When added to petrol, it loosens and dissolves carbon deposits and soot that can impair injector spray patterns and block catalyst passages. The manufacturer specifies that one bottle treats up to 70 liters of fuel and the effects can persist for around 2,000 km, making it a convenient service between professional cleanings.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this product protect the catalytic converter?\u003c\/h3\u003e\n\u003cp\u003eThe blend contains detergents and dispersants that reduce soot buildup, which helps keep the catalyst passages clearer and maintain exhaust flow. By minimizing clogging, it reduces the risk of premature catalyst degradation and helps stabilize backpressure in the exhaust system.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBreaks down soot deposits on the catalyst surface\u003c\/li\u003e\n  \u003cli\u003eHelps keep exhaust passages from becoming constricted\u003c\/li\u003e\n  \u003cli\u003eCompatible with turbochargers and catalytic converter systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it actually clean the fuel injection and combustion chamber?\u003c\/h3\u003e\n\u003cp\u003eYes — the formulation targets injectors and combustion chamber deposits to improve spray pattern and combustion efficiency. Cleaner injectors and chambers support more complete fuel burn, which can lead to smoother idling and more consistent performance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDissolves varnish and carbon on injector nozzles\u003c\/li\u003e\n  \u003cli\u003eRemoves combustion chamber carbon layers that impair compression and ignition\u003c\/li\u003e\n  \u003cli\u003eMixes automatically with petrol when added to the tank\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use it and how long does the effect last?\u003c\/h3\u003e\n\u003cp\u003ePour the 300 ml bottle into up to 70 liters of petrol before filling or during refueling; it mixes automatically with the fuel.
