KINGSPORT, Tenn. — Eastman Turbo Oil 2197, a high performance turbo oil, has achieved more than 300 million engine/accessory hours of successful operation, according to company officials.
The newly rebranded Eastman Turbo Oil 2197, formally BPTO 2197, is designed to exceed the demands of current and future turbine engines, and is the oil of choice for many aircraft or rotorcraft that operate on High-Performance Capable (HPC) oils.
It was the first oil approved to the AS5780 specification, and exceeds many of the thermal stability and cleanliness requirements of the High Performance Capable class within the AS55780 specification.
The development of Eastman Turbo Oil 2197 dates back to the early 1990s. At that time, there was a need to address issues associated with oil-related carbon deposits, known as “coking,” which can restrict or block oil flow, contributing to engine failures and shutdowns. Reducing coking can be a key factor in safe and smooth aircraft operation, company officials noted.
Approved by all leading engine manufacturers, Eastman Turbo Oil 2197 is qualified to MIL-PRF-23699 High Thermal Stability (HTS) class.
