Works great
I have a 2019 Vauxhall Grandland X with a noisy engine. I was recommended this as a cheap way to try and fix the issue. I followed the instructions adding this to a warm engine that had time to settle. To my amazement it stopped the noisy knocking engine within about 30 seconds. I have now been running this for a few thousand miles and the engine is smoother and quieter. Definitely worth the money.

Amazing stuff seems to have worked!
Didn't really believe the reviews as this is the first time using a product like this but I can honestly say my engine seems to run smoother and not as loud. What I did is place the oil treatment bottle in a container of hot water (again in the bottle not diluted with water..) to make it more runny and take my car on a 20 minute drive to get the oil flowing and warmed. Came back put the full bottle in (Audi a5 3.0 tdi ~7-7.5L engine oil) so could have got away with 1 1/2 bottles of this but didn't want my oil to be too thick due to it being winter! Then went on another 30 minute drive and within 10-15 minutes I could tell my engine felt as it was running smoother and not as loud. Engine seemed more responsive but that could also be due to running a cycle of STP injection cleaner in my tank. Just a tip wear gloves as it's a pain to get off your skin 🤔

Verwende es im OM615. W115 Bj72 (220D). Es macht das Öl bei Betriebstemperatur stabiler. Ohne diesen Zusatz habe ich nach einer Autobahnfahrt 1,5bar Öldruck im Stand. Mit Zusatz, selbe Strecke, gleiche Geschwindigkeit = 2,0bar. Bin sehr zufrieden, es muss sich aber Einlaufen und ich werde es wieder verwenden. Gibt auf YT einen guten Vergleich; STP oil Treatment Safe for your engine?

Kaliteli bir ürün.Motora dökmesi biraz uzun sürüyor.Çünkü akışkanlığı çok az.

Prodotto buono arrivato subito e devo dire che gli effetti si sono subito, infatti meno rumori del motori e anche più fluida la guida...

le prestazioni sono molto chiare, sembra che il motore sia piu' silenzioso e molto piu' fluido. controllero' al prossimo cambio d'olio..
