AeroShell W100 Plus Aviation Piston Engine Oil — 6×1 qt Case, Lycoming-Approved Ashless Dispersant

AeroShell Oil W100 Plus is a single-grade aviation piston engine oil engineered to reduce combustion deposits while giving enhanced antiwear, rust and corrosion protection for general aviation engines.

AeroShell W100 Plus builds on decades of aviation lubricant technology to offer a single-grade oil that stays stable under heat, keeps engines cleaner, and includes the right Lycoming supplement so additional additives are typically unnecessary. Supplied here as a 6×1 quart case, this product is intended for aircraft owners and mechanics who want the convenience and protection of a proven ashless dispersant formulation. Note: shipping is available to the lower 48 United States only.

How does W100 Plus protect engines at start-up and during use?

The oil contains advanced antiwear components that form a protective film on metal surfaces, especially important at cold starts and during high-load periods. Its high-viscosity-index base stocks resist shear and maintain lubricating thickness, reducing metal-to-metal contact and wear.

• Includes antiwear additives optimized for start-up protection.
• High viscosity index base oils preserve film strength under stress.
• Meets Lycoming requirements and includes the LW-16702 additive.

Will W100 Plus keep my combustion chambers and spark plugs cleaner?

Yes — the formulation uses an ashless dispersant system designed to limit metallic ash deposits that can foul spark plugs and combustion chamber surfaces. By reducing deposit formation, it helps maintain ignition quality and combustion efficiency over time.

• Non-ash polymeric additive minimizes harmful combustion deposits.
• Dispersant chemistry suspends contaminants to reduce buildup.
• Promotes cleaner combustion components during routine operation.

Is W100 Plus compatible with other aircraft oils and engine types?

>AeroShell W100 Plus is formulated to be compatible with other approved aircraft piston engine oils, but mixing will dilute some of its specialized benefits. It already contains the Lycoming-specified additive package, so owners of Lycoming-equipped aircraft often do not need supplemental additives when using this oil.

• Compatible with other approved piston-engine oils if mixed.
• Includes Lycoming additive LW-16702 in proper proportions.
• Recommended for engines where single-grade performance is preferred.

How does W100 Plus resist corrosion and protect during storage?

The product adds robust rust and corrosion inhibitors to shield exposed engine parts, which is useful during periods of inactivity. For very long-term storage or extreme preservation, consider dedicated storage fluids, but W100 Plus offers superior short- to medium-term protection compared with many single-grade oils.

• Enhanced rust and corrosion inhibitors protect vulnerable components.
• Better protection than many comparable single-grade oils for intermittent use.
• For prolonged storage, consult storage-specific fluids like AeroShell Fluid 2F.

Who is this for: AeroShell Oil W100 Plus is aimed at private pilots, aircraft owners, and maintenance professionals who prefer a dependable single-grade oil that combines deposit control, antiwear protection, and rust inhibition. It’s particularly appropriate for Lycoming-engined aircraft and for operators who want reduced need for supplemental additives while maintaining cleaner combustion chambers. This 6×1 quart case is convenient for workshop stocking or routine maintenance schedules; remember delivery is limited to the contiguous United States.
