AeroShell Oil W 100 is a non-ash dispersant oil for use in aircraft piston engines. It combines non- metallic additives with selected high viscosity index base stocks to give exceptional stability, dispersancy and anti-foaming performance. These additives leave no metallic ash residues that can lead to deposit formation in combustion chambers and on spark plugs, which can cause pre-ignition and possible engine failure. Bottle Size: 1 Quart / 946ml Promote engine cleanliness and helps keep engines slidge free Helps reduce oil consumption Helps engines reach TBO (Time Between Overhaul) Protects highly stressed engine parts against scuffing and wear Main Applications: AeroShell W Oils are intended for use in four-stroke cycle (four-cycle) certified reciprocating piston engines, including fuel-injected and turbocharged engines Most radial engine operators use AeroShell Oil W120 in warm weather operations with AeroShell Oil W100 or AeroShell Oil W 15W-50 being used in cooler ambient temperatures. AeroShell Oil W100 or AeroShell Oil W 15W-50 are the common choices for most operators of Lycoming and Continental flat engines. AeroShell W Oils are not recommended for use in automotive engines. For automotive engines converted for use in aircraft, the specific engine manufacturer or the conversion agency should be consulted for proper oil recommendation.
