The liquid looks good 👍 9990 Oil additive
Delivery was faster but I have to come back to review it again after using it. But it looks good.

Perfect
It does work perfectly as an additive. Cold start is smoother and a bit of reduced engine noise. Remember this is not a magic potion and will not solve any engine problems. Need to put in a few hundred jms and check oil consumption and colour

Posseggo una vecchi Fiat topolino 1950 con motore ormai da rifare. Spesso l’auto funzionava a tre cilindri causa candela sporca di olio. Dopo l’uso di questo prodotto ora l’auto è più di un mese che non da problemi. Ovviamente parliamo di soluzione temporanea di cui beneficiare finché dura. Nulla di definitivo

Hätte es nicht gedacht, aber das Additiv hat bei meinem Honda Jazz (1,4 idsi) von 2006 mit 164.000km das Motorgeräusch (klakkern, kalt unter Last) fast komplett beseitigt! Bin echt positiv überrascht von dem Produkt

Ich habe bisher immer ein "deutsches" Produkt verwendet. In halbwegs günstigen 1ltr. Dosen. Doch jetzt gibt es das Produkt, in der 1ltr. Menge kaum noch zu haben und wenn, dann zu einem gesalzenen Preis. Somit bin ich auf Mannol gekommen. Die Wirkung ist die gleiche, wie mit dem teuren Produkt. Unser "Fuhrpark" besteht nur aus Fahrzeugen mit mehr als 200.000km Laufleistungen. Alle Motoren laufen rund, geschmeidig und in Punkto Öl- / Kraftstoffverbrauch liegen wir im "Neuwagenbereich". Meine Empfehlung für alle Motoren ab ca. 100.000km Laufleistung!!!
