Overview

Phillips 66 Type A Aviation Oil is an ashless dispersant, single-grade engine oil specially formulated for use in aircraft piston engines. The ashless dispersant formulation helps minimize the formation of engine sludge, varnish, piston deposits and combustion chamber deposits, resulting in a much cleaner engine compared with the use of straight (nondispersant) mineral oils.

Type A Aviation Oil has many years of outstanding field performance in a wide variety of aviation applications. It is available in two grades, 100AD (SAE 50) and 120AD (SAE 60). Both grades are FAA approved.

Features

  • Ashless dispersant helps minimize engine sludge and varnish deposits for a cleaner engine
  • High film strength for protection against wear and piston scuffing
  • Protects against rust and corrosion

Phillips 66 oil so far seems to be working well in my Pacers O-290D2 Lycoming. It is a couple bucks cheaper a quart then Aeroshell as well.
