Mobil Jet 254 24x1qt

Mobil Jet Oil 254 is a third-generation, high thermal stability (HTS) oil, formulated to deliver exceptional high-temperature thermal stability and improved resistance to deterioration and deposit control versus Standard Type II oils. Mobil Jet Oil 254 is recommended for aircraft gas turbine engines of the turbo-jet, turbo-fan, turbo-prop, and turbo-shaft (helicopter) types used in commercial and military service. It is also suitable for aircraft-type gas turbine engines used in industrial or marine applications. Mobil Jet Oil 254 is approved against the High Thermal Stability (HTS) classification of U.S. Military Specification MIL-PRF-23699. When compared to a typical Type II lubricant, Mobil Jet Oil 254 reduces bulk oil oxidation by up to 50 percent and shows deposit control capability 50 F higher. Additionally, the closely controlled low-temperature viscosity of Mobil Jet Oil 254, along with its low pour point (below -54 ºC), ensures excellent low-temperature fluidity to permit starting and lubrication at temperatures as low as -40 ºC. In extensive laboratory testing and in-flight experience, Mobil Jet Oil 254 exhibits outstanding bulk oil stability at temperatures up to 232 ºC (450 ºF) for extended periods. The evaporation rate at these temperatures is low enough to prevent excessive loss of volume. The load-carrying ability of Mobil Jet Oil 254 comes from its synthetic base stock viscosity and, therefore, is not subject to loss from viscosity index additive shear. The lubricant has excellent resistance to foaming.

Offers exceptional resistance to carbon coking and deposit formation, helping operators reduce shop visits and maintenance costs Helps operators reduce consumption costs due to its outstanding evaporative loss properties Offers outstanding engine protection, even under extremely high operating temperatures Provides excellent low-temperature fluidity in startups as low as -40 degrees Fahrenheit Maintains engine efficiency and extends engine life ExxonMobil warrants that at the time of shipment from its facilities the product meets the descriptions and specifications set forth in the relevant product data sheets, which can be found under the Downloads Section on this page and are published on the ExxonMobil Aviation website at https://www.exxonmobil.com/en/aviation/products-and-services/products/mobil-jet-oil-ii.
