Works Really Well!
I’m very happy with Wynn’s Stop Smoke. It arrived on time and was easy to use. I noticed a clear difference afterwards, the exhaust smoke reduced significantly, and the engine felt smoother and more responsive. It also seems to improve compression and overall performance. Great product and definitely worth trying if your car is burning a bit of oil!

It actually worked
Gone from a lot of soot in the exhaust and burning oil, to very little. Really pleased with it. Will see how long it lasts but I can live with the odd can of this in comparison to constantly filling up the oil

Worth the cost
Had no effect but points me to the real cause, so worth the money from a diagnostic point of view

Worked for me!
WOW! Got a X5 30d 2011 which has been smoking in the morning. Whenever I start the car and leave it for about 10mins, it start to smoke for about 5mins and then stop. This happens each time the car is started from standing still. Was told the Valve Stem Seals needed replacing. So I thought let's look for a decent temporary solution and thats when I got Wynns Stop Smoke after reading the reviews. So I warmed the car up for 15mins (idelling), turned it off, put the Wynns in, left it for 2mins, started it again and let it run for 10mins and turned it off. After about 20mins I took it for short 5miles drive (normal driving). And it was still smoking, i thought at this point its a waste. Flip it to the next day, I thought id take this to drop the kids off, started the car, drove it 10miles and gues what. . .NO SMOKE. Im not getting ahead of myself and will keep a eye on it and report back 1 week after today. I added 2 pics of before and after.. couldn't load a video but will give you a idea.

Did not work in my car.
My Mini Cooper with 1.6 NA petrol engine is having a bit smoke due valve steam seals on its way out. Tried this but did not work. I guess worth the try for such little money.

Does exactly what it says on the tin
Used this product on my Ford Focus TDCI. My car had been blowing lots of blue smoke from the exhaust, which obviously indicates an issue that could prove costly, but after using this the smoke has more or less disappeared. It means I can drive my car without the embarrassing smoke until I decide to replace my vehicle. Does exactly what it says on the tin
