Eastman Turbo Oil 2389 55USG Drum *MIL-PRF-7808L Grade 3

Eastman 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 is the only 3 cSt oil with significant commercial experience based on the same polyol ester technology as contemporary 5 cSt oils, which provides peace of mind if inadvertently mixed with main engine oil.

Eastman Turbo Oil 2389 incorporates a level of technology from Type II (5 cSt) commercial turbine lubricants, making it especially suitable for aerospace applications and as an aviation turbine oil (ATO). One of the characteristic advantages of Eastman Turbo Oil 2389 is the minimum formation of varnish or sludge deposits. Long periods of severe operation are possible without the danger of scavenge pump screen plugging or the corrosion that often accompanies excessive deposits. It has a high resistance to physical or chemical change resulting from oxidation. This permits long periods of severe operation without significant increase is viscosity or total acidity, the two principal indicators of product oxidation.
