Wynns Stop smoke additive
This is first time that I have used this product and I am genuinely amazed with it. It does exactly what it claims it does reduces smoke and noise while increasing the performance slightly. However I haven't noticed any significant change in mpg but that's no real disappointment as my vehicle is pretty good anyway. My 2ltr HDi has over 202,000 registered miles. I will now use this every time that I change the oil and filter. Money well spent !Read full review

Reduced smoke
My old diesel was smoking quite bad,, added to warm engine and now there is a very big reduction in smoke and smell. So I’d say did it’s job. Car is still a bit smoky at high revs but it’s an old diesel.Read full review

As it Says On the Tin
This has had some effect on the amount of smoke from my engine but, given that my mileage is more than 265K, it has a lot to do!
I intend to run it for a few months and repeat the treatment.

Wynnes Oil Additive.
Good additive and does improve economy. This oil will assist but not totaly get rid of smoke if your engine is worn.
