- Eastman (Formerly Air BP) Turbo Oil 2389 is approved against US military specification MIL-PRF-7808L grade 3 and incorporates a level of technology from Type II (5 cSt) commercial turbine lubricants.
Applications & Approvals
This lubricant combines the thermal and oxidation stability of our commercial 5 cSt synthetic lubricant, Eastman (Formerly Air BP) Turbo Oil 2380, with the ability to flow at extremely low environmental temperature. In addition, it has gear-carrying ability equal to or better than other approved MILPRF-7808L Grade 3 oils.
Eastman (Formerly Air BP) Turbo Oil 2389 thus affords the military operator the lower viscosity advantage of MIL-PRF-7808L Grade 3 oils while providing the higher quality advantages of the Type II commercial oils, especially with respect to better thermal and oxidation stability.
Eastman (Formerly Air BP) Turbo Oil 2389 has been approved by a wide range of engine and accessory manufacturers for their applicable equipment, including: Rolls-Royce Ltd, Rolls-Royce Allison, GE, Pratt & Whitney, Pratt & Whitney Canada, Honeywell, Hamilton Sundstrand, CFMI, MTU, Solar and Turbomeca.
