As with aircraft engines, aero-derivative gas turbines (ADGT) are fast-starting, compact and reliable. This makes them ideal for meeting surges in power demand and providing emergency power for critical facilities such as hospitals, and for use in remote areas and offshore applications.
ADGTs operate at high temperatures. Oils unable to cope with this heat can break down to form coke, which can lead to high maintenance costs and even blocked oil pipes and turbine fires. Some high thermal stability (HTS) oils formulated to resist coke formation have poor elastomer seal compatibility compared with standard (STD) oils, which leads to seal degradation and oil loss. So, your choice of oil has an impact on maintenance and oil consumption costs. Similar to their airborne cousins, ADGTs require specialist aero-engine oils.
AeroShell Turbine Oil 560
AeroShell Turbine Oil 560 is approved for use in industrial and marine versions of the Rolls-Royce RB211-22 (Siemens SGT-A35), Avon, Spey, Olympus and Tyne engines, Pratt & Whitney (Mitsubishi and Hitachi Power Systems) GG3/FT3, GG4/FT4, GG8/FT8 (evaluation only) and GG12/FT12 engines, all General Electric LM Series units, some Honeywell
and Turbomeca industrial engines, and certain Solar gas engines.
AeroShell Turbine Oil 560 combines high thermal stability for low coking propensity with good elastomer seal compatibility. AeroShell Ascender provides additional benefits for the latest engines.
Heavily coked components take longer to clean, thus extending planned downtime, and carbon deposits can even block oil pipes and lead to turbine fires and unplanned power outages. AeroShell Turbine Oil 560 is an HTS oil. It keeps components cleaner than STD oils by better resisting thermal breakdown for lower levels of coke formation, as can clearly be seen in the images below.
SPECIFICATIONS AND APPROVALS
AeroShell Turbine Oil 560 is fully approved to:
- n MIL-PRF-23699G HTS grade
- n SAE AS 5780B SPC grade.
A COMPREHENSIVE RANGE
We can provide a full range of products and services for your ADGT, including:
- n Shell Turbo T for the generator and gearbox
- n Shell Tellus S2 MX for the hydraulic starter
- n the Shell LubeAnalyst oil condition monitoring service.
WHAT OUR CUSTOMERS SAY
“We have successfully used AeroShell Turbine Oil 560 in our GE LMS100 ADGT since 2012. This application requires a product that meets MIL-PRF-23699. The specification has two options: standard and high thermal stability oil.
We selected AeroShell Turbine Oil 560 high thermal stability oil for our first fill based on its benefits of improved thermal stability, low coking propensity and good elastomer compatibility.
AeroShell Turbine Oil 560 has provided proper compatibly with all seal materials. We are pleased with the performance and confirm that there have been no oil-related problems. We continue to use AeroShell Turbine Oil 560 and have a positive experience of working with Shell.”

AeroShell Turbine Oil 500
Shell has been supporting aviation’s pioneers for over a century and has been involved in jet-powered flight since helping Sir Frank Whittle to develop the first jet engine. We continue to provide high-quality fuels, lubricants and associated services to the aviation community. We remain committed to working with turbine engine manufacturers and airlines to create innovative high-performance oils for increasingly demanding engines.
A TURBINE ENGINE OIL (TEO) THAT MAY HELP CUT COSTS
ASTO 500 may help to keep engine components clean, thereby extending bearing life and reducing maintenance costs. It is a 5-cSt, hindered-ester synthetic oil with carefully selected and balanced additives, and has been
developed to meet the MIL-PRF-23699 (STD) specification. ASTO 500 has good corrosion and oxidation stability, which can help to protect engines and cut costs.
REDUCED COKE FORMATION, LOWER MAINTENANCE COSTS
Oil that cannot cope with high engine operating temperatures may form coke. If not removed during engine overhauls, that coke can block oil ducts and cause engine bearing failures because of oil starvation. ASTO 500 may help to reduce maintenance time and costs by resisting coke formation, thereby keeping engine components clean. It produces n 6 to 27% less deposition in high-temperature bearing tests1, when compared with a leading standard grade MIL-PRF-23699 oil.
BETTER WEAR PROTECTION FOR LONGER ENGINE LIFE
Wear under conditions of marginal lubrication can lead to increased maintenance costs. ASTO 500 helps to reduce maintenance costs by offering good load-carrying capacity, as demonstrated by Ryder gear test results.2
SPECIFICATIONS AND APPROVALS
ASTO 500 is fully approved to:
- n MIL-PRF-23699G standard grade
- n SAE AS 5780B SPC
- n DEF STAN 91-101 Grade OX-27
ASTO 500 is approved by almost all engine and accessory manufacturers, including the following:
CHANGING OIL WITH CONFIDENCE
You can switch oils to take advantage of ASTO 500’s benefits with the confidence that it is compatible with other MIL-PRF-23699 standard grade oils. As there is little difference in elastomer seal swelling rates, ASTO 500 can replace other MIL-PRF-23699 oils without any issues. If you operate modern gas-turbine engines, you may be able to reduce your operating costs further by upgrading to ASTO 560.
A COMPREHENSIVE RANGE
Whatever you fly, we can provide a full range of AeroShell oils, greases and fluids for your aircraft, including:
- n AeroShell Grease 33, the universal airframe grease used as a first-fill product by both Boeing and Airbus
- n AeroShell Fluid 41 “super-clean”, mineral hydraulic oil.
2Ryder gear tests measure the load required to produce a wear scar of a certain diameter compared with the load required to create the same wear scar diameter when using a reference oil.
