    Rated 5 out of 5 by It Works! 100k smokey, losing oil mini one - symptoms stopped after first use... 05 June 2016
    Rated 5 out of 5 by Stopped smoke! I had white and blue smoke all the time,after using this and driving about 50 miles its all gone!! Just a touch of black diesel smoke on full throttle. 21 May 2016
    Rated 5 out of 5 by Useful if used in context Having read in many reviews about this product, I thought I would try it to confirm my suspicions about my stem seals failing. Contrary to what many people think, there is no miracle cure for a failed engine component in a bottle, at best you contain the concern but a failed gasket is still a failed gasket and a failed seal is still a failed seal, I tried a bottle of this and within 40 miles, noticed a marked and visible reduction of smoke from the exhaust on load and hills and after about 100 miles, no smoke out of the pipe, even on a cold start up, so yes, highly recommended and now I know the seals need doing, for six quid, certainly cheaper and faster than the plethora of checks that would have do be done otherwise to prove this out, word of advice, heat this up before putting it into the engine, it is thick, i mean seriously thick, about half an hour in just off boiling water did the trick but still took ten minutes to decant fully so make sure you have a cuppa ready.... 31 March 2016
    Rated 1 out of 5 by Na Never work. Wast money I never spend any money on this stop smoke ever again 26 March 2016
    Rated 5 out of 5 by Just works... Bought this to try and cure cold start up blue smoke billowing from my 15 year old diesel focus. Didn't think it would do much to be honest. Took a while to pour the whole lot into a warm engine... Started it up next morning and hey presto - no smoke. Unbelievable. And great value for money too. 30 November 2015
    Rated 5 out of 5 by Amazing My 35 year old VW aircooled engine was starting to smoke badly due to worn valve guides. This Stop Smoke product seems to have eliminated the problem - no smoke!!! and hopefully better oil consumption. Amazing! 24 July 2015
    Rated 5 out of 5 by Excellent Product/BMW 1.8 ti compact So I was running dry on on engine oil and forgot to keep an eye on the engine level even when I had a leak, so as I was driving fast I saw lots of white smoke at the back of my car it was fine at lower revs, thought nothing of it, until my colleague told to check the levels I was below minimum, so topped up straight away still smoke but then I used this product and a result no more white smoke, my mechanic was telling me to sell everyone was telling me to sell, it didn't work straight away but after a few hours of driving no more smoke. I don't how long it would last but if it starts smoking again I'm sure to be using this product again. 14 June 2015
    Rated 5 out of 5 by Does exactly what is says I was sceptical of this product as similar solutions seem do do nothing or in some cases cause more problems. This however does exactly what it says on the bottle. Decreases oil burn and increases lost engine compression. I used it for my BMW Valvetronic engine which not only was burning oil at a high rate but also lacked compression. Added this solution and after an hour i took my car out and noticed the difference in compression after only a few miles. And since then also have noticed a considerable decrease in oil burn. i would recommend this to anyone. sure its alot for a small bottle but its less expensive than filling your car with oil all the time. 02 September 2014
