A spa weekend for your injectors.
Genuinely cannot believe how effective this product really is. I thought my Supercharged V8 was in tip top shape until I poured a bottle of this in the tank. It no longer has an intermittent misfire at high RPM, it is even smoother than it was before. The engine sounds showroom fresh. The car is much more economical, pulls harder under harsh acceleration and is considerably smoother on both idle and pull away. Overall I would say not only does this product live up to every claim it offers exceptional value for money, as you only need one can every 2000 miles and the results are delivered very quickly.

Brought for my borther
I read the reviews and bought for my brother who was struggling to get his car working. This worked an absolute treat it was recommended to me by another family member, don't let the low price put you off this is Brilliant and great value for money, it's easy to use and works really well cleaning the injectors, no leaking from the can so no product wasted. If you're needing something like this don't wait just buy! It does exactly what it says it will.

GgEine gute Möglichkeit, das Auto zu reparieren, ohne es zu zerlegen und ohne Geld auszugeben. Vor diesem Mittel lief der Motor rau, unruhig bei niedrigen Drehzahlen, ich musste dieses Mittel in den Tank gießen und 50+ km fahren, da der Motor begann, glatter, leiser und weicher zu laufen. Ich bin zufrieden, ich empfehle es!

私の車は直噴エンジンを搭載しており、特に燃料品質が悪い場合、カーボン堆積が深刻化することで悪名高い。 様々なガソリンスタンドで給油せざるを得ず、時間の経過とともにエンジン状態が悪化していくのを実感した。そこでこの製品を購入し、まずほぼ空のタンクに添加した後、高品質燃料を提供していると確信しているスタンドの新鮮な燃料で満タンにした。 最高の効果を得るには「イタリアン・チューンアップ」と呼ばれる方法が必要です。つまり、数分間ずつエンジンを激しく回転させ、数回加速を繰り返すことです。これにより添加剤が十分にインジェクターに到達し、スラッジを燃焼させるのに十分な熱が発生します。高速道路を1時間走行後、エンジンの調子が改善されたのを実感しました。今後は3ヶ月ごとに使用します。

Liqui moly qui a déjà fait c'est preuve. Produit utilisé sur un 3008 qui avait des claquement injecteur et ça lui a pas fait de mal .bien le mettre réservoir presque vide et mettre la moitié d'un plein et prévoir d'aller sur voie rapide pour une session de 3 a 4000 milles tours pendant au moins 30 minutes...

Qualità ottima ed indispensabile per una pulizia regolare prima di ogni tagliando. Va applicato circa ogni 2000/3000 km come parte della manutenzione periodica del motore per mantenere il sistema di iniezione pulito.
