AeroShell Oil W80 Engine Oil

AeroShell Oil W80 SAE 40 Piston Engine Oil

AeroShell Oil W80 is a single-grade, mineral ashless dispersant oil developed for four-stroke certified reciprocating aircraft piston engines. It is suitable for fuel-injected and turbocharged engines where an SAE J1899 Grade 40 oil is specified.

Its non-metallic additive system provides dispersancy, oxidation stability, anti-foaming performance, and protection against scuffing and wear. The ashless dispersant formulation promotes engine cleanliness by helping keep sludge and suspended contaminants from accumulating in critical engine areas.

AeroShell Oil W80 is intended primarily for colder climates. It performs best in colder ambient air temperatures from approximately -17°C to 21°C (1°F to 69°F).

Frequently Asked Questions

What is AeroShell Oil W80 used for?

AeroShell Oil W80 is used in four-stroke certified reciprocating aircraft piston engines, including fuel-injected and turbocharged engines, where an SAE J1899 Grade 40 ashless dispersant oil is specified.

Is AeroShell Oil W80 an ashless dispersant oil or a straight mineral oil?

AeroShell Oil W80 is a mineral-based ashless dispersant oil. It contains non-metallic dispersant additives and should not be confused with AeroShell Oil 80, which is a straight mineral SAE 40 oil primarily associated with engine break-in.

Can AeroShell Oil W80 be used during engine break-in?

Break-in recommendations vary by engine manufacturer and overhaul facility. Some permit either ashless dispersant or straight mineral oil, while others specify straight mineral oil.

What is the difference between AeroShell Oil W80, W100, and W120?

The primary differences are viscosity grade and intended ambient conditions:

• AeroShell Oil W80 is SAE 40 and is intended for colder climates, approximately -17°C to 21°C.
• AeroShell Oil W100 is SAE 50 and is intended for moderate climates, approximately 16°C to 32°C.
• AeroShell Oil W120 is SAE 60 and is intended for warmer climates above approximately 26°C.

What is the difference between AeroShell Oil W80 and AeroShell Oil W80 Plus?

Both products are single-grade SAE 40 ashless dispersant oils intended for colder climates. AeroShell Oil W80 Plus contains additional anti-wear and anti-corrosion additives, including the Lycoming LW 16702 anti-wear additive. Standard AeroShell Oil W80 does not contain the same Plus additive system.
