Wynn's Stop Smoke - Reduces Exhaust Smoke Due to Oil Burning - Improves Compression, Viscosity & Engine Performance - Compatible with All Oils & Engine Types - 325ml

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.

I tried all sorts of stop smoke oil an engine none of them worked until I tried this. My old Mercedes was blowing blue smoke on idle probably piston rings or valves need doing which is highly expensive. This however completely remove the smoke after one application of the oil, absolutely amazing

Working well not sure how long it’ll last for but good value for money and the engine is still running smoothly

Been burning a crazy amount of oil in my engine. Mechanic told me it's my piston rings. More economical for me to get a new car than the repair cost. Using this has cut down my oil consumption by about 80% so I can still use my car while I look for a new one

Smoke didn't seems any worse or better, so hard to tell if worked...

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

Looks like is doing the job. Have use it on a Peugeot 207 1.4 diesel engine. Have changed the oil and add the product. Less than 30 miles drive and I already see improvement on exhaust smoke, like massive improvement. Engine sounds much better and compression improved.I would definitely recommend and will use it again.

Really simple to use, didn't stop all of the smoke but did reduce it and improve fuel efficiency, reduced rattle in the engine and did what we needed
