Excellent product that really works
My Citroen Picasso C3 has about 100,000 miles on it and the engine was starting to sound a bit noisy so a friend recommended I try Wynns oil treatment. I noticed the difference almost immediately when I took it for a test drive. The engine was much quieter and felt more nippy as I increased speed. It's been about 3 weeks now since I added it to my engine oil and my car feels much newer now and a pleasure to drive it. I can't believe the difference it has made to my engine and I highly recommend it to anyone. Excellent Product.Read full review

Wynn's Oil Treatment
I have used 'Wynn's products' in every vehicle I have owned since the early Seventies. There has been a few.
They have never let me down. I will continue to use Wynns whilst I am still capable.

Performance improver.
I have used this several times to improve my engine performance. Recently I noticed that my tappets were a bit noisy when I opened the oil cap when the engine was running. After about 20 miles of driving the tappet noise has vanished.Read full review
