Proactively developed to respond to the evolving needs of customers and the industry, Mobil Jet Oil 387 is the most advanced Mobil turbine oil ever developed. Specifically formulated to deliver unsurpassed engine performance, it strikes the perfect balance, providing optimal engine performance and advanced protection for engines and components. It will meet the performance requirements of both current and future, advanced gas turbine engines used in commercial and military service.
Made from a specially prepared, ester base stock, Mobil Jet Oil 387 is fortified with a unique chemical additive package. The resulting lubricant has superior thermal and oxidation stability that resists deterioration and deposit formation. It delivers a balance that has never before been achieved with a turbine oil, raising the bar in jet engine lubrication.
Mobil Jet Oil 387 is approved for use in an array of engine models and components.
Features
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).
Benefits
Long-duration fluorocarbon compatibility: Helps avoid premature or unscheduled engine repairs. Helps prevent leaks that can lead to aircraft 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, bearing compartments, 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
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.
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.
