Liqui Moly 2030 Pro-Line Fuel System Cleaner, 500 ml

Mejoró el consumo de combustible (tampoco es algo radical, pero definitivamente ayudó), la reacción al acelerar mejoró notablemente aparte de que de repente el coche al estar parado sufría de variaciones en las revoluciones y esto se corrigió. Bastante satisfecho con los resultados, siempre había tenido mis reservas al respecto de este tipo de productos; este en específico 👏

J’ai utilisé le Liqui Moly Pro-Line 2030 Nettoyant lors de l’entretien de mon moteur et je suis vraiment impressionné par son efficacité. C’est un produit de qualité professionnelle, parfait pour dissoudre la saleté, l’huile et les résidus tenaces sur les pièces mécaniques. La formule est puissante et agit rapidement : dès l’application, on voit la graisse et les dépôts se décoller facilement. Je l’ai utilisé sur mon bloc moteur, mes pièces en aluminium et mes supports moteurs, et le résultat est impeccable. Tout redevient propre, sans laisser de film gras ni de traces. Le gros avantage, c’est qu’il n’attaque pas les joints ni les plastiques lorsqu’on l’utilise correctement, ce qui est rassurant surtout sur un moteur complexe comme celui de mon Audi. La pulvérisation est précise et permet de bien cibler les zones sales. Franchement, c’est un excellent produit à avoir sous la main si vous aimez entretenir votre véhicule comme un pro. Liqui Moly reste une référence, et ce nettoyant ne fait pas exception.

Seriously, this product works. I have a G63 that was not performing how it should in terms of responsiveness to accelaleration but once I used this I noticed a crazy surge in accelaleration compared to before using the product. I trust this company as I have used two other products from them and they all work. Couldnt be happier with the purchase.

I’ve now used LIQUI MOLY Gasoline System Cleaner on all three of my cars with over 80,000 -170,000 miles—and the results speak for themselves. I have a 2004 Mercedes ML350, a 2012 Hyundai Elantra Limited, and a 2016 Lexus RX350. This product has helped each one run more smoothly and efficiently, even at their age and mileage. Mercedes-Benz ML350 (W163): With a high-mileage V6, this SUV had started feeling a bit sluggish—especially on cold starts and uphill acceleration. After using this cleaner, the throttle response improved noticeably, and the idle became more stable. It didn’t suddenly turn into a new engine, but it definitely felt less bogged down and more responsive, especially at low RPMs. Hyundai Elantra Limited (2012): This car showed the most fuel economy improvement. Before use, I averaged 25–27 MPG. After running a full tank with LIQUI MOLY, it bumped up to around 30 MPG, and the engine felt smoother under load. It’s a small gain, but for a daily driver with over 86k miles, that kind of improvement adds up over time. Lexus RX350 (2016): This engine was already running well, but I use the cleaner bi-annually as preventive maintenance. I noticed slightly better responsiveness when accelerating, especially from a stop. It’s subtle but definitely there. I believe using this regularly helps prevent future build-up and keeps things running optimally. Important Note: These products aren’t magic potions that make your car run like new—but they do help clean and restore your fuel system over time. I use it as part of my bi-annual maintenance schedule. Combined with using high-quality gasoline and regular servicing, this cleaner helps keep all three of my high-mileage cars running smoothly and reliably. Bottom Line: LIQUI MOLY is a well-engineered, trusted brand, and this cleaner has proven itself across three different engines. I highly recommend it—especially if your car has 100,000+ miles. It’s affordable, easy to use (just pour it in before filling up), and makes a real difference when used consistently.
