Phillips 66 Type M Aviation Oils are designed for use in aviation engines where the operator prefers continued use of all-mineral type oil. It does not contain dispersant type additives. This oil can be used as break-in oil for newly overhauled engines when an oil of this type is recommended. Break-in is normally accomplished in less than 25 hours of engine operation.

When compared to single-grade oils, Type M Aviation Oil 20W-50 offers improved cold temperature starting, quicker flow of oil to the cold engine, plus a full-bodied oil for high-temperature, high-load operation

Features & Benefits

• Easier starting and quicker oil circulation at low temperatures compared with single-grade oils
• High film strength for protection against wear and piston scuffing, even under high-load conditions, such as takeoff, and at elevated operating temperatures
• Reduces cylinder glazing tendency during break-in, compared with single grade oils.

Applications:

• Aircraft piston engines where the operator prefers a non-dispersant engine oil
• “Break-in” oil for newly overhauled aircraft engines

Meets Requirements of:

• SAE Standard J1966
• U.S. Military Specification MIL-L-6082 (obsolete)
• QPL approval number: N06L1-20W-50 (Type M)
