AeroShell Aviation Oil W100 Plus — 6×1 qt Case, Single‑Grade Piston Oil with Anti‑Wear & Corrosion Protection

Designed from AeroShell’s proven aviation lubricants technology, W100 Plus brings enhanced antiwear chemistry and dispersant additives into a single‑grade viscosity oil favored for warm operating conditions. It blends high‑viscosity‑index base stocks with non‑ash polymeric additives to help keep combustion chambers and spark plugs cleaner while providing rust and corrosion resistance during short‑ and long‑term storage. This product is sold as a 6×1 quart case and ships to the lower 48 US states only.

How does AeroShell W100 Plus improve protection at engine start and high temperatures?

AeroShell W100 Plus includes advanced antiwear ingredients that form a protective film on metal surfaces, reducing metal‑to‑metal contact at startup and under heavy loads. The single‑grade nature gives stable viscosity in hot weather, helping the oil retain lubricating film strength when temperatures rise.

• Contains antiwear additives that reduce start‑up scuffing.
• High viscosity‑index base oils maintain thickness at elevated temperatures.
• Single‑grade formula resists thinning during summer operations.

Will W100 Plus keep my combustion chambers and plugs cleaner?

Yes — the ashless dispersant package was developed to minimize metallic ash deposits that accumulate in combustion areas and on spark plugs. By reducing deposit formation, the oil helps preserve combustion efficiency and eases maintenance intervals related to fouled plugs or chambers.

• Polymeric, non‑ash dispersants limit harmful metallic ash buildup.
• Formulation helps prevent heavy carbon and lead residue on plugs.
• Promotes cleaner combustion surfaces compared with conventional single‑grade oils.

Is this oil compatible with Lycoming engines and other approved piston oils?

AeroShell W100 Plus contains the LW‑16702 additive proportioning required by certain Lycoming models and meets the referenced Lycoming guidance and FAA directive compliance. It is compatible with other approved aircraft piston oils, though mixing with other products may reduce some of the W100 Plus performance benefits.

• Includes Lycoming additive in correct proportions for compatibility.
• Meets applicable FAA airworthiness directive requirements.
• Compatible with other approved piston oils; for best results avoid mixing.

How does W100 Plus protect engines during storage and periods of non‑use?

The formulation provides enhanced rust and corrosion resistance for internal components when an aircraft sits idle for moderate storage intervals. For prolonged storage, AeroShell recommends or provides alternative preservation fluids better suited to very long layovers.

• Improved rust inhibitors help protect metal parts during short‑term non‑use.
• Lubricant film resists moisture‑triggered corrosion in common storage conditions.
• For extended storage, consider specialized storage fluids such as AeroShell Fluid 2F.

Who this is for: AeroShell Oil W100 Plus is aimed at private and commercial piston‑engine aircraft owners and maintenance professionals who prefer a single‑grade oil with boosted antiwear and dispersant performance—especially operators in warmer climates or those who want an oil that reduces combustion deposits and provides good short‑term storage protection. Offered as a 6×1 quart case, it suits flight schools, maintenance shops, and owners who perform regular oil changes and value compatibility with Lycoming engines. Ships to the lower 48 US states only.
