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.
