Saved us a garage repair bill after engine light cleared.

I used this to clean the CAT on my daughter’s car having reset an engine warning light for her. The light has stayed off, the car runs smoother, quieter and a large repair bill has been avoided. Easy to use, we waited until she had only 15 litres of fuel left in the tank, as per the instructions and it’s been highly effective.

Works well. Very happy with the result

My engine management light had been off and on (mainly on) for many months with a cat efficiency error. I'd sceptically tried three bottles of Cataclean spread over this time with no effect. On the verge of having a mechanic friend get involved I thought I'd have one last go with Wynn's. Within minutes of adding the light had gone off and after around 100 miles the engine certainly feels smoother and more responsive, reporting better mileage on the computer. Still early days but it seems to have done the trick and saved me a bunch of cash. Wish I'd tried this one first!

Instructions in GERMAN!!

Just received this product. Much to my amazement the instructions are in GERMAN! Yes, I did peel the label.Surprisingly enough, I do not speak German.Come on Amazon please advise me of the logic behind that stroke of brilliance, this is the UK!!Yes I can and did look up the instruction online but there may be people who cannot and anyway why should I?Not a good start.

Cleared fault quickly

Engine light came on and diagnostics showed o2 sensor fault. Thought I would just give this a try on a nothing to lose basis.One week later, no engine light and no fault showing. Very pleased.

Excellent stuff especially for the catalytic converter and long lasting.

Quick delivery and excellent condition and really good stuff especially for the ford focus ecoboost cars. Value for money as it lasts for 3 months. I'd highly recommend this product to family and friends and other people but their is an even better one now which has dual action.

Sensor 2 problems on car

Bought this item as I was needing my oxygen sensor replaced. Added it to my fuel tank and in the space of 20-30 miles my engine light went off.I would highly recommend this product even just as a precautionery measure. It has saved me nearly £180 in garage fees.Well worth the money
