Features

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 204ºC (400 ºF).  The evaporation rate at these temperatures is low enough to prevent excessive loss of volume.  Key features and benefits include:

FeaturesAdvantages and Potential Benefits
Excellent thermal and oxidation stability Reduces the formation of carbon and sludge deposits
Maintains engine efficiency and extends engine life
Excellent wear and corrosion protection Extends gear and bearing life Reduces engine maintenance
Retains viscosity and film strength across wide temperature range Provides effective lubrication at high operating temperatures
Chemically stable Reduces evaporation losses and lowers oil consumption
Low pour point Eases start-up in low ambient temperature conditions
Applications
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 is also recommended for aircraft-type gas turbine engines used in industrial or marine applications. Mobil Jet Oil II is approved against the Standard Performance (STD) classification of U.S. Military Specification MIL-PRF-23699. It is also compatible with other synthetic gas turbine lubricants meeting MIL-PRF-23699. 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.
