AeroShell Oil W100 Plus quart case - Single Grade Engine Oil

In this review of AeroShell Oil W100 Plus the bottom line is simple: this single grade aviation oil is for pilots and maintenance crews who want dependable rust protection and improved start-up wear control in piston engines. Our review finds it especially useful for aircraft stored for periods and for Lycoming-powered engines because it contains the required LW-16702 additive and meets the FAA airworthiness directive, so buyers get a ready-to-use oil that reduces the need for additional supplements.

Key Features

• Rust and corrosion protection: Provides superior protection to engine parts that may be susceptible to extreme rusting when an aircraft sits unused.
• Lycoming compatibility: Contains the LW-16702 additive in the correct proportion so it meets Lycoming requirements without supplemental additives.
• Improved anti-wear: Advanced antiwear chemistry helps protect components particularly at engine start-up, where wear is most likely.
• Deposit control: Ashless dispersant formulation reduces harmful combustion chamber and spark plug deposits for cleaner operation.
• High viscosity index bases: Base oils maintain viscosity under shear, helping protect engine components during severe operating stresses.
• Interchangeable with approved oils: Compatible with other approved aircraft piston engine oils while retaining most performance benefits when used alone.

Who It's For

AeroShell Oil W100 Plus is aimed at general aviation owners and maintenance shops that operate four-cycle piston aircraft, especially those with Lycoming engines or aircraft that face occasional prolonged storage. It is a good choice for flyers who prefer a single grade oil with strong summer heat resistance and rust prevention.

Pilots who need multigrade performance across a wide temperature range, or those requiring specialized fluids for extended storage beyond typical lay-up periods, should consider alternate products specified for long-term preservation or multigrade operation. For prolonged non-use, AeroShell recommends using AeroShell Fluid 2F instead.

Pros & Cons

Pros

• Contains the Lycoming LW-16702 additive, eliminating separate additive requirements for compliant engines.
• Strong rust and corrosion protection that helps preserve engine internals during periods of non-use.
• Ashless dispersant formulation promotes engine cleanness by reducing combustion deposits.
• High viscosity index base oils help maintain protective film under shear and heat.

Cons

• As a single grade oil, it may not offer the same cold-start benefits as multigrade oils in very low temperatures.
• Mixing with other oils reduces some of the product's superior performance features.

Our Verdict

AeroShell Oil W100 Plus is a pragmatic choice for owners of Lycoming and other approved piston engines who want single grade reliability with built-in LW-16702 additive and strong rust protection. It represents good value for aircraft that need a ready-to-use oil that limits deposit formation and protects during storage, though operators in extreme cold or needing multigrade behavior should evaluate alternatives.

Frequently Asked Questions

Is this oil approved for Lycoming engines?
Yes, AeroShell W100 Plus contains the LW-16702 additive in the correct proportions and meets Lycoming requirements.

Can I mix this with other aviation oils?
It is compatible with other approved aircraft piston engine oils, but mixing will reduce some of W100 Plus's superior performance features.

Can I use this for long-term storage protection?
It provides enhanced rust and corrosion protection for periods out of use, but for prolonged non-use AeroShell recommends using AeroShell Fluid 2F.
