I have used this in my taxi (Seat Leon 1.6 TDI) since I ourchased it 2nd hand and 3 yrs old. I always change the oil when the dashboard light advises and have always added ceratec. At over 100,000 miles, the car is running as smooth as it did at 60,000. I'll continue to use the Ceratec every oil change to get the best longevity from the engine.

Who can tell if these additives work? Going off the knowledgeable people on car forums, too many said it is good. Gave it a 3 star only because on the oil change after the additive my mechanic said the oil was weak and a creamy colour - thats the same colour of the Ceratec....who knows. Wont use again just in case.

...I read about it in the Porsche Cayenne forum that it has very good reviews but I was a bit sceptical. I bought it and mixed is as described into the oil. I would recommend a suitable container. I have not used it in my Cayenne but I will as soon as the next service is due. I used in instead in my race car. I have to say that I had some problems with idling. It wouldn’t idle for too long before the engine Stopps. Now after a couple of minutes the engine sounded quieter and was idling for much longer. I’ll have a booked a dyno next week but the difference was noticeable within minutes.

Very good product works instantly and protects engine life and components. Highly recommend for high performance vehicles. Self mixing and increases oil service life.

This is a must for all those people who can not afford to relace engine parts. I added this too my oil and pretty soon annoying noises disappeared
