Phillips 66 X/C Aviation Oil 20w-50 Engine Oil is an ashless dispersant, multigrade engine oil specially formulated for year-round use in aircraft piston engines. Phillips 66 X/C Aviation Oil 20w-50 Engine Oil provides distinct performance benefits compared with single-grade engine oils, including easier starting and faster oil circulation at low temperatures, reduced warm-up time, and reduced oil consumption in most engines. Phillips 66 X/C Aviation Oil 20w-50 Engine Oil maintains its film strength under high loads and at high temperatures to protect against wear and piston scuffing. Phillips 66 X/C Aviation Oil 20w-50 Engine Oil's 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. Phillips 66 X/C Aviation Oil 20w-50 Engine Oil was the first FAA-approved mineral oil-based, ashless dispersant, multiviscosity aviation engine oil. Phillips 66 X/C Aviation Oil 20w-50 Engine Oil has more than 20 years of outstanding, proven performance in a wide variety of aviation uses, including flight schools, charter and cargo airlines, acrobatic aircraft, spray planes, race planes, and virtually any other general aviation application.
