Phillips 66® 120AD Aviation Oil (SAE 60) is an ashless dispersant, single-grade engine oil specially formulated for use in aircraft radial 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 (non-dispersant) mineral oils.
