Eastman Turbo Oil 2389

Eastman Turbo Oil 2389 – Low-Temperature Turbine Oil

Eastman Turbo Oil 2389 is a 3 cSt synthetic oil that excels in extremely cold operating conditions. While Type III oils are specialized, 2389 is widely used in engines and APUs (Auxiliary Power Units) requiring low viscosity and excellent low-temperature fluidity, especially for aircraft operating in arctic or high-altitude environments. Its superior cold-start capabilities ensure reliable engine ignition and lubrication from the lowest temperatures.

Key Features:

• Excellent Low-Temperature Performance: Specifically designed for extreme cold starts.
• Low Viscosity: 3 cSt at $100^{\circ}C$ provides optimal flow properties.
• High Purity: Designed for use in critical engine systems and APUs.
• Thermal Stability: Maintains lubricating film integrity across a necessary operating range.
