One 300 ml bottle treats up to 70 liters of petrol and is intended as a preventative maintenance treatment: it disperses soot and carbon residues that can block the catalyst and foul injectors, supports cleaner combustion, and helps reduce excess fuel consumption associated with dirty components. The product is compatible with turbocharged engines and is simple to use — just add to the fuel tank and the cleaning effect works as fuel mixes during driving.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cleaner protect the catalytic converter?\u003c\/h3\u003e\n\u003cp\u003eThe formula targets soot and carbon particles that accumulate on the catalyst surface and in upstream components. By helping to dissolve and disperse these deposits, it reduces the risk of the converter becoming clogged and losing efficiency. This product is designed to work continuously with fuel flow for best results.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRemoves soot and carbon residues that can obstruct the catalyst.\u003c\/li\u003e\n  \u003cli\u003eHelps maintain exhaust flow and conversion efficiency.\u003c\/li\u003e\n  \u003cli\u003eSuitable for use with catalytic converters and turbochargers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the cleaner improve fuel combustion and economy?\u003c\/h3\u003e\n\u003cp\u003eYes — by cleaning injectors and the combustion chamber, the additive encourages a more complete burn of the fuel-air mixture. More efficient combustion typically reduces unburned hydrocarbons and can lower fuel consumption when combined with proper driving and maintenance. The manufacturer states the effect can last up to about 2,000 km after treatment.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClears injectors and combustion deposits for steadier spray patterns.\u003c\/li\u003e\n  \u003cli\u003ePromotes improved ignition and reduced misfires from carbon build-up.\u003c\/li\u003e\n  \u003cli\u003eReported effect duration: approximately 2,000 km under normal use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use the 300 ml bottle in my petrol vehicle?\u003c\/h3\u003e\n\u003cp\u003eUsing the bottle is straightforward: pour the 300 ml treatment into the fuel tank before filling up, or add to an existing tank — the product mixes automatically with the fuel during normal driving. One bottle treats up to 70 liters of petrol, so match dosage to your tank size and servicing interval.
