Mobil® Jet Oil II Aircraft-Type Gas Turbine Lubricant

Description Mobil Jet Oil II gas turbine lubricant is a combination of a highly stable synthetic base fluid and a unique chemical additive package. The combination provides outstanding thermal and oxidative stability to resist deterioration and deposit formation in both the liquid and vapor phases, as well as excellent resistance to foaming.

The effective operating range of Mobil Jet Oil II is between -40° C and 204° C (-40° F and 400° F). Pour point is -54° C (-65° F). 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.

Application Mobil Jet Oil II is recommended for aircraft gas turbine engines of the turbo-jet, turbo-fan, turbo-prop, and turbo-shaft (helicopter) types in commercial and military service. It also is recommended for aircraft-type gas turbine engines in industrial or marine application.

Mobil Jet Oil II is approved against U.S. Military Specification MIL-L-23699C, as well as by the following engine and accessory manufacturers:

Engine Approvals - Textron-Lycoming - Allison Engine Co. - General Electric Company - Pratt & Whitney Group, United Technologies Corp. - SNECMA - Pratt & Whitney, Canada - Rolls-Royce Limited - Garrett Turbine Engine Co. Accessory Approvals - AiResearch - Auxiliary power units and air cycle machines - Hamilton Standard Division, United Technologies Corp. - Starters - Sundstrand Corp. - Constant-speed drives and integrated-drive generators - Westinghouse Aerospace Electrical Division - Generators

Mobil Jet Oil II is compatible with other synthetic gas turbine lubricants meeting MIL-L-23699E. 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.

Advantages - Reduces formation of carbon and sludge deposits - Reduces engine maintenance - Lengthens gear and bearing life - Lowers oil consumption
