TYPE M AVIATION OIL

NON-DISPERSANT, MULTI-GRADE ENGINE OIL FOR AIRCRAFT PISTON ENGINES

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

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
