Product Information

The combination provides outstanding thermal and oxidative stability to resist deterioration and deposit formation in both the liquid and vapour phases, as well as excellent resistance to foaming The effective operating range of Mobil Jet Oil II is between -40 ºC (-40 ºF) and 204 ºC (400 ºF) Mobil Jet Oil II is engineered for aircraft gas turbine engines used in commercial and military service requiring  MIL-PRF-23699G Type STD level performance. It also is recommended for aircraft-type gas turbine engines in industrial or marine service applications


  • Mobil Jet Oil II is formulated to meet the demanding requirements of aircraft-type gas turbines operating over a wide range of severe operating conditions
  • The product has a high specific heat in order to ensure good heat transfer from oil-cooled engine parts.
  • In extensive laboratory testing and in-flight performance, Mobil Jet Oil II exhibits excellent bulk oil stability at temperatures up to 204 °C (400 °F)
  • The evaporation rate at these temperatures is low enough to prevent excessive loss of volume


  • Mobil Jet Oil II is recommended for aircraft gas turbine engines of the turbo-jet, turbo-fan, turbo-prop, and turboshaft (helicopter) types in commercial and military service Also recommended for aircraft-type gas turbine engines used in industrial or marine applications
  • Mobil Jet Oil II is approved against U.S. Military Specification  MIL-PRF-23699G Type STD
  • Also compatible with other synthetic gas turbine lubricants meeting  MIL-PRF-23699G Type STD
  • However, mixing with other products is not recommended because the blend would result in some loss of the performance characteristics of Mobil Jet Oil II.
  • Mobil Jet Oil II is compatible with all metals used in gas turbine construction, as well as with F Rubber (Viton A), H Rubber (Buna N), and silicone seal materials.
