Features and Benefits
Mobil Jet Oil 387 shows excellent performance controlling deposits typically experienced in both the liquid and vapor phases in bearing compartments, oil supply lines, and breather/scavenger lines. These properties have been confirmed in various laboratory tests, including the Corrosion-Oxidation Stability Test, Alcor Deposition Test, Vapor Phase Coker, Erdco High-Temperature Bearing Test, Ryder Gear, and the Mobil Thin Film Oxidation Test.
The closely controlled viscosity of Mobil Jet Oil 387 at -40°C (-40°F), and a pour point below -54°C (-65°F), ensure the good low-temperature fluidity which permits starting and lubrication at temperatures as low as -40°C. In extensive laboratory testing, Mobil Jet Oil 387 exhibits excellent bulk oil stability at temperatures greater than 225°C (437°F).

Advantages and Potential Benefits |
|
Long-duration fluorocarbon compatibility |
Helps avoid premature or unscheduled engine repairs. Helps prevent leaks that can lead to air craft delays and cancellations. |
|
Outstanding oil life characteristics, such as bulk oil stability, viscosity and TAN control |
Helps minimize formation of sludge and carbon deposits which allows better engine efficiency and reduced engine repair costs as well potentially achieving longer oil drain intervals (in certain applications such as marine and land based turbines), effective lubrication at high operating temperatures |
|
Very low vapor/mist and thin film deposition resistance |
Helps control deposits in air vent tubes, bearingcompartments, and scavenge oil lines which will all result in reduced engine maintenance costs |
|
Good low temperature fluidity |
Permits start-up and ensures effective lubrication of critical components (such as APUs in ETOPS applications) at temperatures as low as -40 °F |
Applications
Mobil Jet Oil 387 is approved against the new SAE AS5780 High Performance Capability (HPC) standard. This civil specification was developed to meet the growing performance and quality needs that commercial airlines seek, especially with the entrance of new, higher-output and lower consumption engines.
OEM in-house evaluation/approval programs are also underway. Once complete, Mobil Jet Oil 387 will be commercialized for use in aircraft gas turbine engines, including turbo-jet, turbo-fan, turbo-prop, and turbo-shaft (helicopter), in commercial and military service. In addition, it will be suitable for aircraft-type gas turbine engines in industrial and marine applications.
Mobil Jet Oil 387 is compatible with other synthetic gas turbine lubricants meeting U.S. Military Specification MIL-PRF-23699. Mixing with other products, however, could result in some loss of its superior performance features. The lubricant is completely compatible with all metals used in gas turbine construction, as well as with F Rubber (Viton A), H Rubber (Buna N), and other commonly used seal materials.

Mobil™ HyJet™ V
Mobil HyJet V is a Type V fire-resistant phosphate ester hydraulic fluid, which is superior in thermal and hydrolytic stability to commercially available Type IV hydraulic fluids. Better stability means the extent of fluid degradation in aircraft systems will be less than Type IV fluids, in-service fluid life will be longer, and consequently aircraft operator maintenance costs may be lower.
