## Description

LIQUIMOLY Catalytic System Clean Protects the catalytic converter from soot clogging (Sulfurized) Cleaning of injectors and combustion chambers The combustion improver can reduce pollutants to a measurable extent immediately No problem with turbochargers or catalytic converters For preventive use, it can be used in all gasoline engines For up to 70 liters of fuel, use one bottle (300 ml) of this product It is recommended to use it every 2,000 km

Review: P0420のため急遽、ダメ元で2本購入してみました。1本目を投入し、3000〜4000回転をキープしながら、距離が約50キロの高速道路走行を6回ほど繰り返しました。 そのせいもあってか、今のところは点灯していません。 次の給油以降もしばらくは回転数高めで走り、触媒の活性化を促してみたいと思います。 残りの1本は2000〜3000キロほど走ったら、再投入してみたいと思います。
Review: エンジン異常ランプが付いたので、触媒かなと思い試しに購入して使用しました。無事にランプが消え、安く修理出来てラッキーだと思ってます！ 到着は少し時間かかりましたが、使用結果良かったので星5です！

排気系のエラーが約300kmごとに繰り返してましたが、これを使用してからエラーがでなくなりました。ディーラーから高額な触媒交換の見積もりを出されていましたが、しばらくは、触媒交換しなくて済みそうです。
