Shell Turbine Oil & Aviation Lubricants

The Mobil DTE™  Oil Named Series of lubricants are premium performance circulating lubricants designed for applications including steam and hydro turbine sets and other systems where long lubricant service life is required. Mobil DTE Oil Named Series lubricants are formulated from highly refined base stocks and an additive system which provide an extremely high level of chemical and thermal stability, rapid and complete separation from water and a high resistance to emulsification. They provide excellent protection against rust and corrosion, including resistance to salt water, and good antiwear properties. They have a high viscosity index which ensures minimum variation of film thickness with temperature and minimum power loss during the warm up period. These grades have excellent air release properties which allow entrained air to separate, thus avoiding pump cavitation and erratic operation.

Mobil DTE Oil Named are the lubricants of choice for many users because of their reputation for long life, excellent equipment protection and outstanding versatility in the wide variety of industrial applications. DTE Oil Named lubricants are used widely in steam turbines and hydroturbines with splash, bath and ring-oiling arrangements, and all other continuous circulation methods involving pumps, valves and ancillary equipment. This product series is recommended for continous service in the lubrication of plain and rolling bearings and parallel shaft gearing. They have also been used successfully in rotary air compressor applications and reciprocating natural gas compressors as well as vacuum pumps. Their reputation is based on many decades of successful service and satisfied users.

Mobil SHC™ 800 Series turbine oils are designed specifically to meet the needs of the most severe industrial gas turbine applications with a nominal 10,000 hour TOST life. They are recommended for the lubrication of land-based gas turbines, particularly units under 3,000 hp used as standby power units, and in some types of total energy and combined cycle (gas/steam) systems. This product family is formulated with synthesized hydrocarbons and a unique additive system. This formula provides outstanding low temperature fluidity and exceptional resistance to degradation at high temperatures. Mobil SHC 800 Series lubricants also provide excellent antiwear properties as well as protection against rust and corrosion plus good air release performance and resistance to foaming.

These characteristics help to provide superior resistance to thermal/oxidative degradation during the heat soaking period after shutdown and permit rapid oil circulation at low temperatures during start-up. Degradation resistance is a key attribute in avoiding harmful deposits that can interfere with lubrication supply to the bearings or foul critical servo-valves. This is a particular issue when gas turbines are running in cycling mode and experience multiple thermal stress cycles. Since low temperature fluidity and high viscosity index are inherent characteristics of the fluids, they resist changes in service as a result of mechanical shearing or repeated cycling from low to high temperatures. Mobil SHC 800 Series oils are fully compatible with mineral oils, but admixture will detract from their superior performance properties.

Mobil DTE™ 732 M is next generation high performance turbine oil designed for use in Mitsubishi Heavy Industry (MHI) non-geared Single Shaft Heavy Duty Gas & Steam Turbines and Multi Shaft Gas Turbines. This product meets MHI's requirements for long life – high temperature turbine applications, MS04-MA-CL005, through high quality base oils and additive system designed to provide long oil life. Mobil DTE 732 M also meets the requirements of MS04-MA-CL001 and CL002.

• Remove to fresh air. Do not attempt to rescue the victim
  unless proper respiratory protection is worn. If the victim has
  difficulty breathing or tightness of the chest, is dizzy, vomiting,
  or unresponsive, give 100% oxygen with rescue breathing or
  CPR as required and transport to the nearest medical facility.
• Remove contaminated clothing. Immediately flush skin with
  large amounts of water for at least 15 minutes, and follow by
  washing with soap and water if available. If redness, swelling,
  pain and/or blisters occur, transport to the nearest medical
  facility for additional treatment.
• Flush eye with copious quantities of water.
  If persistent irritation occurs, obtain medical attention.
• If swallowed, do not induce vomiting: transport to nearest
  medical facility for additional treatment. If vomiting occurs
  spontaneously, keep head below hips to prevent aspiration.
  If any of the following delayed signs and symptoms appear
  within the next 6 hours, transport to the nearest medical
  facility: fever greater than 101° F (38.3°C), shortness of
  breath, chest congestion or continued coughing or wheezing
• If material enters lungs, signs and symptoms may include
  coughing, choking, wheezing, difficulty in breathing, chest
  congestion, shortness of breath, and/or fever.
  The onset of respiratory symptoms may be delayed for
  several hours after exposure.
  Skin irritation signs and symptoms may include a burning
  sensation, redness, swelling, and/or blisters.
  Defatting dermatitis signs and symptoms may include a
  burning sensation and/or a dried/cracked appearance.
  Ingestion may result in nausea, vomiting and/or diarrhoea.
• When administering first aid, ensure that you are wearing the
  appropriate personal protective equipment according to the
  incident, injury and surroundings.
• High pressure injection injuries require prompt surgical
  intervention an d possibly steroid therapy, to minimise tissue
  damage and loss of function.
  Because entry wounds are small and do not reflect the
  seriousness of the underlying damage, surgical exploration to
  determine the extent of involvement may be necessary. Local
  anaesthetics or hot soaks should be avoided because they
  can contribute to swelling, vasospasm and ischaemia. Prompt
  surgical decompression, debridement and evacuation of
  foreign material should be performed under general
  anaesthetics, and wide exploration is essential.

Many modern jet engines require fit-for-purpose lubricant products that can handle high speeds, temperatures, and related stresses without breaking down or forming deposits. As such, lubricant performance is a significant contributor to extended engine life, longer maintenance cycles, and fewer commercial disruptions.

Since the birth of modern aviation, Shell Aviation has been providing quality fuels, lubricants and associated services to the aviation community. For more than 100 years, Shell has played a crucial role in many landmark events in the aviation industry – including helping Sir Frank Whittle develop the jet engine. Today, Shell Aviation offers a wide range of lubricating oil products, including the latest generation of synthetic oils capable of taking turbine engine performance to new heights.

AeroShell Turbine Oil 560 (ASTO 560) is the third generation 5-centistoke synthetic hindered ester lubricating oil, designed to provide commercially viable performance and benefits such as reduced coking and improved wear resistance for modern jet engines. Formulated to cope with demanding operating conditions, ASTO 560 has consistently delivered the right balance of performance and cost efficiency to the global aviation industry over the past 25 years.

ASTO 560 is developed based on a deep understanding of commercial aviation requirements. The result is a versatile lubricating oil proven to deliver cleaner engines, more reliable operational performance and longer maintenance cycles.

• Reduced coke formation: Coke formation and shedding can be disruptive to airline operations. Reduced coke deposits can lower maintenance costs and increase on-wing life.
• Fully compatible with other approved oils: No engine problems such as coke shedding and oil filters blocking is experienced when changing from one approved oil to ASTO 560, in accordance with the procedure outlined in the relevant engine service bulletin.
• No adverse effect on elastomer seals: ASTO 560’s full compatibility with all elastomer seal materials reduces the possibility of oil leaks, which could lead to expensive engine overhauls or even an in-flight engine shutdown.

Good oxidative and thermal stability: The use of ASTO 560 reduces the occurrence of oxidative and thermal degradation of the oil at high operating temperatures, which could result in high overhaul and maintenance costs due to:

• An increase in oil viscosity, which may result in the need for oil change
• An increase in acidity, which could lead to the corrosion of gears and bearings
• Sludge formation in the oil system, causing the blockage of oil jets and filters

Health and Safety:
AeroShell Turbine Oil 560 is unlikely to present any significant health or safety hazard when properly used in the recommended application, and good standards of industrial and personal hygiene are maintained.
