Phillips 66 M Type
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 fi lm 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.
