Mobil Jet Oil 254

An extra high-performance, third-generation synthetic lubricant formulated from a specially prepared hindered-ester base stock and a unique additive package. Operating across a wide temperature range between -40°C (-40°F) and 232°C (450°F), it delivers extreme thermal and oxidative stability to resist oil breakdown and deposit formation at elevated temperatures while offering low foaming tendencies, wear protection, and compatibility with standard Viton A and Buna N seals.

Applications

Turbojet, turbofan, turboprop, and turboshaft (helicopter) engines, as well as industrial and marine gas turbines.
