AeroShell Oil Sport Plus 4 is the world’s first oil specifically developed for light sport, very light and ultralight four-stroke engine aircraft. It is multigrade for use in any climate and combines synthetic and high-quality mineral oil with advanced additive technologies for excellent performance, wear and corrosion protection, and cleanliness with leaded and unleaded fuels.
Historically, light sport aircraft operators had to rely on motorcycle oils with formulations that could vary geographically and be changed without notifying the aviation community. Some of the changes that are good for motorbike engines may not be good for aviation engines, and motorbike oils may not keep engines clean with leaded aviation fuels.
With AeroShell Oil Sport Plus 4, aviators have a consistent worldwide formulation that cannot be changed without notice. It is designed to cope with the high shear stresses associated with integrated gearboxes and overload clutches, and has detergents that help to keep critical areas, such as pistons and cylinders, clean.
AeroShell Oil Sport Plus 4 has been improved. The new formulation is built on more than 11 years of close co-operation, including three years of development and testing of the new formulation by Shell and BRP-Rotax’s research scientists.
The new formulation is the first aviation oil tested and approved by BRP-Rotax. It offers improved anti-wear protection compared with the previous generation oil, and provides enhanced protection and lubricity for the smooth movement of clutch and gearbox components.
AeroShell Oil Sport Plus 4 offers all-year, all-climate protection through its multigrade formulation has a consistent, worldwide formulation that cannot be changed without consultation with major engine manufacturers is designed for engines with integrated gearboxes and overload clutches (for example, BRP-Rotax 912 and 914 Series engines) through advanced additives and synthetic-technology base oils with excellent shear stability works with unleaded aviation and road fuels, and avgas 100LL.
It helps to prevent the sludge and varnish associated with leaded fuels, thanks to its synthetic‑technology base oils and strong detergents1 helps to meet TBO (time-before-overhaul) requirements through advanced additives that protect components from wear and corrosion helps to maximise lubrication effectiveness through anti-foaming additives, which are particularly important for engines with integrated gearboxes.
AeroShell Oil Sport Plus 4 meets or exceeds the highest international specifications:
Do not use AeroShell Oil Sport Plus 4 in engines that are designed to use ashless dispersant or ashless non-dispersant aviation piston engine oil. This includes air-cooled Teledyne Continental Motors, Textron Lycoming and Jabiru engines. Please consult your operator’s handbook or manual to confirm the correct lubricant specification before use.
