Mobil Jet Oil 254 is a third generation, extra high performance, synthetic aircraft type gas turbine oil designed to meet the performance requirements of gas turbine engines used in commercial and military aircraft. This product is specially prepared, formulated from hindered ester base stock and fortified with a unique chemical additive package. The result is a product with superior thermal and oxidation stability that resists degradation and sludge formation while maintaining the physical properties required by constructive and military specifications. The physical properties of Mobil Jet Oil 254 are similar to those of older generation gas turbine lubricants currently available. The lubricant's effective operating range is between -40 ° C (-40 ° F) and 232 ° C (450 ° F).

Its main features and benefits include: therefore, the viscosity index is not subject to loss due to additive shear. The lubricant has an excellent resistance to foaming.
