AeroShell Sport Plus 4 10W-40 Engine Oil
AeroShell Oil Sport Plus 4 is a semisynthetic SAE 10W-40 multigrade oil developed with ROTAX for four-stroke light-sport, Very Light, and Ultra Light aviation piston engines. It is formulated for engines of original automotive design that use integrated gearboxes, wet clutches, and operating systems that are not compatible with traditional ashless dispersant aviation piston-engine oils.
Its blend of high-quality hydrocarbon base stocks and synthetic technology provides cold-start flow, thermal stability, resistance to high shear stress, and anti-foaming performance. The oil also contains anti-rust and anti-wear additives that protect highly stressed engine, gearbox, and clutch components.
AeroShell Sport Plus 4 can be used in any climate and is suitable for engines operating on unleaded gasoline or Avgas 100LL. Its additive and solvent system helps manage lead by-products that can accumulate when leaded aviation fuel is used.
