AeroShell Oil W 15W-50
Our most advanced aviation piston engine oil 鈥 a semi-synthetic blend of base oils integrating ashless dispersant technology and advanced non-metallic anti-wear and anti-rust additive system, providing fast-acting engine protection through oil drain intervals and in all seasons.
Features and benefits
Unbeatable steel corrosion resistance鹿
Provides excellent protection against rust and corrosion, keeping your aircraft in the sky and out of the workshop.
Outstanding Engine Cleanliness虏
Unsurpassed resistance to deposit formation, keeping engines cleaner for longer.
Temperature versatility
Maintains consistent performance across a broad temperature range, through all seasons.
Improved Wear Protection鲁
Incorporating the Lycoming LW 16702 anti-wear additive to provide enhanced wear protection for critical engine components like camshafts and lifters.
Exceptional cold flow performance鈦
Delivers faster cold startup protection, for longer component life.
Exceptional鈦 shear stability
Resists mechanical stress and maintains its viscosity, which helps to prevent oil thinning and ensures consistent lubrication under high-pressure conditions.

Applications
AeroShell Oil W 15W-50 is intended for use in certified four-stroke (four-cycle) aircraft piston engines. AeroShell Oil W 15W-50 is superior to single grade oils in almost every application. It offers easier starting, better lubrication after start-up, reduced wear, reduced corrosion and rusting, and improved cleanliness, with oil pressures and temperatures equal to that of single grade SAE 50 oils at fully warmed up conditions.
The anti-corrosion additive system is designed to prevent rust or corrosion in all types of aircraft piston engines. In comparative testing of camshaft rusting under high humidity conditions, AeroShell Oil W 15W-50 was almost entirely rust free while camshafts conditioned on other oils showed heavy rusting on some cam lobes and bearing surfaces.
These results indicate that AeroShell Oil W 15W-50 can provide maximum anticorrosion protection for aircraft piston engines, when combined with proper maintenance practices and proper operating conditions.
Because of the improved flow characteristics of AeroShell Oil W 15W-50, operators may observe slightly lower oil temperatures in some aircraft. On larger aircraft, the oil cooler flap will normally compensate for this change. However, in small aircraft, oil temperature could be reduced slightly. Operators should always check the oil temperature to ensure that they are in the range specified by the manufacturer. Most manufacturers recommend cruising oil temperatures between 82 to 93掳C (180 to 200掳F). Oil temperatures significantly below this range can result in excessive water and fuel contamination in the crankcase.
