Jet engines reach extreme temperatures that put stress on an oil’s performance and its limitations. This can mean costly maintenance and repairs, and safety concerns, if not properly lubricated. One issue recognized in aircraft engines is the impact of coking. “Coking is the build-up of unwanted carbon deposits in the engine, which are formed when oils are placed under high engine temperatures” ( The deposit buildup can block vents, pipes and filters that can ultimately result in engine failure, if not maintained. High quality oils should provide long term protection and high temperature performance that reduce lengthy repairs and downtime. Start with an oil you can trust! 

How can aviation solutions improve performance?

There are standards of functionality required of aviation products to ensure optimal efficiency. “Eastman Turbo Oil 2197™ has proven to reduce or completely eliminate coking in bearing compartments and especially the #5 bearing supply tube on all models of the CFM56 engine, thereby improving maintenance efficiencies and decreasing related costs,” as proven in this Eastman Case StudyOverall, key benefits of Eastman Turbo Oils include: 5 cSt high thermal stability synthetic lubricant, high temperature cleanliness, and outstanding oxidative, thermal and hydrolytic stability.
