Oman Air announces successful results in engine cleanliness

Oman Air chief technical officer Salim Al-Kindy said changing the grade of oil in its Boeing 737s to HPC was a strategic choice which, judging by experience, the airline expects will pay off considerably. 

Lead engineers from the airline have reported consistent improvements during engine shop visits and routine borescope inspections since the conversion, a discovery which has now prompted the airline to follow suit with its 15 Boeing 737s. 

“We originally chose to use Eastman Turbo Oil 2197 in our A330 (Trent 700) and ERJ 175 (CF34) fleets in the hope that HPC oil would give us notable improvements in engine health, and we have been very impressed,” Salim said. 

“Initially, we believed the conversion would be a time consuming and daunting task, however, with a proactive plan in place and support from Eastman, we were able to make the switch relatively quickly and easily,” added Salim. 

“We expect that changing our 737s over to Eastman Turbo Oil 2197 will particularly help us to avoid coking in the rear oil sump tube which can block oil flow to the No.4 and No.5 bearings,” said Salim. 

“We have accumulated significant experience with Eastman Turbo Oil 2197, operating in a variety of conditions and we are very happy with the performance of the oil,” concluded Salim. 

Eastman Aviation Solutions Global Commercial Director Rodger Harris said it wasn’t surprising that more airlines were choosing HPC over standard grade oil.

“It is fantastic to be receiving customer feedback that solidifies our belief in such a valuable product,” Harris said. 

“The feedback we continue to receive from our airline customers validates our longstanding position that HPC is indeed the way of the future,” said Harris.
