    UN BUEN PRODUCTO.
  
  

*by C***U on Reviewed in Spain on 7 May 2023*

Para mi diésel de 10 años va perfecto. 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.

    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!
