Phillips 66 Type M 20W50 Break-In Piston Engine Oil - 1 Quart

The 1045575-QT is 1 quart of Type M 20W50 piston engine oil usually used for break-ins after overhaul.

What is Phillips 66 Type M 20W50 Engine Oil?

Phillips 66® Type M Aviation Oil is an ashless, non-dispersant, multi-grade engine oil recommended for use in aircraft piston engines where the operator prefers a mineral oil-based engine oil that does not contain dispersant additives. It provides easier starting and quicker oil circulation at low temperatures compared with single-grade mineral oils while maintaining high film strength at high temperatures and under high loads for protection against wear and piston scuffing.

Type M Aviation Oil typically is used as break-in oil for newly overhauled engines where all-mineral type oils are recommended. The multi-grade formulation helps reduce cylinder glazing tendency during break-in. Break-in normally is accomplished in less than 25 hours of engine operation.

Applications of Phillips 66 Type M 20W50

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