Eastman Turbo Oils
Eastman™ Turbo Oil 2197
Eastman™ Turbo Oil 2197 is designed to exceed the demands of current and future jet engines. With over 300 million hours of in-flight experience, it is by far the most widely used HTS fleet oil in the world. Eastman™ Turbo Oil 2197 is manufactured in our own facility so you can rely on consistently high quality wherever you are in the world.
Eastman™ Turbo Oil 2197 is AS5780 HPC / MIL-PRF-23699 HTS class, 5 cSt turbine oil for the most thermally demanding engine and accessory applications.
Eastman™ Turbo Oil 2380
Eastman™ Turbo Oil 2380 is still one of the most widely used turbine oils in the commercial aviation industry. It was one of the first turbine oils to be qualified and approved for Mil-PRF-23699 STD (Standard) class and subsequently SAE AS5780 SPC (Standard Performance Capability) class.
If you’re looking for exceptional accessory performance then Eastman™ Turbo Oil 2380 delivers, with extended on-wing accessories lifespan and improved reliability. Eastman™ Turbo Oil 2380 has also been found to neutralize the effects of Copper (Cu) – with superior metal passivization results showing reduced oxidation and sludge formation.
Eastman™ Turbo Oil 2389
Eastman™ Turbo Oil 2389 is a low viscosity gas turbine oil, offering exceptional cold-start capability.
Many large commercial airlines use Eastman™ 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. Eastman™ Turbo Oil 2389 is the only MIL-PRF-7808 Grade 3 qualified oil that is fully approved in all Honeywell and Hamilton Sundstrand APUs. 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 centistoke oil. It also has load-carrying ability equal to, or better than, other approved MIL-PRF-7808 Grade 3 oils.
Eastman™ Turbo Oil 25
Eastman™ Turbo Oil 25 is a high load-carrying gas turbine oil, for the most demanding gear applications.
Helicopter operators in both military and private sectors have shown a preference for the DOD-PRF-85734 oils, like Eastman™ Turbo Oil 25, because of the wear protection provided by its extreme pressure additive technology. Air Eastman lubricants is the only oil manufacturer to offer broadly used DOD-PRF-85734 and MIL-PRF-23699 HTS Class oils, to suit all your helicopter oil lubrication needs.
Eastman™ Turbo Oil 25 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 extreme pressure additives to maximise gear system reliability.
Eastman™ Turbo Oil 25 is a DOD-PRF-85734, 5 cSt viscosity class oil, plus extreme pressure additives, for the demanding loads of helicopter gearboxes.
Eastman™ Turbo Oil 274
Eastman™ Turbo Oil 274 is now being used by over 50 airlines throughout the world. This represents nearly two-thirds of the world’s commercial requirement for 7.5 centistoke turbo oils. This fact is proof of this product’s outstanding performance in today’s engines and accessories.
Eastman™ Turbo Oil 274 is a DEF STAN 91-98 oil in the 7.5 cSt viscosity class, uniquely suited for older turboprop applications, such as the R-R Dart.
The popularity of Eastman™ Turbo Oil 274 is largely due to its good high temperature performance and load-carrying ability. These provide long trouble-free performance under severe conditions
Synthetic oils of this type are not all identical. The advantages of Eastman™ Turbo Oil 274 are achieved only by careful selection and balance of base stocks and additives to provide the desired performance.
Eastman™ HALO 157
For many years MIL-PRF-23699 approved engine lubricants were employed in helicopter gearboxes, thus ensuring a common lubricant for both engines and transmission systems. More recently, high load carrying oils have been evaluated and found to offer advantages over conventional load carrying MIL-PRF-23699 oils. These higher load carrying oils complying with specification DOD-PRF-85734 were, again, originally intended only for engine applications. The two MIL Spec oils are thus of identical viscometric properties. Operators considered that lubrication performance of gearboxes could be enhanced by a higher viscosity, high load carrying lubricant possessing improved corrosion protective qualities.
Eastman™ HALO 157 is a clear amber colored fluid with a faintly aromatic odor reminiscent of turbine engine oils. It is based on selected polyol esters, the inherent characteristics of which are enhanced by additives. also fully compatible and miscible with other oils approved to speciifcations, MIL-PRF-23699 and MIL-PRF-7808.
Multiple testing has been completed in bearing and gearbox rigs and flight evaluations culminating in the NATO standard (AIR STANDARD ACS 4035) for a 9 cSt advanced Helicopter Gear Box Lubricant.
