ExxonMobil aviation , Finland
Product Description
Mobil Jet™ Oil CI is a high performance aircraft-type gas turbine lubricant, based upon the proven Mobil Jet Oil II formulation technology that has been updated to include additional additives for improved protection against rust and corrosion in severe operating environments. It is fully qualified against the Corrosion Inhibited (CI) classification in the MIL-PRF-23699 specification and approved for use in military and commercial applications that require this level of performance.
Features and Benefits
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, including severe salt water corrosive environments.

Applications
Mobil Jet Oil CI 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 where additional protection against salt water corrosion is required. Mobil Jet Oil CI is approved against the Corrosion Inhibited (CI) 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 CI. Mobil Jet Oil CI 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.
