ETO2389 OIL, TURBINE, EASTMAN #2389 MIL-PRF-7808L Grade 3

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.

Advanced APU performance oil:

• Reduced hard starts—engine can be started at low temperatures without fear of wear issues due to the oil's low viscosity.
• Trusted solution—meets or exceeds the requirements of U.S. Military Specification MILPRF-7808 Grade 3
• Advanced APU performance—provides excellent “cold soak” reliability in aircraft APUs
• Performs well in long periods of severe operation—high-bulk stability offers high resistance to physical or chemical change resulting from oxidation.
