Review: 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!
Review: 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
