Shell laboratories, both in Europe and the USA, have worked closely with major engine manufacturers to produce the world's first specifically developed engine oil, AeroShell Oil Sport Plus 4, for light sport and very light/ultralight aircraft 4-stroke engines.
Old Blends vs. New Aviation Needs
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.
Why is AeroShell Oil Sport Plus 4 an important new lubricant?
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 ideal; as it 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.
So when you change your oil to new AeroShell Oil Sport Plus 4, you are not only helping to remove dirt from your engine, you are also replenishing the additives designed to protect your engine during normal operation.
AeroShell Oil Sport Plus 4 Additive technology is perfectly suited to the requirements of integrated gearbox and overload clutches (ROTAX® 912 & 914 Series). Formulated with excellent elastomer compatibility to help protect hoses and seals. This oil 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.
