrying capacity, lower volatility and has the best low temperature flow characteristics of all 5 cSt turbine oils. BP Turbo Oil 2380 is recommended for the lubrication of most aircraft gas turbines and accessories. It is also recommended for the lubrication of aero-derived gas turbines in industrial power generation, offshore and marine applications. BPTO 2380 has been approved by a wide range of engine and accessory manufacturers for their applicable equipment, including: Rolls Royce Ltd, Allison, GE, Pratt & Whitney, Pratt & Whitney Canada, Honeywell, Hamilton Sundstrand, CFMI, IAE, MTU, Solar and Turbomeca, etc. Viscosity: BP Turbo Oil 2380 has the best low temperature viscosity characteristics among all 5 cSt oils. Cleanliness: Minimum formation of varnish and sludge deposits over long periods of use. Seal Material Compatibility: Very benign to commonly used seal materials in gas turbines. Load Carrying Capacity: BP Turbo Oil 2380 is among the best of its class and provides excellent protection to bearings, gears, and other highly loaded lubricated surfaces. Bulk Stability: Its high degree of oxidation resistance permits a long period of operation without significant increase in viscosity and/or total acidity.
