Aeroshell and Silmid

Silmid have been a partner of Shell Aviation for almost 40 years. We are now recognised as their leading European distributor. This allows us to provide the full portfolio of the AeroShell branded products to customers.

From aircraft piston engine oils, jet oils, greases or hydraulic fluids, AeroShell is one of the most comprehensive and proven ranges of aviation lubricant products. Combine this with what is among the best technical support in the industry. The AeroShell range has been trusted for generations and used extensively in the aviation lubricants market worldwide. 

We sell a range of Aeroshell products including:


Turbine Engine Oils

Turbine engine oils (TEO) are designed to give you high load-carrying capacities for extended bearing life under conditions of marginal lubrication, which can help to reduce maintenance costs.

Turbine engine oils are known for their outstanding quality and product performance. Ascender set a new performance benchmark for the latest generation turbine engines, delivering the balance between low coking and elastomer compatibility. 

Turbine Oil 560 has offered proven performance for more than 25 years.

Hydraulic Specialist Fluids

Particulates in hydraulic fluids can cause system failures through valve sticking, wear and blockages in nozzles and tubes. Particulates are especially challenging for modern hydraulic systems that operate at high pressures and have components with tight tolerances.

Shell offers a wide range of hydraulic fluids designed to protect aircraft hydraulic systems. These products include fire-resistance and super-clean fluids for enhanced reliability, extreme-pressure fluids designed to protect landing gear struts from wear, and specialist preserving fluids for hydraulic system components in storage. Speciality fluid offerings include high-quality preservative, calibration, de-icing and avionic cooling fluids as well as lubricating and gearbox oils

Piston Engine Oils

Engine and oil technologies are constantly being reinvented. For example, the recently developed diesel (compression-ignition) aircraft engines are becoming popular for good reasons. They can be up to 30% more fuel efficient than spark-ignition engines and run on widely available, relatively low cost jet fuel.

A piston engine oil’s function inside a piston engine is to reduce friction between moving parts, provide necessary cooling to internal areas and cushion moving parts against shock and help seal piston rings to cylinder walls. PEO's are also designed to protect highly finished internal parts of the engine from rust and corrosion and keep interior of engine clean and free of dirtsludge and other harmful contaminants.


Do you spend too much time and money on maintenance or manage a large grease inventory? Are you concerned about the risks of product misapplication? The grease portfolio contains products designed to help reduce costs and improve safety by simplifying maintenance.

These multipurpose greases satisfy a wide range of performance specifications, which means you need fewer grease types. The result is simpler maintenance procedures, smaller inventories and reduced risk of product misapplication
