It combines detergents, cetane enhancement, lubricity agents, corrosion inhibitors and demulsifiers to address common fuel problems — from injector deposits to moisture and cold‑weather performance — without affecting exhaust aftertreatment systems.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this additive improve engine performance?\u003c\/h3\u003e\n\u003cp\u003ePerformance Formula works on fuel delivery and combustion. Detergents remove deposits that impair spray patterns and injection timing while the cetane improver promotes faster ignition and a steadier burn, which can yield smoother operation and restored power.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRemoves injector and pump deposits for consistent spray patterns\u003c\/li\u003e\n  \u003cli\u003eRaises effective cetane for improved ignition quality\u003c\/li\u003e\n  \u003cli\u003eHelps recover lost horsepower and throttle response\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it help my fuel economy and emissions?\u003c\/h3\u003e\n\u003cp\u003eBy improving combustion efficiency and cleaning the fuel system, the additive can reduce unburned fuel and soot formation.
