Parent Petroleum Co. X/C® Aviation Oil 25W60 1045490

larger image Phillips 66 X/C® Aviation Oil is an ashless dispersant, multigrade engine oil specifically formulated for year-round use in aircraft piston engines. It provides distinct performance benefits compared to 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. It maintains its film strength under high loads and at high temperatures to protect against wear and piston scuffing. The ashless dispersant formulation helps minimize the formation of engine sludge, varnish, piston deposits and combustion chamber deposits. This results in a much cleaner engine compared to the use of straight mineral oils. X/C® Aviation Oil was the first FAA-approved mineral oil-based, ashless dispersant, multiviscosity aviation engine oil. It has provided outstanding, proven performance in a wide variety of aviation uses since its introduction in 1979, including flight schools, charter and cargo airlines, acrobatic aircraft, spray planes, race planes and virtually any other general aviation application. It is available throughout the United States and is exported to other countries around the world.
