Mobil Jet Oil 254 from Acculube is a third-generation, extra high performance, synthetic aircraft-type gas turbine lubricant engineered to meet the performance requirements for gas turbine engines used in commercial and military aircraft.
This product is formulated from a hindered-ester base stock and fortified with a unique chemical additive package. The result is superior thermal and oxidation stability that resists deterioration and deposit formation while maintaining the physical characteristics required by builder and military specifications. The physical properties of Mobil Jet Oil 254 are similar to earlier-generation gas turbine lubricants. The effective operating range of the lubricant is between -40°C (-40°F) and 232°C (450°F).
