Phillips 66 Type A Aviation Oil 100AD is an ash-less dispersant, single-grade engine oil specially formulated for use in aircraft piston engines. The ash-less 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 (non-dispersant) mineral oils. This oil provides many years of outstanding field performance in a wide variety of aviation applications. It is also FAA approved.
