Eastman Aviation Solutions Announces 400-Million Hour Milestone For ETO 2197 

Eastman Aviation Solutions announces its Turbo Oil 2197™ has achieved more than 400 million engine/accessory hours of successful operation as of August 2017. 

The 400-million hour milestone demonstrates the product's proven performance and trusted reliability throughout the aviation industry. ETO 2197 was designed to exceed the demands of current and future turbine engines, and is the oil of choice for any aircraft that operates on High-Performance Capable (HPC) oils. 

Eastman Turbo Oil 2197™ was the first oil approved to the AS5780 specification providing performance levels that exceeded thermal stability and cleanliness requirements of HPC class within that specification. Approved by leading engine manufacturers for all narrow and wide body commercial aircraft, Eastman Turbo Oil 2197™ is also qualified to MIL-PRF-23699 High Thermal Stability (HTS) class. 

Eastman Turbo Oil 2197 was developed in response to an emerging issue associated with oil-related carbon deposits [referred to as “coking"], which results in restriction or blockage of oil flowing through the bearing chambers, contributing to engine failures and shutdowns. Such occurrences are modeled in the laboratory by expert scientists using proprietary technology including the Aviation Lubrication Advanced Deposition Simulator (ALADS) - a unique specialized testing rig that verified the innovative ideas applied during ETO 2197 development and testing. ALADS testing confirms ETO 2197 performance remains ‘best in class’ among all the latest generation HPC oils in resisting thermal degradation and the formation of harmful coke deposits. 

The ALADS is an environmentally controlled rig configured to accurately simulate harsh engine operating conditions from taxi to take-off and landing, thereby allowing Eastman's expert aviation scientists to study the coking phenomenon and the impact of specific oil formulations. Being able to simulate such conditions off-wing is a very powerful tool, especially during the innovation phase of new oil development. 

"The growth from 300-million hours to 400-million hours has been a significant achievement for Eastman Aviation Solutions in a little over two years. This progression of success further authenticates ETO 2197's continued success as the "industry flagship" for HPC lubricants," says Andrew Markson, Aviation Fluids Technology director. "This milestone validates that ETO 2197 is the surest and cleanest oil for today's higher operating temperature engines," Dr. Markson continues.
