Lubricating oil W80 Plus

piston engine

Product overview
AeroShell Oil W80 Plus is a single-grade, ashless dispersant oil formulated for aviation piston engines. It combines the anti-wear and anti-corrosion chemistry of AeroShell multigrades with a single-grade viscosity to provide reliable protection during operation and periods of inactivity. The formulation supports cold-start performance and helps protect valve train components.

Features and benefits

• Advanced additive package — Protects against rust, corrosion and wear to support longer component life.
• Lycoming anti-wear protection — Contains the Lycoming LW 16702 anti-wear additive to safeguard camshafts and lifters.
• Ashless dispersant technology — Keeps contaminants and combustion by-products suspended to reduce deposit formation and maintain engine cleanliness.
• Improved load-carrying capacity — Reduces metal-to-metal contact under load for enhanced component durability.
• Cold-climate performance — Lower viscosity for reliable lubrication and oil flow in colder ambient temperatures (-17°C to 21°C / 1°F to 69°F).

Applications
AeroShell Oil W80 Plus is intended for piston-engine aircraft where a single-grade ashless dispersant oil is specified or preferred. The additives provide improved rust and wear protection compared with conventional single grades, helping to keep camshafts and lifters coated during idle periods and reducing the risk of premature damage, which supports operators in achieving recommended TBO intervals.

Health, Safety and Environment

• When used as recommended and with appropriate hygiene, the product is unlikely to present significant health hazards.
• Avoid skin contact; use impervious gloves when handling used oil and wash exposed skin promptly with soap and water.
• Protect the environment: collect and dispose of used lubricant at authorised facilities; do not release into drains, soil or water.
