The core reason to consider this product is protection: it is formulated to shield the catalytic system from oil poisons and to reduce phosphorus and zinc retention at the catalyst inlet, which can help maintain converter efficiency and avoid early replacement. It is sold as a 16 oz. bottle in a 6-pack and is intended for periodic use with regular fueling.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConverter protection:\u003c\/strong\u003e Designed to protect and treat the catalytic converter and exhaust system from oil poisons that degrade catalyst performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel economy assistance:\u003c\/strong\u003e Customers report improved mileage after use, indicating it can help increase fuel efficiency when used as directed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmission safeguarding:\u003c\/strong\u003e Reduces phosphorus and zinc retention levels at the catalyst inlet to help maintain catalytic efficiency over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple dosing:\u003c\/strong\u003e One 16 oz. bottle treats up to 60 liters (16 gallons) of fuel or can be dosed at 30 mL per 3.8 L (1 ounce per gallon) for convenience.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-replacement step:\u003c\/strong\u003e Recommended for use before replacing a catalytic converter to rule out contamination issues first.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal fit:\u003c\/strong\u003e Works on all engines and is safe to add anytime to the fuel system as a preventative or corrective measure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe product suits drivers and independent mechanics who suspect oil fouling or contamination of the catalytic converter or who want a preventive treatment to maintain exhaust system health.
