Petrol Engine Leaks Fixed
Added 1 liter of the liquid Moly to my land rover series 3 petrol engine which had oil leaking almost every seal, gasket. That was last December. I've since driven approx 200 miles and surprisingly the cardboard under the engine is now dry. Was sceptical to the claims, paid more for this product and am happy with the results so far. A leak free land rover, unheard off but true.

Good price for the quality
Nice and thin, blends well with oil. Is starting to rejuvenate crispy rubber seals and gaskets. Oil loss is down to a spot or two after 300 miles. Won't stop oil overnight.... so give it time to work

I think it worked
Out it in the car and my oil leak greatly reduced. Rarely need to top up oil

Stopped leak
I put the whole litre in my 2008 Vauxhall Vivaro 2.0cdti. I had a small leak from the turbo, it stopped and no smoke. This is only a stop gap until I get a new turbo fitted in January 2025.

Terrible Waste of Packaging
Excellent item as always with Liqui Molly. However, a terrible waste of packaging, the box was four times bigger than the item and was packed out with paper, terrible waste and not at all unusual for Amazon.

Repito producto en envase diferente. Suerte que el recipiente es metálico, de no serlo, hubiese llegado un contenedor sin contenido. El bote recibido está lleno de abolladoras producto de un mal trato evidente. No ha perdido contenido después de todo, creo que servirá.

Au début un peu sceptique car au bout de 700/800km comme indiqué sur la bouteille, il y avait toujours des petites fuites. Mais après 1000km environ, les fuites on commençaient a diminuer pour s'arrêter. Je conseille donc de rouler un peu plus que ce qui est noté sur le flacon. Utilisé sur un vieux Renault master de 1999 moteur sofim, connue pour être une vraie passoire. Après avoir changé les joints spi de vilebrequin, d'arbre à came, joint de cache culbuteur et joint de carter d'huile, les joints de carter de vilebrequin était aussi HS cependant très coûteux à changer. Ce produit à permis d'éviter le démontage...

You will see the results in 2000+ km. don’t expect immediate results

Lo utilizzo da un po' di tempo e ho risolto l'improvviso consumo di olio motore, lo uso per ogni cambio d'olio e in giusta misura anche per il rabbocco.

VW Polo und Peugeot Cabrio. Hat den Ölverlust deutlich verbessert, wirkt definitiv.
