Eastman Turbo Oil 25
Eastman Turbo Oil 25™ is a high load-carrying gas turbine oil, for the most demanding gear applications.
Helicopter operators in both military and private sectors have shown a preference for the DOD-PRF-85734 oils, like Turbo Oil 25, because of the wear protection provided by its extreme pressure additive technology. Eastman is the only oil manufacturer to offer broadly used DOD-PRF-85734 and MIL-PRF-23699 HTS Class oils, to suit all your helicopter oil lubrication needs.
