Product Description
Product description
Eastman Turbo Oil 2389™ is a low viscosity gas turbine oil, offering exceptional cold-start capability.
Many large commercial airlines use Turbo Oil 2389 in their auxiliary power units (APUs), because of the reliability it affords this equipment when starting after long, cold-soaks at altitude. Turbo Oil 2389 is the only MIL-PRF-7808 Grade 3 qualified oil that is fully approved in all Honeywell and UTC Aerospace Systems APUs. Turbo Oil 2389 is formulated from synthetic base stocks and advanced technology additives, to provide the combined thermal and oxidation stability properties of commercial Type II lubricants, with the low temperature fluidity characteristics of a 3 cSt oil. It also has load-carrying ability equal to, or better than, other approved MIL-PRF-7808 Grade 3 oils.
Applications/uses
- Aerospace
- Aviation turbine oil (ATO)
Key attributes
- 3 cSt synthetic lubricant
- Cold weather
Applications
- This lubricant combines the thermal and oxidation stability of our commercial 5 cSt synthetic lubricant, Eastman 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 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 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.
