Eastman Turbo Oil 2197 exhibits best-in-class performance in reducing critical vent tube coking.

Currently, due to the high performance capable (HPC) oil being used, Dare MedFlight is required to clean the engine vent lines on the two engines of its BK-117 helicopter every 15–20 service hours. This can be a tedious and time-consuming process, and as a rapid medical transportation provider, time is of the essence for Dare MedFlight.

The challenge

Demonstrating the significance and benefits of oil performance in reducing engine coking in CFM56-5B engines

The solution

Eastman Turbo Oil 2197™ is 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.

Eastman Aviation Solutions participated in an oil systems review of a Juneyao Airlines CFM56-5B in which Eastman Turbo Oil 2197 has been used exclusively since the engine’s entry into service in December 2006. The engine accumulated 30,312 hours and 15,080 cycles since new and was removed for scheduled performance restoration and core section life-limited parts (LLP) replacement.

Considering the extraordinarily high time on the engine and its 2:1 hour/cycle ratio usage, the engine oil system was exceptionally clean and free of oil-derived deposits.
