Not the snake oil you would expect it to be
Reviewed in the United Kingdom on 2 May 2018
Never really been a fan of these 'snake oil' oil additives, but after doing quite a considerable amounts of research on this product, I decided to give it a go.
My own personal 2012 2.0TDI Bluemotion Passat 140 ~ 86,000 miles:
Contrary to the advised 'put it in at oil change interval with fresh oil' I decided to put it in half-way-ish through my oil change interval into some used, but good quality oil, I removed 300ml of oil and added this stuff in. My theory was that if I noticed any detrimental effects of the additive, I could do the oil change now and only lose out on the £17.
I added it in and after a few days I hadn't really noticed any difference, in fact for the best part of a week ,there didn't 'seem' to be any change. I do sufficient 'gentle' warm up/cool down driving at either end of my morning and evening motorway commute 5 days a week.
The following Monday though, around 400 - 500 milesafter the addition of CeraTec, I noticed that the first cold start up and cold idle were noticeably quieter/smoother, this engine is quite smooth and quiet anyway (for a diesel) but this was noticeable, and at sub-zero temperatures.
On the gentle drive to the motorway (usual stop-start, traffic-lights driving) it was still noticeably smoother and quieter than before, feeling more eager to 'go' and less restricted, but the shocker here (for me) was the journey up the slip road onto the motorway, by the time I get to this point on my journey my oil is sufficiently warm for me to deem 'standing on it' acceptable, so stand on it I did.
Well, all I can say is wow! There is a difference and it is not subtle, slight or noticeable, it is stark!
The car took off up the slip road overtaking pretty much everything along the way and was happily revving up to around 4Krpm before I changed up, the engine was singing, it loved it, I did too.
I have not been able to recommend this to enough people, usually receiving the same sceptical 'oh yeah' snake oil responses, but I've said to them, and I'll say the same to you, try it and give it a week!
The first oil change after the addition of this stuff is coming up in around a week or two so I'll be interested to see if the effects remain after a week of just having fresh oil in, if not, I'd happily stump up another £17 to re-treat for the next 8000miles.
