Application:

AeroShell Oil W 80 is an SAE 40 grade mineral ashless dispersant oil developed for use in certified four-stroke cycle (reciprocating) aircraft piston engines. It is part of the AeroShell W Oil series—formulated without metallic ash additives to reduce deposit formation and spark plug fouling.

Performance Features & Benefits:

  • Engine Cleanliness: Helps prevent sludge build-up and combustion chamber deposits.
  • Reduced Oil Consumption: Minimizes oil loss and supports extended engine performance.
  • Wear Protection: Shields highly stressed components from scuffing and premature wear.
  • Ashless Dispersant System: Leaves no metallic ash—protecting plugs and combustion efficiency.
  • Supports TBO Goals: Helps engines achieve full Time Between Overhaul with proper maintenance.

Main Application Areas:

  • Certified four-stroke (four-cycle) reciprocating piston aircraft engines
  • Lycoming and Continental engines (cold to moderate climates)
  • Turbocharged and fuel-injected aircraft engines where ashless oils are specified
  • Potential use in engine break-in when permitted by engine manufacturer
