AeroShell Diesel Ultra Aircraft Engine Oil 1 Quart
Advanced lubrication technology for modern aviation diesel engines. AeroShell Diesel Ultra is a premium SAE 5W-30 multigrade piston engine oil based on synthetic technology, specifically developed for compression-ignition aircraft engines operating on Jet A or Jet A-1 fuel.
Its formulation addresses the unique demands of aviation diesel engines, including high mechanical loads, turbocharged operation and the combustion characteristics of jet fuel.
Developed for Jet A and Jet A-1 Aircraft Engines
Modern aviation diesel engines differ significantly from conventional spark-ignition aircraft piston engines.
AeroShell Diesel Ultra has been specifically developed to meet the lubrication requirements of compression-ignition engines burning Jet A or Jet A-1.
Its performance is optimised for this engine and fuel combination, supporting dependable lubrication during demanding aviation operations.
SAE 5W-30 Synthetic Technology
AeroShell Diesel Ultra uses synthetic-based multigrade technology with an SAE 5W-30 viscosity classification.
The formulation supports oil circulation at lower temperatures while providing effective lubrication during normal engine operation.
Its multigrade characteristics make it suitable for the specified operating conditions of approved aviation diesel engines.
Reliable Protection Against Wear
The oil has been developed using extensive field experience and endurance testing with aviation diesel engine manufacturers.
Its additive technology helps protect highly loaded engine components by forming a protective layer on metal surfaces.
This contributes to resistance against scuffing and wear under demanding mechanical loads.
Enhanced Engine Cleanliness
Combustion of Jet A and Jet A-1 fuel can produce contaminants that place particular demands on engine lubricants.
AeroShell Diesel Ultra offers high dispersancy to help keep contaminants suspended and maintain engine cleanliness.
This supports reliable operation and helps control unwanted deposits.
Protection Against Sulphur-Related Acids
Sulphur present in aviation fuel can contribute to the formation of acidic combustion by-products.
AeroShell Diesel Ultra contains additives designed to neutralise acid build-up associated with sulphur in fuel.
This provides additional protection for engine components and supports long-term engine durability.
Suitable for Approved Turbocharged Diesel Engines
AeroShell Diesel Ultra is designed for modern aviation diesel engines, including approved turbocharged applications.
Shell lists the following engine manufacturers and models in its specifications and approvals:
- Austro Engine AE300
- SMA SR305-230E
- Thielert/Centurion 1.7
- Thielert/Centurion 2.0
Always verify the applicable engine model and current manufacturer instructions before use.
Not for Spark-Ignition Aircraft Engines
AeroShell Diesel Ultra must not be used in spark-ignition or Avgas-powered aircraft engines.
It is a specialised lubricant for approved compression-ignition aviation engines and must not be substituted for conventional AeroShell piston engine oils.
