Phillips 66 X/C 20W-50 Multiviscosity Mineral Aircraft Engine Oil
Phillips 66 Type M 20W-50 is generally recommended and used as a break-in oil for newly overhauled aircraft engines and is often used by engine overhaul and repair shops for the initial run-in of aircraft piston engines. Type M 20W-50 is designed for owners and pilots who want the performance of multi-viscosity, mineral-based piston engine aviation oil without dispersant additives. Type M contains the same high-quality base oils and viscosity index improvers found in renowned X/C aviation oils.
Type M offers improved cold-temperature starts and quick lubrication, while also offering a full-bodied oil for high-temperature and high-load operations versus use of a single-grade oil. Type M is recommended as a break-in oil for newly overhauled aircraft engines.
