To mark the anniversary of the Rotax engine family, BRP has organised the Rotax Fly-In, a celebratory event which takes place from 5 to 7 June 2014 at Weisse Moewe Wels Flying Club, Wels, in Upper Austria. The event brings together customers, personnel and suppliers and offers an opportunity to visit the BRP-Powertrain factory in nearby Gunskirchen.

Guests can see where Rotax engines are produced, meet with the engineers and participate in a variety of training sessions run by experienced service partners. Shell Aviation is pleased to be able to mark the occasion by making a presentation about the long-term collaboration between the two companies.

A strong and shared heritage of innovation

The relationship between Shell Aviation and BRP started in 2003 Shell worked with Rotax to create specially formulated oils for light sport aero engines. Shell developed a set of experimental oils which BRP then tested in the Rotax engine to fulfil the customer’s requirements.

The result of this co-engineering process was ASO Sport Plus 4, a new Shell lubricant specifically created for light sport aero engines which was included in the wider Shell Aviation portfolio and made available to other customers. A true success born out of technological collaboration. Co-engineering allows Shell Aviation and BRP to make use of each other’s lab and field facilities, personnel and research, ensuring that the products meet the most stringent industry criteria and combine the best of cutting-edge technology and innovation.

Mark Wakem, Project Leader, Motorsport and Aviation Piston Engine Oil Development, who has been leading the project from the very beginning, said:“By collaborating with BRP, Shell Aviation developed an oil specifically for light sport and ultralight aircraft 4-stroke engines using innovative technology. We are proud to have created a successful technical cooperation with BRP and their Rotax aircraft engines and we will continue to work together on future oil and hardware developments.”

About AeroShell Oil Sport PLUS 4

Aviation Oil for Light Sport Four Stroke Engines

Historically, operators of these types of engines have had to rely on commercially available motorcycle oils. This may lead to issues, such as formulation changes that follow the needs of the motorcycle market. These formulation changes can be made without notification to the aviation community, because motorcycle oils are not required to meet the same specification as aviation oils. Motorcycle oils also tend to have limited ability when dealing with leaded fuels used in aviation – Avgas 100LL.

Because most 4-stroke engines now come with integrated gearbox and overload clutch systems, the same oil is in contact with all the moving parts, so it must be capable of coping with the engine, overload clutch and gearbox simultaneously.

AeroShell Oil Sport Plus 4 is extremely resistant to the immense sheer forces that occur in areas of high-pressure contact such as high-speed gearboxes, valve trains, bearings, pistons and liners. This is where the blend of base oil and additives is most crucial.

AeroShell Oil Sport Plus 4 is made up of a blend incorporating synthetic technology and high performance additives to help provide long lasting protection.

In addition, detergents in the oil are designed to keep important areas, such as the pistons and cylinders, clear of carbon based particles that tend to adhere to these surfaces.


  • SAE 10W-40 Multigrade oil designed to be used in any climate, anywhere in the world.
  • Additive technology, which perfectly suits the requirements of integrated gearbox and overload clutches (ROTAX® 912 & 914 Series).
  • High thermal stability for longer-lasting and safer lubrication.
  • High evaporative stability to lower engine oil consumption.
  • Better cold flow characteristics for easier starts and quicker protection.[1]
  • Advanced anti–corrosion and anti-wear additive package. These additives work as a protective barrier to help prevent critical parts from being slowly degraded by corrosion or wear, especially when an aircraft is used infrequently. This protection is crucial for critical internal parts, especially during engine start, reducing the likelihood of premature damage and helping engines reach TBO.
  • Powerful anti-oxidancy action to help protect and clean parts for longer periods of time.
  • Strong dispersants to help prevent build up of sludge and varnish.
  • Specially selected base oils incorporating synthetic technology to help prevent sludge problems when operating with leaded fuels. This also provides excellent sheer stability.
  • Anti-foaming additives designed to maximise lubrication effectiveness. This is extremely important for those engines which operate with an integrated gearbox.
  • Excellent elastomer compatibility to help protect hoses and seals.
  • Special additives to neutralise acid build-up.
  • Can be used with both unleaded fuels and Avgas 100LL. Please refer to Operators Handbook/Manual for the correct oil drain interval when operating on different fuels.


Meets or Exceeds Highest International Specifications:

  • API SL
  • VW 502 00
  • Fully Approved – All ROTAX® 912 &914 Series engines, Rotax Service Instruction SI-912-016/SI-914-019; selection of suitable operating fluids for ROTAX® engine type 912 & 914 (Series).
  • AeroShell Oil Sport Plus 4 is the world’s first truly specific aviation engine oil developed for light sport and ultralight aircraft engines. This is an oil which is available throughout the world, backed by the proven history and dependability of the AeroShell family, and trusted by the majority of General Aviation pilots and engineers alike.
