By combining non-metallic, ashless additives with selected high-viscosity index mineral base stocks, it provides exceptional thermal stability, dispersancy, and anti-foaming performance. This specialized formulation leaves no metallic ash residues, effectively preventing harmful deposits in combustion chambers and on spark plugs to reduce the risk of pre-ignition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMFG Part Numbers:\u003c\/strong\u003e\u003cbr\u003e• \u003cstrong\u003eQuart (Case of 6):\u003c\/strong\u003e 550050833\u003cbr\u003e• \u003cstrong\u003e5 Liter (Case of 4):\u003c\/strong\u003e 550045828\u003cbr\u003e• \u003cstrong\u003e55-Gallon Drum:\u003c\/strong\u003e 550041182\u003c\/p\u003e\n\u003ch3\u003eKey Features \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePromotes Engine Cleanliness:\u003c\/strong\u003e Advanced ashless dispersants keep highly stressed engine parts free of sludge, varnish, and carbon build-up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWear \u0026amp; Scuffing Protection:\u003c\/strong\u003e Provides a heavy, robust oil film barrier that protects internal components under high loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized for TBO:\u003c\/strong\u003e Helps aviation powerplants safely reach their full Time Between Overhaul (TBO) by reducing oil consumption and component friction.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMain Applications\u003c\/h3\u003e\n\u003cp\u003eAeroShell W120 is intended for use in four-stroke certified reciprocating piston engines, including fuel-injected and turbocharged variants.
