Federal Buyers’ Quick‑Start to Purchasing AeroShell Turbine Oils Through GSA Advantage

Gas turbine engines are pound for pound some of the most powerful engines in the world. Not only are they the most potent engines by pound, but they are also the simplest in theory. But simple does not mean easy; the engine relies heavily on oil, as some parts routinely operate at 10,000-25,000 RPM on the high-pressure side. 

If the turbine engine oil fails or is an improper grade or spec, it can quickly deteriorate the engine and lead to catastrophic failure.

AeroShell is one of the premier manufacturers of high-temperature engine oil, preserving and protecting components with the right blends of additives. 

If you are looking for high-performance turbine engine oils, federal buyers can streamline procurement through GSA Advantage with AeroShell's advanced synthetic turbine oils. These oils deliver exceptional thermal stability and deposit control for demanding gas turbine applications:​

A Brief Introduction to AeroShell Turbine Oils

Turbine engines and aero-derived gas turbines face some of the most severe lubrication operating conditions in the world. As higher operating temperatures and pressures are the norm, lubricants have to withstand extreme temperatures while providing oxidation stability, corrosion resistance, and deposit control. 

Without advanced levels of stability, engines are at a high risk of sludge buildup, varnish formation, and extended wear on critical components like bearings. AeroShell turbine oils are made to combat varnish buildups and other factors that increase wear.

Understanding Turbine Oil Basics

Turbine oil does more than just lubricate. These oils cool high-speed bearings, protect metal surfaces from rust and corrosion, passivate metal to prevent chemical reactions, and control deposits and sludge to keep engines clean.

Modern oils are formulated from synthetic base oils and additives that enhance thermal and oxidation stability, as well as elastomer compatibility with seals and gaskets. Standards like SAE AS5780 and military specification MIL-PRF-23699 (and its predecessor MIL-L-23699) define the performance requirements for turbine engine oils. These specs ensure the oil can withstand higher operating temperatures, pressures, and severe lubricant operating conditions found in commercial and military turbine engines.

AeroShell Turbine Oil 500

AeroShell 500 turbine oil is developed for all types of civil and military engines, APUs, and aero-derivative gas turbines.

Properties: AeroShell 500 offers a viscosity of 5.11 mm²/s at 100°C, a flash point of 264°C, and a pour point below -54°C. It provides strong resistance to sludge and varnish formation and can improve thermal performance by reducing deposits.

Approvals: It is fully approved under MIL-PRF-23699 (Standard Performance Capability), NATO Code O-156, and Pratt & Whitney 521C Type II.

Use Case: AeroShell 500 is a standard performance oil type, proven for corrosion resistance and reliability in a wide range of turbine engines and accessories.

Make sure to fully review the AeroShell 500 TDS for complete characteristics. 

AeroShell Turbine Oil 555

AeroShell 555 turbine oil is well known for helicopter use. It was designed for jet turbine engines, helicopter transmissions, gearboxes, and industrial gas turbines. Its unique additive package provides load-carrying capacity, corrosion protection, and longer life under high mechanical stress.

Properties: High temperature performance, oxidation stability and anti-wear. Viscosity 5.4 mm²/s at 100°C, flash point 260°C, pour point <-54°C.

Approvals: DOD-L-85734A, DEF STAN 91-100, Bell Helicopter and Boeing approval for Chinook.

Use Case: For rotary wing aircraft where transmissions and bearings are under heavy load, AeroShell 555 ensures reliable operation in demanding conditions.

AeroShell Turbine Oil 560

  • Properties: With a viscosity of 5.21 mm²/s at 100°C, a flash point of 268°C, and a pour point of -60°C, AeroShell 560 offers outstanding high-temperature stability and clean-running performance. It reduces sludge and varnish formation and provides longer service life. 
  • Approvals: AeroShell 560 meets MIL-PRF-23699 HTS, NATO O-154, DEF STAN 91-101, and COMAC QPL standards.
  • Use Case: Ideal for high-power commercial and military turbine engines that require low coking, advanced lubrication, and the ability to withstand extreme temperatures.

Comparison: AeroShell 500 vs 555 vs 560

While these three turbine oils are well-suited to their intended purposes, they are also designed to perform other duties across various aircraft types and environments.

Regulatory and Technical Approvals

Military specs MIL-PRF-23699 and NATO codes O-156 and O-154 define the standards for turbine oils. 

Civil specifications, including SAE AS5780, provide commercial fleets the same level of quality standards in testing and engineering as military standards. Approved fluids are required for bearings, accessories, and engine components across fleets. Meeting these specs and testing requirements is critical for both military and civil operators.
