Lubricating oil W80

piston engine

Product overview
AeroShell Oil W80 is an ashless dispersant piston engine oil designed to minimise wear during cold starts and to provide reliable lubrication at lower ambient temperatures (-17°C to 21°C / 1°F to 69°F). It is intended for use in certified four-stroke reciprocating piston aircraft engines, including fuel-injected and turbocharged variants.

Features and benefits

• Suitable for colder climates — Lower viscosity ensures reliable lubrication and oil flow in cooler ambient conditions (-17°C to 21°C / 1°F to 69°F).
• Designed to keep particles separated — Ashless dispersant additive technology helps prevent deposit build-up for cleaner combustion chambers and more consistent engine performance.

Applications
AeroShell W Oils are available in three viscosity grades: AeroShell Oil W80, AeroShell Oil W100 and AeroShell Oil W120. The suffix for each grade corresponds to the oil viscosity at 210°F measured in Saybolt Universal Seconds. AeroShell W Oils are intended for four-stroke cycle certified reciprocating piston engines; this includes turbocharged and fuel-injected engines. They are not recommended for automotive engines. Radial engine operators typically use AeroShell Oil W120 in warm conditions, while AeroShell Oil W100 or AeroShell Oil W 15W-50 are preferred in cooler ambient temperatures. For many Lycoming and Continental flat engines, AeroShell Oil W100 or AeroShell Oil W 15W-50 are common choices; during colder periods AeroShell Oil W80 can be used in place of AeroShell Oil W100.

Health, Safety and Environment
Health and safety guidance is provided in the product Safety Data Sheet (SDS).

• Protect the environment — Dispose of used lubricant at an authorised collection point. Do not discharge into drains, soil or water.
