Wynn'sStop Smoke For Oil Additive For Reducing Petrol & Diesel Engine Exhaust Emissions

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

Does what it says on the tin opens easily pours with no spillage. Has greatly reduced the smoke from the car. Will buy again when close to 4k miles

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.

Second time using this product in my slowly leaking engine. After a service it seems to be worse but I add a tinnof this and it helps a lot. Also stops the smoking. Saves money on oil and touch wood stops the engine light coming on.

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

I thought these additives were a load of tosh... I tried this on the off chance after a bodger at work suggested giving it a go.I have a 2007 Mini with exceptionally low mileage but because of infrequent use, the valve stem seals leak a bit resulting in smoke and oil use. I get that this stuff doesn't really fix the problem it just masks the symptoms but it is actually working and my oil use has gone down significantly 😁It'll keep me going until I can be bothered to change the seals anyway. Well worth a go for the cost.

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

This wynns stop smoke immediately stopped my car from smoking and appears to work very well.Not sure on longevity but a few weeks after adding to engine there's still no smoke.
