Phillips 66 Type M Aviation Oil is an ashless, non-dispersant, multi-grade (20W-50) mineral-based engine oil. It is primarily used as a break-in oil for newly overhauled or reconditioned aircraft piston engines to help piston rings seat properly while preventing cylinder glazing.
Key Features
- Non-Dispersant Mineral Oil: Contains no dispersant additives, allowing metal and combustion particles to drop out rather than stay suspended, which aids the break-in process. [
- Multi-Grade Performance (20W-50): Flows easily during cold weather starts yet maintains strong film protection under high operating temperatures and loads.
- Short-Term Use: Typically run for fewer than 25 hours of engine operation until the break-in phase is complete.
- Specifications: Meets SAE Standard J1966 requirements.
