2380 – Eastman™ P3435903 Turbine Engine Oil 1 Quart
Available now on the Airparts.aero Marketplace.
Overview
Eastman™ Turbo Oil 2380 is a flight-critical, high-performance synthetic turbine engine oil, representing one of the most widely used and trusted lubricants in the aviation industry. This is not a standard oil; it is an advanced, 5 centistoke (cSt) synthetic lubricant engineered by Eastman from a polyol ester base stock combined with a proprietary package of additives. The Turbo Oil 2380 is designed to provide exceptional thermal and oxidative stability, superior wear protection for high-load gears and bearings, and reliable performance across the extreme temperature and pressure ranges of modern gas turbine engines.
Qualified under the stringent U.S. Military Specification MIL-PRF-23699F STD (Standard), this oil is the specified lubricant for a massive range of turboprop, turbofan, and turboshaft engines found on commercial airliners, business jets, and helicopters worldwide. Its integrity is fundamental to the reliability and longevity of the engine.
Key Features
Exceptional Thermal & Oxidative Stability: The synthetic polyol ester base stocks and advanced antioxidant additives provide superior resistance to thermal breakdown and oxidation at the extreme temperatures of a turbine engine's hot section. This minimizes the formation of harmful coke, sludge, and varnish deposits, keeping the engine's oil system clean.
Superior Load-Carrying Capability: Formulated with anti-wear and extreme pressure (EP) additives, it provides a robust lubricating film that protects high-load components like reduction gearbox gears and high-speed bearings from scoring and wear.
Wide Operating Temperature Range: Engineered to perform flawlessly across an extremely wide temperature range, from the low temperatures of a high-altitude cold soak to the intense heat of the turbine bearings, ensuring reliable lubrication in all phases of flight.
Corrosion & Rust Inhibition: The additive package provides excellent protection for all engine metals, including steel, copper, and bronze, guarding against rust and corrosion during operation and periods of inactivity.
Military Specification Qualified: Fully qualified and approved under MIL-PRF-23699F STD, ensuring it meets the highest performance and quality standards demanded by global military and commercial aviation authorities.

Why Choose Eastman™ Turbo Oil 2380?
The lubrication system is the lifeblood of a multi-million dollar turbine engine. A failure of the oil to lubricate or cool critical components can lead to a catastrophic, uncontained engine failure. Eastman™ Turbo Oil 2380 is a globally trusted, military-specification lubricant with millions of flight hours of proven performance. Using a certified, OEM-approved oil is the only way to ensure your engine is protected by a fluid with the correct viscosity, thermal stability, and additive package required for safe and reliable operation.
Eastman™ Turbo Oil 2380 is formulated with polyol ester base stocks, a type of synthetic lubricant created through the reaction of an alcohol and an acid. Unlike mineral oils, which are refined from crude oil and contain a wide range of hydrocarbon molecules, synthetic esters are built from the ground up to have a very uniform molecular structure. This uniformity is what gives them their superior properties. The ester molecules have a natural polarity, meaning they have a slight electrical charge. This causes them to be attracted to and form a strong, resilient film on metal surfaces, providing excellent "boundary lubrication" protection during engine start and shutdown when full hydrodynamic lubrication is not yet established. The absence of wax in the synthetic base stock also gives it its exceptional low-temperature fluidity, ensuring oil can be pumped to critical components even after a cold soak at high altitude.
Note: This is a flight-critical engine lubricant. Always consult the specific aircraft or engine maintenance manual to ensure this is the correct, approved oil for your application. Do not mix with other oil types unless explicitly permitted by the engine manufacturer. Refer to the Material Safety Data Sheet (SDS) for complete safety and handling information.
