Mobil Jet Oil 254
Mobil Jet Oil 254
This third-generation, high thermal stability (HTS) oil was formulated to deliver exceptional high-temperature thermal stability and improved resistance to deterioration and deposit control versus Standard Type II oils. ExxonMobil Research and Engineering testing showed Mobil Jet Oil 254 lubricant offers excellent resistance to coking and deposit control, and provides exceptional oxidation and corrosion protection. Laboratory tests indicate Mobil Jet Oil 254 provides a 40 percent advantage in higher-temperature bulk oil stability vs. competitive HTS oils tested.
Overall, Mobil Jet Oil 254 delivers improved resistance to deterioration and deposit formation compared to standard Type II oils and can offer.
Reasons to trust Mobil Jet Oil 254
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
Features and Benefits
Mobil Jet Oil 254 is formulated to meet the demanding requirements of latest technology aircraft-type gas turbines operating over a wide range of severe operating conditions. 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. These properties have been confirmed in various laboratory tests including; the Corrosion-Oxidation Stability Test, Alcor Deposition Test, Vapor Phase Coker, Erdco High-Temperature Bearing Test, Ryder Gear and the Mobil Thin Film Oxidation Test.The closely controlled low-temperature viscosity of Mobil Jet Oil 254, along with its low pour point (below -54 ºC), ensure good 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 also exhibits excellent 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.
