Phillips 66 Type M 20W-50 is the trusted choice for aviation professionals seeking reliable, detergent-free lubrication for specialized engine needs.
Phillips 66 Type M 20W-50 Aviation Oil is a high-quality, mineral-based, non-dispersant engine oil specifically formulated for use in aircraft piston engines where ashless dispersant (AD) oils are not recommended. Ideal for vintage aircraft, break-in periods, or engines designed to run on straight mineral oil, Type M delivers dependable lubrication and excellent wear protection without the use of detergent additives.
This SAE 20W-50 multigrade formulation ensures easier cold starts and consistent oil flow while maintaining strong film strength at elevated operating temperatures. It helps condition seals and gaskets and is often used during engine break-in to promote proper ring seating and reduce oil consumption.
Key Features:
✅ Straight mineral (non-AD) oil for specific aviation engine applications
✅ SAE 20W-50 multigrade formulation for all-season performance
✅ Recommended for engine break-in and vintage aircraft use
✅ Provides excellent wear protection and thermal stability
✅ Helps prevent rust and corrosion during storage or downtime
✅ Meets SAE J1966 standards for aviation piston engines
