Application:

AeroShell Oil W 15W-50 is a semi-synthetic multigrade lubricating oil for use in certified four-stroke cycle aircraft piston engines. It combines high-quality mineral oil with synthetic hydrocarbon base stocks and ashless dispersant additives to provide optimal protection across a wide range of operating conditions.

Performance Features & Benefits:

  • Superior Corrosion Protection: Guards internal engine components against rust, especially in high humidity or infrequent-use conditions.
  • Outstanding Wear Resistance: Protects camshafts, lifters, and other critical parts during start-up and operation.
  • Enhanced Engine Cleanliness: Reduces sludge and varnish deposits in high-temperature zones.
  • Fuel and Oil Efficiency: Cuts oil consumption by up to 50% and fuel use by up to 5% compared to single-grade oils.
  • All-Season Use: Multigrade formulation eliminates the need for seasonal oil changes.
  • Wide Compatibility: Fully compatible with other approved piston engine oils.
  • Improved Flow Characteristics: Offers better cold start lubrication and high-temp stability.

Main Application Areas:

  • Certified four-stroke cycle aircraft piston engines (including Textron Lycoming, Continental, Pratt & Whitney)
  • Engines operated in variable temperature environments
  • Aircraft with high rust-prevention requirements or limited usage periods
