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).
