Product Information

Eastman Turbo Oil 2380 is a synthetic 5 cSt turbine lubricant formulated for the demanding operating conditions of aircraft gas turbine engines and accessories. Eastman describes the formulation as providing a balance of low-temperature viscosity, load-carrying ability, cleanliness and elastomer compatibility.

The oil's load-carrying performance is particularly important for bearings and gear systems. Eastman's typical data reports 99% load-carrying ability at 2,000 rpm and 86% at 6,000 rpm using the IAE Gear Machine reference oil method.

Eastman also identifies copper passivation as an important performance characteristic. The oil has been found to help neutralize the effects of copper, reducing oxidation and sludge formation and supporting accessory reliability.

Frequently Asked Questions

What is Eastman Turbo Oil 2380?
