Pero Amazon debería ver como dejarlo en un precio mas contenido, nos esta obligando a buscarlo por otro sitio. Es alemán que contacte con Amazon Alemania y busquen una solución. ### ⭐⭐⭐ Flacon percé et vide *by D***A on Reviewed in France on 19 June 2020* Bonjours sur les 3 flacon que j ai reçu il y en avait 1 qui était percé et vide ### ⭐⭐⭐⭐⭐ Pflege für den Diselmotor *by H***S on Reviewed in Germany on 29 November 2016* Sinn und Zweck eines solchen Additivs ist es den Motor bzw den Verbrennungstrakt zu reinigen und zu pflegen und das macht dieses Produkt.Ich kaufe gerne Produkte von Liqui Moly, da es ein deutsches Unternehmen ist und die Produkte ordentlich geprüft und getestet werden.Habe das Produkt in meinem BMW f11 520d im Einsatz.Dieser hatte temporär im Leerlauf ein unruhiges verhalten.Da ich das Auto gebraucht gekauft habe mit ca. 60000km auf dem Tacho und nicht wusste mit welchem Diesel er bedankt worden ist bzw ob er auch mal auf der Autobahn ordentlich frei geblasen wurde, fand ich die Anwendung sehr nützlich.Nach der Anwendung merke ich Unterschiede.Standgas läuft ruhig, leicht besserer Durchzug und etwas weniger Verbrauch 0,1-0,3 l weniger auf 100km, bei vergleichbarer Fahrdynamik.Ab jetzt gönne ich den Bulliden Liqui Moly 2T Motoröl (1052) zum Diesel. Gleiche Wirkung aber günstiger bei gelegentlicher Anwendung von ca. 150-200ml Zugabe bei voller Tankfüllung (70l).Ich bin sehr zufrieden! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/129693582-liqui-moly-5139-system-diesel](https://www.desertcart.pl/products/129693582-liqui-moly-5139-system-diesel) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-28*
