Phillips 66 Type A Aviation Oil 100AD 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. This oil provides many years of outstanding field performance in a wide variety of aviation applications. It is also FAA approved.
