Mobil Jet Oil 387 is the most advanced jet engine oil we have ever developed—specifically designed for today’s and tomorrow’s engine technologies. Formulated to deliver exceptional elastomer compatibility, superior thermal and oxidation stability and advanced deposit control—a balance that has never before been achieved with a turbine oil.

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).

Key features and benefits include:

Features	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

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 approved against MIL-PRF-23699-HTS.
