AeroShell SHAEW155-12 15W-50 Aviation Oil — 1 Quart, 12 Pack | Premium Piston Engine Lubricant

AeroShell SHAEW155-12 is a premium semi-synthetic aviation oil crafted for piston engines across a wide range of operating conditions. This ashless dispersant formulation blends a high quality mineral oil with select synthetic hydrocarbons and a thoughtful additive package to help maintain engine cleanliness and steady performance.

The formulation emphasizes cleanliness and protection. The non ash forming polymeric additives promote cleaner engine surfaces, while a high viscosity index base supports stable lubrication under load and across temperature swings. The result is a lubricant that can contribute to smoother starts, steadier oil film, and reliable operation in routine flights.

Key advantages

• Ashless, polymeric additives support cleanliness and deposit control
• High viscosity index semi synthetic base oils resist viscosity changes under load
• Potential oil consumption reduction up to 50 percent and fuel use down to 5 percent versus straight grade oils
• All season compatibility with other approved piston engine oils
• Enhanced protection in extreme ambient temperatures for consistent operation

Lycoming operators may appreciate the tailored approach of the SHAEW155-12 formulation. The blend includes the Lycoming LW 16702 anti wear package, designed to support load carrying and protect camshafts and lifters without extra additives. The oil is designed to perform well with commonly recommended piston engine oils, offering flexibility in maintenance planning.

Real world use and compatibility

Whether you fly in hot climates or cool mornings, this oil is designed to maintain film strength and dispersancy. It is suitable for engines requiring robust wear protection and is compatible with other approved oils, simplifying topping off and mixed fleet use.

• Lycoming LW 16702 anti wear package is incorporated to support critical wear surfaces
